Magneto hybrid nanofluid flow with activation energy and chemical reaction through an impermeable stretching elastic cylinder

ABSTRACT This article focuses on the study of incompressible, steady, and electrically-conducting hybrid-nanofluid flow through an impermeable stretching elastic cylinder. The base fluid chosen for the study is water and two nanoparticles, namely Cu and graphene, are used for the hybrid nanofluid, while Cu is used for the usual nanofluid. The system takes into account the presence of a chemical reaction, activation energy, and a magnetic field. A comparative analysis is performed to examine the impact of these factors on the hybrid nanofluid and usual nanofluid. The governing equations are transformed into non-dimensional form using similarity transformation and solved using the RK-4 method. The study utilizes graphs and tables to analyse the influence of relevant factors on the flow profile. The results indicate that the temperature decreases with the activation energy factor but increases with the chemical reaction and curvature factors. Both heat and mass transport processes are enhanced by the activation energy parameter, while the opposite effect is observed for the chemical reaction parameter.

Simulation of Proton Exchange Membrane Durability Under Fuel Cell Vehicle Operation – a Fundamental Study

Proton exchange membrane fuel cells (PEMFCs) have been proven to be a promising candidate to replace combustion engines due to their zero-carbon emission and high power densities. Despite the recent success in PEMFC commercialization, a number of challenges such as high cost and difficulty in lifetime estimation still hinder their further development. PEMFC durability tests require a long time to complete; therefore, durability predicting models are increasingly important as a supporting tool for further development and implementation.Fuel cell membranes undergo a variety of dynamic conditions during regular operation such as varying temperature, humidity, current density, and cell potential. The cyclic variations of humidity and temperature (hygrothermal variations) during dynamic operation lead to swelling and contraction of the membrane. The fluctuating stress caused by the continuous expansion and contraction of the membrane when confined within the cell leads to mechanical membrane degradation. The recurring swelling and contraction of the membrane which stem from water content changes in the membrane cause fatigue and creep and ultimately the formation of pinholes, cracks, and tears [1-2].Chemical membrane degradation occurs when radicals such as hydroxyl and hydroperoxyl are formed and attack the membrane and is escalated by high operating cell potentials. Chemical degradation results in decay in the ionomer chemical structure, membrane thinning, increased gas crossover, and potential electrode shorting [3]. The outcomes of such degradation are aggravated in the presence of mechanical degradation [4]. Hence, the study of combined chemo-mechanical membrane degradation is crucial for overall fuel cell membrane durability [5].The objective of the present work is to establish a predictive membrane lifetime simulation tool designed to represent chemo-mechanical membrane degradation under various operating conditions for automotive fuel cell applications. To this end, a statistical model is developed based on the membrane fibrillar morphology presented by El Hannach et al. [6-7]. A network of fibre bundles is generated to represent the membrane structure where any bundle is assumed as the primary building block of the membrane [8-10]. Each bundle contains an aggregate of backbone chains with typical mechanical and chemical properties. Mechanical and chemical degradation rates are separately studied and coupled in the model. The thermally activated breaking rate of each fibre is calculated to evaluate the mechanical degradation rate at any given time. In order to calibrate the mechanical degradation rate in the model, the mechanical degradation of a reinforced membrane under cross-pressure accelerated mechanical stress tests ( p-AMST) [11] is investigated to obtain the membrane fatigue lifetime for a variety of cross pressures and temperatures. Then, the genetic algorithm is successfully applied to optimize the experimental parameters considering the least squares method. Furthermore, accelerated membrane durability tests (AMDT) carried out by Macauley et al. [12] are considered to calibrate the chemical degradation rate parameter in the model. Finally, the fully calibrated model is used to estimate the membrane lifetime under realistic fuel cell vehicle operating conditions (e.g. drive cycles).Fuel cell components experience different degradation mechanisms. In this regard, this modelling framework on the membrane lifetime can be used in conjunction with other methodologies on the cathode catalyst lifetime such as [13-14] to scrutinize the key factors and their impacts on fuel cell durability under similar operating conditions.

Effect of Forchheimer on Hydromagnetic Flow Inspired by Chemical Reaction Over an Accelerating Surface

This study investigates the effects of Forchheimer and Lorentz on paired heat and mass transfer by MHD twinned convective flow of a Newtonian fluid with the chemical reaction effect through porous media over an accelerating surface. The governing equations of the physical model are the non-linear coupled PDEs, which are converted to a system of coupled non-linear ODEs with a suitable similarity transformation. By implementing the Shooting technique, the computations are drawn numerically for the distributions of velocity, thermal variations and species changes for distinct dimensionless parameters such as Hartmann number, buoyancy parameters, porous parameter, local inertial parameter, Prandtl number, viscosity parameter, Eckert number and chemical reaction parameter etc. Also, the numerical computations of flow velocity, temperature and species concentration are illustrated graphically for the important physical parameters.

The magnetic dipole-induced ternary-hybrid nanofluid flow behavior along a vertical and horizontal wall under free, mixed, and forced convection

In the field of nanotechnology research, fluid–nanoparticle interaction is attracting a lot of attention. A wide variety of technological and industrial areas that include convection flows, low-velocity heat exchangers, emergency shut nuclear reactors, exposed solar receivers to wind currents, and fans cooling electronic equipment. The flow of ternary-hybrid nanofluid (NF) due to forced, mixed, and free convection comprising platelet, cylindrical, and spherical shaped nanoparticles is explored in this study. Nonlinear governing equations are changed into ordinary differential equations (ODEs) by employing the proper similarity variables. The numerical outcomes of the reduced equations are attained using a shooting method and the Runge–Kutta–Fehlberg 45 (RKF-45) order. Graphical displays are used to convey the numerical results. It is investigated how the various parameters affect each profile. Results reveal that the velocity for the forced convection case near the surface declines faster than the free and mixed convection case for distinct values of the porosity parameter. The heat transport for the free convection case shows less heat transport than the forced and mixed convection case. The mass transport for the forced convection case shows improved mass transport than the free and mixed convection case for distinct values of chemical reaction rate parameter.

Impacts of chemical reaction, thermal radiation, and heat source/sink on unsteady MHD natural convective flow through an oscillatory infinite vertical plate in porous medium

The main objective of this exploration is to analyze the effects of heat source/sink, chemical reactions, and radiation on the unsteady free convective flow through a porous medium using an infinitely oscillating vertical plate. The Laplace transformation tactics is utilized to solve the governing equations for concentration, energy, and momentum. The simulation results demonstrate that the chemical reaction parameter dwindles both primary and secondary velocities. It has been noted that an upsurge in heat generation (heat source) enhances the temperature field, while a decrease in heat absorption (heat sink) leads to a reduction in the temperature field. Furthermore, the radiation parameter causes a drop in both temperature and velocity patterns. The equation for skin friction is derived and presented graphically, and 3-dimensional surface plots are provided to depict the Nusselt number and Sherwood number. Additionally, graphical illustrations are employed to showcase the influence of various non-dimensional variables on concentration, temperature, and velocity patterns.

Micropolar nanoparticles flow on a stretching/shrinking sheet with multiple slips

The purpose of this paper is to examine the flow of micropolar fluid containing ternary nanoparticles, with multiple slips over a stretching/shrinking sheet. Also, the influences of internal radiation and with the first order chemical reaction are examined to study the fluid properties. Mathematical modeling for the defined problem is framed and yields coupled nonlinear PDEs which are then reduced to nonlinear ODEs by choosing suitable similarity variables. The resulting ODEs are solved by analytical technique and solution is represented as an incomplete gamma function and a hypergeometric function. The regulating parameters, such as Eringen parameter, chemical reaction parameter, inverse Darcy number, Prandtl number and radiation parameter impact are examined for the profiles of velocity, microrotation, energy and concentration of the fluid through graphs. Furthermore, the skin friction drag of the defined flow is also discussed. This investigation reveals the existence of multiple solutions for the case of shrinking and for the case of stretching it shows a unique solution. Also, the tri-hybrid nanofluid flow velocity is found to increase and decrease for the first and second solutions respectively. The velocity, energy and concentration of the flow are found to decrease due to slip conditions.

Impact of activation energy on magneto-bioconvection flow of oxytactic microorganisms with NePCM in complex shaped enclosure considering thermal radiations

This work explores the effect of activation energy on bioconvection flow of oxytactic microorganisms with nano-encapsulated phase change materials in complex shaped enclosure. The inner wavy wall is partially fixed at the constant high temperature. The proposed problem has been modeled first using the conservation laws and then simulated by utilizing finite element method. The discretized system of nonlinear algebraic equation is computed using the Newtons method. The obtained results have been analyzed for the several important controlling parameters. It has been observed that the vortex centers have been established near the adiabatic walls for lower values of Lewis number. The average Sherwood number and density of motile microorganism are the increasing functions of chemical reaction parameter. Moreover, the average Nusselt number declines with rising values of Peclet number.

Geoinformatics is spatial information based on characteristics and analysis regarding spatial data. Water is the main component of human life with clean water, especially drinking water found from various sources, including spring water. Water quality is a global standard as a chemical, physical, and biological parameter. The study aims to determine the potential spring water based on spatial analysis of water quality standards for potential use. The method used to determine the potential utilization of springs using geographic information system analysis. Data is based on the difference in height, slope, and distance from springs to settlements and discharge. Water quality samples are analyzed using mobile and laboratory tests. The result found that physical parameters from five locations, Sirah Citanggulun, Cikerebek, Cijati, Cijati 2, and Galumpit, have good quality to meet the utilization requirements, especially for water designation class. Chemically parameters, water quality, is relatively good based on several parameters such as pH, Nitrite, dissolved iron, and zinc, which do not exceed the required quality standard threshold. The biological parameters, five samples are contaminated by bacteria Escherichia coli and total coliform. Regarding the literature review, this research found that biological contaminants are unsuitable for drinking water, but it is still good to become another used. The research concluded that the spring water in a small village could become potential uses for drinking water based on the parameter of water quality for daily use, especially for drinking water, regarding biological parameters that spring water must be boiled to drink.

Magnetically-driven nanofluid flow over a slippery-bended surface under thermal radiation and higher order chemical reaction

In this paper, nanofluid flow is considered on curved stretching surface under magnetic influence. Realistic velocity slip together with convective boundary condition is imported. The system is also blessed with radiation and higher order chemical reaction. Active and passive controls of nanoparticles are considered and under both boundary conditions the flow analysis is compared. Leading equations of the system is a set of partial differential equations which are transfigured by similarity variable into a set of highly nonlinear ordinary differential equations (ODEs). The system is solved by the Runge–Kutta fourth-order method (RK-4) with shooting technique. The simulation is done by MAPLE-2021 software. Outcomes are portrayed by several graphs and tables and comparison diagram for different conditions is also included. Velocity lines are compared for suction and injection effect but thermal and concentration profiles are compared under active and passive controls of nanoparticles. The velocity profile changed by 16.55% for higher magnetic profile and the mass transfer changed by 3.57% for actively controlled flow under velocity slip parameter. Chemical reaction parameter detained the concentration profile for both active and passive controls but gave lower magnitude for passively controlled flow.

The impact on shelf life of Tulum cheese of modified atmosphere packaging

Tulum cheese is one of the most important conventional fermented dairy products produced in Türkiye. In this study, the effects of modified atmosphere packaging on the microbiological, physicochemical, sensory properties, and shelf life of Tulum cheese were investigated. For this aim, Tulum cheese samples were divided into four groups (B=100% CO2, C =100% N2, D=70% N2+30% CO2, E=75% N2+25% CO2), and the control samples were packaged in the air (A). These samples stored at 4±1°C were analyzed for the microbiological, chemical, and sensory on days 0, 30, 60, 90, 120, 150, 180, 210, and 240. TMAB, LLP, lactic streptococcus, lipolytic microorganisms, proteolytic microorganisms, and yeast-mold counts increased while the counts of coliform group bacteria, Enterobacteriaceae, and Staphylococcus aureus continually decreased in all groups during the storage. During the storage period, the E. coli and sulfate-reducing anaerobic bacteria counts were detected below detectable levels (<1.0 log10 CFU/g) in all groups. Other chemical parameter values increased continuously while pH values continually decreased during the storage in all the groups. It was observed that the total sensory scores of the samples decreased continually during the storage period. However, when the scores of the E group were evaluated within themselves, significant differences were obtained. In conclusion, Tulum cheese samples packaged in MAP showed significant changes in quality, and their shelf life was extended.

Proton Binding Characteristics of Dissolved Organic Matter Extracted from the North Atlantic.

Marine dissolved organic matter (DOM) presents key thermodynamic properties that are not yet fully constrained. Here, we report the distribution of binding sites occupied by protons (i.e., proton affinity spectra) and parametrize the median intrinsic proton binding affinities (log K̅H) and heterogeneities (m), for DOM samples extracted from the North Atlantic. We estimate that 11.4 ± 0.6% of C atoms in the extracted marine DOM have a functional group with a binding site for ionic species. The log K̅H of the most acidic groups was larger (4.01-4.02 ± 0.02) than that observed in DOM from coastal waters (3.82 ± 0.02), while the chemical binding heterogeneity parameter increased with depth to values (m1= 0.666 ± 0.009) ca. 10% higher than those observed in surface open ocean or coastal samples. On the contrary, the log K̅H for the less acidic groups shows a difference between the surface (10.01 ± 0.08) and deep (9.22 ± 0.35) samples. The latter chemical groups were more heterogeneous for marine than for terrestrial DOM, and m2 decreased with depth to values of 0.28 ± 0.03. Binding heterogeneity reflects aromatic carbon compounds' persistence and accumulation in diverse, low-abundance chemical forms, while easily degradable low-affinity groups accumulate more uniformly in the deep ocean.

Influence of temperature dependent heat source/sink on transient MHD free convective flow in an infinite rigid impermeable vertical cylinder with chemical reaction

It is increasingly apparent that the inclusion of mass transfer aspects, together with certain thermal conditions, in the momentum and energy equations governing MHD flows leads to a numbers of real life applications. Keeping this in view, we have attempted an exact analysis of heat and mass transfer aspects in transient hydromagnetic free convective flow of an incompressible viscous fluid through a vertical pipe under an externally applied magnetic field, assuming presence of chemical reaction and heat source/sink. The governing PDEs, which simplify to a set of 3 linear ODEs in the physical set up considered here, have been solved using Laplace transform technique, with solutions for key physical variables presented in the term of Bessel and modified Bessel functions. The influence of governing non-dimensional parameters, namely, Hartmann number, Schmidt number, source/sink parameter, Prandtl number and chemical reaction parameter, has been illustrated on the developing velocity and some concentration profiles. Some important quantities of engineering interest-surface skin friction and volumetric flow rates-have been computed too and analysed. Some notable finding worth mentioning are: (a) heat source presence causes higher fluid velocity as compared to the heat sink; (b) all important surface shear stress can be suitably controlled, among others, by chemical reaction parameter and Schmidt number. The key challenge of this study has been to obtain exact closed-form solutions of the field equations, including cumbersome Laplace inverses. This study finds innovative applications in the emerging fields such as magnetic materials processing, chemical processes, solar energy systems, etc.

Thermal analysis of magnetized Walter's-B fluid with the application of Prabhakar fractional derivative over an exponentially moving inclined plate

The field of fractional calculus communicates with the conversion of regular derivatives to non-local derivatives with non-integer order. This emerging field has various applications, including population models, electrochemistry, signals processing, and optics. Due to the realistic practices of fractional derivatives, this study focuses on the Walter's-B non-Newtonian fluid flow in terms of fractional-based analysis. Through an exponential movable inclined plate, the magnetized unsteady flow behavior of Walter's-B incompressible fluid is examined. The mass and heat transport mechanisms are scrutinized with the association of chemical reaction and heat absorption/generation, respectively. The conversion of constitutive equations to dimensionless equations is accomplished through the application of dimensionless ansatz. The dimensionless equations are explored through the fractional approach of the Prabhakar derivative with the three-parametric Mittag-Leffler function. Both the Laplace transform and Stehfest methodologies are adopted to address equations based on fractional derivative. The consequence of the physical parameters with distinct time intervals on the concentration, flow field, and temperature distribution is physically visualized through graphics. According to the findings of this study, the velocity distribution decreases as fractional parameter values increase. Moreover, the concentration field exhibits a declining behavior with the improved chemical reaction parameter.

MHD nonlinear natural convection from a uniformly moving porous vertical plate with constant heat and mass flux in the presence of thermal radiation, diffusion‐thermo, heat sink, and chemical reaction

AbstractAn attempt has been made to investigate the problem of nonlinear free convection heat and mass transfer flow past an infinite vertical porous plate embedded in a porous medium by taking into account thermal radiation and heat sink with constant heat and mass flux. Transversely oriented and of uniform strength , a magnetic field has been introduced to the fluid area. The nonlinear density variation with temperature as well as concentration are the basis for the current physical situation, which is explained by this mathematical model. Exact solutions are derived for momentum equation, energy equation, and species continuity equation under the relevant boundary conditions. The dimensionless governing equations are analytically solved. The influence of various physical parameters, such as Dufour number, Schmidt number, thermal Grashof number, magnetic parameter, mass Grashof number, heat sink, thermal radiation, Prandtl number, chemical reaction parameter on the flow, and transport characteristic, has been presented graphically and in tabular form. The novelty of the present investigation is that here both constant heat and mass flux at the plate are taken into account in addition to thermal radiation and heat sink. The findings of the mathematical study demonstrate that velocity, temperature, and skin friction intensify with a rise in the Dufour number this is due to the fact that the convection current becomes stronger as the Dufour number rises. Fluid's concentration declines as the Schmidt number grows, or the concentration rises as the mass diffusivity rises. Fluid temperature is enhanced with high thermal diffusivity. Frictional resistance on the plate hikes due to thermal buoyancy force.

Double diffusive MHD squeezing copper water nanofluid flow between parallel plates filled with porous medium and chemical reaction

Purpose This paper aims to explore the double diffusive magneto-hydrodynamic (MHD) squeezed flow of (Cu–water) nanofluid between two analogous plates filled with Darcy porous material in existence of chemical reaction and external magnetic field. Design/methodology/approach The governing nonlinear equations are transformed into ordinary differential equations by means of similarity transforms, and the coupled mass and heat transference equations are resolved analytically with the application of differential transform method (DTM). The effects of different relevant parameters on velocity, temperature and concentration, including the squeeze number, magnetic parameter, Biot number, Darcy number and chemical reaction parameter, are illustrated with figures. In addition, for various parameters, the local skin friction coefficient, local Nusselt number and local Sherwood number are computed and are graphically displayed. Findings It is observed that the squeeze number has a direct relationship with Sherwood number and an inverse relationship with skin friction as Biot number increases. With enhanced Biot numbers, the temperature value increases during both squeeze and non-squeeze moments, but the temperature values are higher for squeeze moments compared to the other case. Practical implications This research has potential applications in various large-scale enterprises that might benefit from increased productivity. Social implications The results are useful to thermal science community. Originality/value Unique and valuable insights are provided by studying the impact of chemical reaction on double diffusive MHD squeezing copper–water nanofluid flow between parallel plates filled with porous medium. In addition, this research has potential applications in various large-scale enterprises that might benefit from increased productivity.

Bioconvection effects on the heat and mass transfer of unsteady MHD blood flow over a permeable artery

The mathematical analysis of blood’s non-Newtonian behavior in the presence of drug nanoparticles and microbes with magnetic and thermal radiation effects is the focus of the current article. The response surface methodology (RSM) is used to conduct a sensitivity study of the bioconvection impacts on the heat and mass transmission rate of the unsteady magnetohydrodynamic blood flow. The physical laws governing unsteady blood flow over stretching blood vessels are mathematically represented as a system of partial differential equations, which are numerically solved using the Fourth Order Runge–Kutta Method in conjunction with the Shooting Technique. Following an analysis of the numerical data, statistical conclusions are drawn on the heat and mass transfer rates. The impact of Brownian motion and thermophoresis factors is discovered to increase blood temperature. Additionally, at the largest Brownian motion factor and maximum thermophoresis effect, the largest heat transfer rate occurs. It is also observed that the lowest mass transfer rates are generated by higher radiation parameter and chemical reaction parameter values. The findings of the study show potential for important applications in therapeutic hypothermia, magnetic therapy, and targeted drug delivery.

Hall effect on unsteady MHD flow along vertical plate with variable temperature and mass diffusion in the presence of porous medium and chemical reaction

The effects of chemical reaction and Hall current on the unsteady magneto hydrodynamic flow along a vertical plate with variable temperature and mass diffusion in the presence of a porous medium is studied hare. The fluid flow model of this paper contains governing partial differential equations of the motion, energy, and diffusion equation. To simplify the analysis, the governing equations are transformed into dimensionless form using non-dimensional variables. The Laplace-transform technique is employed to obtain an exact solution for the flow equations of the MHD model. The results of the analysis are presented using graphical representations of the velocity profiles. With the help of graphs, we discussed the behavior of fluid velocities with different parameters, including the chemical reaction parameter, Hall currents parameter, accelerated parameter, magnetic field parameter, and permeability parameter, and the numerical values of Sherwood number have been tabulated. We found that the values obtained for velocity, concentration and temperature are in concur-rence with the actual flow of the fluid

A comparative analysis of ternary-hybrid nanofluid flows through a stretching cylinder influenced by an induced magnetic field with homogeneous–heterogeneous reactions

This study investigates the flow of three different ternary hybrid nanofluids (THNFs) over a stretching cylinder in a Darcy–Forchheimer permeable medium. The THNFs are made of a mixture of silver, titanium dioxide, and graphene oxide nanoparticles dispersed in water, kerosene oil, and engine oil, separately. The study compares the behavior of the three THNFs and considers the effects of an induced magnetic field, homogenous–heterogeneous reactions, slip boundary conditions, and convective conditions. A bvp4c package of MATLAB software is engaged to find the numerical solution of the modeled equations system and the outcomes are displayed through graphs. It is witnessed that large estimates of the curvature parameter boost the fluid velocity and temperature. Additionally, the surface drag coefficient improves with increasing Darcy–Forchheimer effect. Of the three THNFs, the one with kerosene oil as the base fluid has the best performance. It is witnessed that for the heat transfer rate for engine oil is 19.14% more in comparison to kerosene oil. Similarly, it is 12.83% higher than water. The same is the case for and In addition, the volume fraction of nanoparticles decreases the velocity profile, while the Biot number increases the thermal profile. The chemical reaction parameter decreases the concentration profile. This is justified by comparing the results with previous studies.

An analysis of heat and mass transfer of ternary nanofluid flow over a Riga plate: Newtonian heating

Ternary nanofluids have been show cased to substantially enhance the thermal conductivity and heat transfer attributes of base fluids when compared to ordinary fluids, nanofluids, and hybrid nanofluids. As expected, they are beneficial in thermal management and cooling, and other applications that require effective heat transference. The present analysis deals with the ternary nanofluid flow with heat transmission across Riga plate considering Newtonian heating effect. and are in a base fluid creating a unique combination of that offers various physical and chemical properties. Using appropriate similarity variables, the controlling PDEs are deformed to ODEs, that are analyzed via shooting method and byp4c algorithm. The consequences of several parameters are discussed Graphical on temperature, concentration, and velocity profiles are shown. The outcome of the present analysis shows that in the presence of a Newtonian heating effect, the temperature profile shows better thermal performance than in the absence of the Newtonian heating effect. Additionally, the nature of certain significant engineering coefficients for specific parameters is studied in this article. It is seen that the heat source elevates the rate of heat transfer between a solid surface and fluid flow, whereas opposite trend is observed when the heat sink is considered. Also, the rate of mass transfer is achieved by rising values of the chemical reaction parameter.

Influence of exponential heat source, variable viscosity and shape factor on a hybrid nanofluid flow over a flat plate when thermal radiation and chemical reaction are significant

The significance of hybrid nanofluid flow over a flat plate lies in its ability to enhance heat transfer, improve energy efficiency, enable temperature control, and provide surface protection. For instance, hybrid nanofluids can provide a protective coating on the surface of a flat plate due to the presence of nanoparticles. This coating can offer improved corrosion resistance, erosion resistance, and anti-fouling properties. Consequently, it can extend the lifespan of the flat plate and reduce maintenance requirements. In this study, we examined how several characteristics, such as variable viscosity, chemical reaction, thermal radiation and shape factor of nanoparticles, affect the flow of a hybrid nanofluid (H[Formula: see text]) through a flat plate. The equations required to represent the problem have been turned into a system of nonlinear ordinary differential equations, and this system has been unraveled by means of the bvp4c solver. Outcomes are provided for three instances related to shape factor i.e. Platelet, Cylinder and Spherical. Using Multiple Linear Regression (MLR), we investigated how physical parameters of concern together with friction factor, are affected by a variety of parameters. It is remarked that the fluid’s velocity lessens as the variable viscosity parameter enhances. It is discovered that the temperature profile increases with the rise in exponential heat source parameter ([Formula: see text]). It is discovered that when [Formula: see text], the Nusselt number declines by 0.03588 (Platelet shape), 0.03562 (Cylinder shape), and 0.03489 (Spherical shape). It has been noted that magnetic field parameter (Mg) reduces the coefficient of skin friction. At [Formula: see text], the skin friction coefficient is seen to drop at a rate of 1.15018 (Platelet shape), 1.14871 (Cylinder shape), and 1.14476 (Spherical shape). There is an enhancement in the Sherwood number with the rise in Schmidt number (St) and chemical reaction parameter (Cr). At [Formula: see text] the Sherwood number is seen to rise at a rate of 0.248303 (Platelet shape), 0.248344 (Cylinder shape), and 0.248447 (Spherical shape). Furthermore, it is detected that the fluid’s temperature rises as the thermal radiation parameter enhances and the entropy generation increases as the variable viscosity parameter increases.
