Analysis Effects of Average Value of Convective and Evaporative Heat Transfer Coefficient on Solar Cabinet Dryer for Reduction of Mass of Papad

Abstract: In this research paper, the behavior of heat and mass transfer phenomenon during greenhouse papad drying under forced convection mode has been investigated. Various experiments were performed during the month of April 2020 at SRCEM Banmore, morena (26o 34’13” N 78o 10’48” E). Experimental data obtained for forced convection greenhouse drying of papad were used to determine the constants in the Nusselt number expression by using the simple linear regression analysis and, consequently, the values of convective and evaporative heat transfer coefficients were evaluated. The average values of experimental constants C and n were determined as 0.9714 and 0.0129 respectively. The average values of convective and evaporative heat transfer coefficients were determined as 0.0886 W/m2 oC and 6.7583 W/m2 oC respectively. The experimental error in terms of percentage uncertainty was also evaluated. Keywords: Papad, Papad drying, Heat transfer coefficient, Convective, Evaporative, Forced convection greenhouse

Heat Transport Improvement and Three-Dimensional Rotating Cone Flow of Hybrid-Based Nanofluid

The current research aims to study the mixed convection of a hybrid-based nanofluid consisting of ethylene glycol-water, copper (II) oxide (CuO) and titanium dioxide (TiO2) in a vertical cone. A hybrid base blend model is used to examine the nanofluid’s hydrostatic and thermal behaviors over a diverse range of Reynolds numbers. The application of mixed nanoparticles rather than simple nanoparticles is one of the most imperative things in increasing the heat flow of the fluids. To test such a flow sector, for the very first time, a hybrid-based mixture model was introduced. Also, the mixture framework is a single-phase model formulation, which was used extensively for heat transfer with nanofluids. Comparison of computed values with the experimental values is presented between two models (i.e., the model of a mixture with the model of a single-phase). The natural convection within the liquid phase of phase change material is considered through the liquid fraction dependence of the thermal conductivity. The predicted results of the current model are also compared with the literature; for numerical results, the bvp4c algorithm is used to quantify the effects of nanoparticle volume fraction diffusion on the continuity, momentum, and energy equations using the viscous model for convective heat transfer in nanofluids. Expressions for velocity and temperature fields are presented. Also, the expressions for skin frictions, shear strain, and Nusselt number are obtained. The effects of involved physical parameters (e.g., Prandtl number, angular velocity ratio, buoyancy ratio, and unsteady parameter) are examined through graphs and tables.

Soret radiation and chemical reaction effect on MHD Jeffrey fluid flow past an inclined vertical plate embedded in porous medium

In this manuscript a study of the unsteady magneto-hydrodynamic mixed convection Jeffrey fluid flow over an inclined permeable moving plate in presence of thermal radiation, heat generation, radiation, aligned magnetic field, thermophoresis effect and homogenous chemical reaction, subjected to variable suction has been undertaken. The governing equations are solved by using a regular perturbation technique. The expressions for the distributions of velocity, temperature and species concentration are obtained. With the aid of these, the expressions for skin friction, Nusselt number and Sherwood number also have been derived. The influences of various physical Parameters involved in the problem on the above mentioned quantities are discussed with the help of graphs and tables. From the significant findings, it has been found that the velocity increases with an increase in Jeffrey fluid in the presence of permeability. It shows reverse effects in the case of magnetic parameter, radiation parameter and chemical reaction parameter. Comparisons with previously published work performed and the results are found to be in the excellent agreement.

Solar air heater having multiple V-ribs with Multiple-Symmetric gaps as roughness elements on Absorber-Plate: A parametric study

Conversion of solar energy into thermal energy using solar collectors is the most promising way for itsapplicability. Artificial roughness applied underside of the solar heat-collector is a preferably advantageous technique to enhance the solar air heater performance. In the present study, a comprehensive parametric analysis of the multi-V-ribs-with-symmetric-multi-gaps type of roughness elements (which employed over the heat-collector plate) has been conducted. Two novel roughness parameters (discreteness ratio and aspect ratio) are introduced and their impact is analyzed on thermo-hydraulic performance of the solar air heater (SAH). Moreover, relative roughness width, relative gap width, relative rib-height and relative rib-pitch impact are also assessed. The output parameter (i.e., Nusselt number and friction factor) has been estimated from the experimentally measured data under steady-state conditions. An increment of 6.46 times in Nusselt number along with 5.67 times in friction factor is observed in a comparison to a smooth SAH. The maximum thermo-hydraulic performance parameter for the present investigation is 4.24, which is comparatively higher. The generalized mathematical expressions for Nusselt number and friction factor are developed. The predicted results are found in the deviation of 7.28% and 8.45% for Nusselt number and friction factor.

Delineating impacts of non-uniform wall temperature and concentration on time-dependent radiation-convection of Casson fluid under magnetic field and chemical reaction

Purpose In various kinds of materials processes, heat and mass transfer control in nuclear phenomena, constructing buildings, turbines and electronic circuits, etc., there are numerous problems that cannot be enlightened by uniform wall temperature. To explore such physical phenomena researchers incorporate non-uniform or ramped temperature conditions at the boundary, the purpose of this paper is to achieve the closed-form solution of a time-dependent magnetohydrodynamic (MHD) boundary layer flow with heat and mass transfer of an electrically conducting non-Newtonian Casson fluid toward an infinite vertical plate subject to the ramped temperature and concentration (RTC). The consequences of chemical reaction in the mass equation and thermal radiation in the energy equation are encompassed in this analysis. The flow regime manifests with pertinent physical impacts of the magnetic field, thermal radiation, chemical reaction and heat generation/absorption. A first-order chemical reaction that is proportional to the concentration itself directly is assumed. The Rosseland approximation is adopted to describe the radiative heat flux in the energy equation. Design/methodology/approach The problem is formulated in terms of partial differential equations with the appropriate physical initial and boundary conditions. To make the governing equations dimensionless, some suitable non-dimensional variables are introduced. The resulting non-dimensional equations are solved analytically by applying the Laplace transform method. The mathematical expressions for skin friction, Nusselt number and Sherwood number are calculated and expressed in closed form. Impacts of various associated physical parameters on the pertinent flow quantities, namely, velocity, temperature and concentration profiles, skin friction, Nusselt number and Sherwood number, are demonstrated and analyzed via graphs and tables. Findings Graphical analysis reveals that the boundary layer flow and heat and mass transfer attributes are significantly varied for the embedded physical parameters in the case of constant temperature and concentration (CTC) as compared to RTC. It is worthy to note that the fluid velocity is high with CTC and lower for RTC. Also, the fluid velocity declines with the augmentation of the magnetic parameter. Moreover, growth in thermal radiation leads to a declination in the temperature profile. Practical implications The proposed model has relevance in numerous engineering and technical procedures including industries related to polymers, area of chemical productions, nuclear energy, electronics and aerodynamics. Encouraged by such applications, the present work is undertaken. Originality/value Literature review unveils that sundry studies have been carried out in the presence of uniform wall temperature. Few studies have been conducted by considering non-uniform or ramped wall temperature and concentration. The authors are focused on an analytical investigation of an unsteady MHD boundary layer flow with heat and mass transfer of non-Newtonian Casson fluid past a moving plate subject to the RTC at the plate. Based on the authors’ knowledge, the present study has, so far, not appeared in scientific communications. Obtained analytical solutions are verified by considering particular cases of the published works.

Heat and mass transfer of triple diffusive convection in viscoelastic liquids under internal heat source modulations

AbstractThe influence of sinusoidal (trigonometric cosine [TC]) and nonsinusoidal waveforms (square, sawtooth, and triangular) of internal heat source modulation on triple diffusive convection in viscoelastic liquids is investigated. An Oldroyd‐B type model is taken into account for viscoelastic liquids. Nonlinear analysis is carried out using a truncated representation of the Fourier series. To analyze the heat and mass transfer over a triply diffusive liquid layer, expressions for average Nusselt and average Sherwood numbers are derived using 8‐mode generalized Lorenz equations. The transient behavior of Nusselt and Sherwood numbers is analyzed on different parameters of the problem. From the results, it is found that the internal heat source enhances the heat transfer and diminishes the mass transfer while the heat sink diminishes the heat transfer and enhances the mass transfer. The results for respective waveforms are obtained for each parameter and it is found that the maximum heat and mass transfer occurs due to TC waveform. The limiting cases of viscoelastic liquids (Newtonian, Oldroyd‐B, Maxwell, and Rivlin–Ericksen) have been tabulated and corresponding results for each of the waveforms on heat and mass transfer have been shown.

Investigation on effects of varying geometrical configurations on thermal hydraulics flow in a 3D corrugated pipe

In this numerical investigation, the flow behavior, pressure drop, and heat transfer enhancement for the fluid in a corrugated pipe with varying geometrical configurations arrangements by supporting the computational simulation technique are analyzed. Also, correlations expressions for friction factor (f) and Nusselt number (Nu) with different corrugated geometrical parameters are developed. The numerical modeling is applied using computational fluid dynamics (CFD), and flow field patterns with different structural parameters are predicted. The numerical simulation results are validated with available experimental data. The numerical approach combined with the varying qualitatively and quantitatively analysis are used. The computational investigations are carried out for a different range of Reynolds numbers (Re) with varying corrugated geometrical configurations, including corrugated pipe ratio (PCR) of 20, 40, 60, 80, and 100%, a number of the corrugated ring (NCR) of 2, 3 and 4 as well as the corrugated diameter ring (CDR) of 1, 2 and 3 mm respectively. The outcomes illustrate that as in similar Re number increases, the Nu number increases. When the corrugated geometrical increases, the mixing, and recirculation flow regions start to high rise along the corrugated pipe. Then the flow becomes more undisturbed near and closes to the corrugated rings, and hence the pressure drop (PD), Turbulent kinetic energy (TKE), and vorticity also increase. Moreover, as the PCR increases, the friction factor increases and the f for PCR of 100% is considerably higher than other models. The friction factor for PCR is higher than other models by about 7.05, 24.3, 40.7, and 67.1%. Furthermore, the performance evaluation factor is greater than unity.

Influence of slip condition on transient laminar flow over an infinite vertical plate with ramped temperature in the presence of chemical reaction and thermal radiation

AbstractAn analysis was made using the numerical approach of a transient laminar slip flow over an infinite vertical plate with ramped and constant temperatures in which chemical reaction is involved and thermal radiation had to be considered. Slip conditions have caused much concern because of their broad applicability in industry and chemical engineering. By following the finite element technique, the equation of momentum together with the equations of energy and species was numerically solved. The expressions for skin friction, Nusselt number, and Sherwood number are also derived. The variations in fluid velocity, fluid temperature, and species concentration are displayed graphically whereas numerical values of skin friction, Nusselt number, and Sherwood number are presented in tabular form for various values of the pertinent flow parameters. The findings indicate that the radiation has a noticeable impact to a minor intensity of R and is more apparent in the constant condition than in the ramped condition. Radiation and buoyancy effects produce a strong flow near the plate, which is accelerated by slip. Finally, it is shown logically and mathematically that when two buoyancies are opposite and equal in magnitude with equal solutal and thermal diffusions, the flow should be taken as stationary flow in the absence of radiation and the presence/absence of slip.

Unsteady Couette Flow Past between Two Horizontal Riga Plates with Hall and Ion Slip Effects

Riga plate is the span wise array of electrodes and permanent magnets that creates a plane surface and produced the electromagnetic hydrodynamic fluid behavior and mostly used in industrial processes with fluid flow affairs. In cases where an external application of a magnetic or electric field is required, better flow is obtained by the involvement of the Riga plate. Riga plate acts as an agent to reduce the skin friction and enhance the heat transfer phenomena. It also diminishes the turbulent effects, so that it is possible to get an efficient flow control and it increases the performance of the machine. So the numerical investigation of the unsteady Couette flow with Hall and ion-slip current effects past between two Riga plates has been studied and the numerical solutions are acquired by using explicit finite difference method and estimated results have been gained for several values of the dimensionless parameter such as pressure gradient parameter, Hall and Ion-slip parameters, modified Hartmann number, Prandtl number, and Eckert number. In this article, the importance of the modified Hartmann number on the flow profiles is immense owing to the Riga plate. The expression of skin friction and Nusselt number has been computed and the outcomes of the relevant parameters on various distributions have been sketched and presented as well as graphically.

Numerical modeling on hybrid nanofluid (Fe3O4+MWCNT/H2O) migration considering MHD effect over a porous cylinder.

The free convective hybrid nanofluid (Fe3O4+MWCNT/H2O) magnetized non-Darcy flow over a porous cylinder is examined by considering the effects constant heat source and uniform ambient magnetic field. The developed coupled PDEs (partial differential equations) are numerically solved using the innovative computational technique of control volume finite element method (CVFEM). The impact of increasing strength of medium porousness and Lorentz forces on the hybrid nanofluid flow are presented through contour plots. The variation of the average Nusselt number (Nuave) with the growing medium porosity, buoyancy forces, radiation parameter, and the magnetic field strength is presented through 3-D plots. It is concluded that the enhancing medium porosity, buoyancy forces and radiation parameter augmented the free convective thermal energy flow. The rising magnetic field rises the temperature of the inner wall more drastically at a smaller Darcy number. An analytical expression for Nusselt number (Nuave) is obtained which shows its functional dependence on the pertinent physical parameters. The augmenting Lorentz forces due to the higher estimations of Hartmann retard the hybrid nanoliquid flow and hence enhance the conduction.

Diffusion-thermo and heat source effects on the unsteady radiative MHD boundary layer slip flow past an infinite vertical porous plate

The heat and mass transfer characteristics of the nonlinear, unsteady, radiative MHD boundary layer slip flow of a chemically reacting fluid past an infinite vertical porous plate are taken into account in this study. The effect of physical parameters are accounted for two distinct types of thermal boundary conditions namely prescribed uniform wall temperature thermal boundary condition and prescribed heat flux thermal boundary condition. Exact solution of the governing equations for the fluid velocity, temperature and concentration are obtained by using two term perturbation technique subject to physically appropriate boundary conditions. The expressions of skin friction, Nusselt number and Sherwood number are also derived. The numerical values of fluid velocity, temperature and concentration are displayed graphically whereas those of shear stress, rate of heat transfer and rate of mass transfer at the plate are presented in tabular form for various values of pertinent flow parameters. Results are compared with the literature in the limiting case.

Experimental investigation for heat and flow characteristics of solar air heater having symmetrical gaps in multiple-arc rib pattern as roughness elements

ABSTRACT The working medium is air in a solar air heater (SAH) and because of its low heat-transfer coefficient, SAH results in poor performance. By placing artificial-roughness over the heat-collector plate, the performance of a SAH can be improved significantly. The improvement in thermal and hydraulic performance by providing multiple-arc-rib roughnesses patterns with the gap is discussed and generalized correlations are developed for Nusselt number and friction factor based on results collected from the experimentation (under steady condition). In total seven parameters were considered to study heat transfer and friction characteristics, that is, Reynolds number, rib-pitch, rib-height, number of gaps, arc-attack angle, rib, and gap width. In comparison to smooth collector-plate type of solar air heater, the 5.76 and 6.05 times higher Nusselt number and friction factor obtained in the proposed roughened SAH. Besides this, the developed mathematical expression for Nusselt number and friction factor shows close-fit with the experimental data under the error band of only 10 and 12%, respectively.

Radiation effect on free convection flow between oscillating parallel plates with mass diffusion

This study investigates radiation effect on unsteady oscillatory free convection between two parallel plates with mass diffusion. Appropriate non-dimensional variables are used to reduce the dimensional governing equations to dimensionless equation along with imposed initial and boundary conditions. The solutions for velocity, temperature, and concentration profiles are obtained by using Laplace transform method. To illustrate the behavior of the fluid flow, graphical results are presented with influenced of Schmidt number, Prandtl number, radiation parameter, oscillating parameter, Grashof, and mass Grashof number. The corresponding expressions for skin friction, Nusselt number, and Sherwood number are also calculated. It is observed that increasing radiation parameter, Prandtl, and Schmidt number will increase the Nusselt number but the skin friction will be reduced.

Unsteady MHD natural convection flow of Casson fluid incorporating thermal radiative flux and heat injection/suction mechanism under variable wall conditions

Unsteady magnetohydrodynamic flow of Casson fluid over an infinite vertical plate is examined under ramped temperature and velocity conditions at the wall. Thermal radiation flux and heat injection/suction terms are also incorporated in the energy equation. The electrically conducting fluid is flowing through a porous material and these phenomena are governed by partial differential equations. After employing some adequate dimensionless variables, the solutions are evaluated by dint of Laplace transform. In addition, the physical contribution of substantial parameters such as Grashof number, radiation parameter, heat injection/suction parameter, porosity parameter, Prandtl number, and magnetic parameter is appropriately elucidated with the aid of graphical and tabular illustrations. The expressions for skin friction and Nusselt number are also derived to observe wall shear stress and rate of heat transfer. A graphical comparison between solutions corresponding to ramped and constant conditions at the wall is also provided. It is observed that graphs of the solutions computed under constant conditions are always superior with respect to graphs of ramped conditions. The magnetic field decelerates the flow, whereas the radiative flux leads to an upsurge in the flow. Furthermore, the shear stress is a decreasing function of the magnetic parameter.

Couette flow of viscoelastic dusty fluid in a rotating frame along with the heat transfer

Viscoelastic fluid is an advanced fluid which exhibits both elastic and viscous properties. Whereas rotation of viscoelastic fluid is a very complex phenomenon and has an immense amount of applications in engineering and product making industries. Due to various applications in real life researchers are working to understand the rheology of viscoelastic fluids. Viscoelastic dusty fluids are used in gas cooling systems. In nuclear reactors, dusty fluids are used to lower the temperature of the system. Such fluids are also used in centrifugal separators, which separate solid particles from the liquid state, etc. Therefore, in the present study, viscoelastic dusty fluid is analyzed. More precisely free convective Couette flow under the influence of the transversely applied uniform magnetic field in a rotating frame is considered. The subject fluid is driven by the sine oscillations of the upper plate along with the effect of free convection. Due to rotation, the fluid and dust particles have complex velocities which is the sum of primary velocity and secondary velocity. The flow regime is modeled in terms of partial differential equations. To non-dimensionalize the system of governing equations, dimensionless variables have been derived through Buckingham-Pi theorem. The system of partial differential equations is solved through assumed periodic solutions (Poincare-Light Hill Technique). The expressions for skin friction (shear stresses at y = 0) and Nusselt number (the rate of heat transfer) are also calculated. Moreover, parametric influence on Nusselt number, and velocity profile of the fluid and the dust particles, is discussed. It is observed that increase in rotation parameter η causes retardation in the velocity of dust particles and the fluid. This is due to the fact that the increase in η enhances the Coriolis forces that are in fact inertial forces, causing a retardation in the velocity of the fluid phase and the dust phase.

Heat and mass transfer effect of a Magnetohydrodynamic Casson fluid flow in the presence of inclined plate

T he key purpose of this paper is to study the convection of a transient state in the flow of MHD Casson fluid over an inclined layer. In addition, the influence of the magnetic field, Dufour effects and heat suction / injection through porous medium are considered in the present analysis. By the Laplace transformation process, the analytical solutions of governing equations are established. By using the particular solution of fluid temperature and species concentration, the expressions for Nusselt number and Sherwood number are also premeditated. The variations in fluid velocity, fluid temperature, species concentration, Nusselt number and Sherwood number are shown graphically for different values of pertinent flow parameters.It is noted that with an increase in the Dufour number, the axial velocity decreases and it is also noted that the concentration of the species decreases with an increase in the Dufour number.The velocity decreases as all the cases of cooling and heating of the porous inclined plate raise the suction parameter.

The impulsively started plate with variable temperature and mass diffusion is considered. The dimensionless momentum equation coupled with the energy and mass diffusion equations are analytically solved using the closed analytical method. Expressions for velocity, temperature and concentration fields are obtained. They satisfy all imposed initial and boundary conditions and can be reduced, as special cases, to some known solutions from the literature. Expressions for skin friction, Nusselt number and Sherwood number are also obtained. Finally, the effects of parameters on velocity, temperature and concentration profiles and skin friction coefficient are graphically displayed.

Analysis and modeling of fractional electro-osmotic ramped flow of chemically reactive and heat absorptive/generative Walters'B fluid with ramped heat and mass transfer rates

In this contemporary era, fractional derivatives are widely used for the development of mathematical models to precisely describe the dynamics of real-world physical processes. In the field of fluid mechanics, analysis of thermal performance and flow behavior of non-Newtonian fluids is a topic of interest for a variety of researchers due to their significant applications in several industries, engineering operations, devices, and thermal equipment. The primary focus of this article is to investigate the effectiveness of jointly imposed time-controlled (ramped) boundary conditions in the electro-osmotic flow of a chemically reactive and radiative Walters' B fluid along with concentration and energy distributions. In Particular, the concept of using piece-wise time-dependent mass, motion, and energy conditions simultaneously for any non-Newtonian fluid is extensively explored in this work. The flow is developed due to the motion of the bounding vertical wall, which is suspended in a porous material subject to heat injection/absorption and uniform magnetic influences. Atangana-Baleanu derivative of order $ \psi $ is incorporated to establish the fractional form of ordinary modeled equations. Laplace transform method is adapted in light of some unit-less quantities to procure the exact solutions of the under observation model. Several graphical delineations are produced to comprehensively analyze the key characteristics of many physical and thermal parameters. To highlight the significance of operating surface conditions, solutions are compared for time-dependent and constant boundary conditions in every graph. Furthermore, the role of the fractional parameter, time-dependent conditions, and different other involved parameters in heat transfer, mass transfer, and flow rates is characterized by determining the expressions for Nusselt and Sherwood number and coefficient of skin friction. The numerical outcomes are organized in several tables to deeply scrutinize the noteworthy variations in the behavior of the aforementioned physical quantities. The graphical study reveals that the parameter $ E_s $ accounting for electro-osmotic effects decelerates the flow of fluid. At the atomic level, such electro-osmotic flows are useful in the separation processes of the liquids. The fractional parameter $ \psi $ attenuates thicknesses of boundary layers for the evolution of time $ t $ but, it exhibits an opposite role for smaller values of $ t $. It is also noted that the direct correspondence between velocity and time at the boundary for time duration $ t

Insight into the significance of ramped wall temperature and ramped surface concentration: The case of Casson fluid flow on an inclined Riga plate with heat absorption and chemical reaction

Abstract The importance of heat absorption and chemical reactions and their impact in engineering is increasingly appreciated. However, little is known about the effect of chemical reaction and heat absorption of ramped wall temperature and ramped surface concentration on a Casson fluid flow over a rapidly accelerated inclined Riga plate. The aim of the study, among other findings along an inclined Riga plate, is to address the impact of heat sink and chemical reaction over a ramped temperature and ramped surface concentration. By introducing relevant similarity variables, the dimensional governing equations are non-dimensionalized and parameterized. After that, the derived parameterized governing equations are solved analytically using the Laplace transform method. Graphs are used to discuss and analyse the effects of various physical parameters on momentum, energy, and concentration. The latest findings are verified by comparing them to previous results. Tables are also used to determine skin friction, Nusselt number, and Sherwood number expressions. Comparatively, it's worth noting that chemical reaction, Casson, and heat absorption parameters tend to escalate Skin friction for both ramped temperature and ramped surface concentration. Moreso, an increase in the chemical reaction and heat absorption parameters induces a decrease in the momentum distribution.

MHD Maxwell Fluid with Heat Transfer Analysis under Ramp Velocity and Ramp Temperature Subject to Non-Integer Differentiable Operators

The main focus of this study is to investigate the impact of heat generation/absorption with ramp velocity and ramp temperature on magnetohydrodynamic (MHD) time-dependent Maxwell fluid over an unbounded plate embedded in a permeable medium. Non-dimensional parameters along with Laplace transformation and inversion algorithms are used to find the solution of shear stress, energy, and velocity profile. Recently, new fractional differential operators are used to define ramped temperature and ramped velocity. The obtained analytical solutions are plotted for different values of emerging parameters. Fractional time derivatives are used to analyze the impact of fractional parameters (memory effect) on the dynamics of the fluid. While making a comparison, it is observed that the fractional-order model is best to explain the memory effect as compared to classical models. Our results suggest that the velocity profile decrease by increasing the effective Prandtl number. The existence of an effective Prandtl number may reflect the control of the thickness of momentum and enlargement of thermal conductivity. The incremental value of the M is observed for a decrease in the velocity field, which reflects to control resistive force. Further, it is noted that the Atangana-Baleanu derivative in Caputo sense (ABC) is the best to highlight the dynamics of the fluid. The influence of pertinent parameters is analyzed graphically for velocity and energy profile. Expressions for skin friction and Nusselt number are also derived for fractional differential operators.
