Effect of NP shapes on Fe3O4 – Ag/kerosene and Fe3O4 – Ag/water hybrid nanofluid flow in suction/injection process with nonlinear-thermal-radiation and slip condition; Hamilton and Crosser's model

This study examines the flow and thermal properties of water and kerosene hybrid nanofluids in a horizontal microchannel. The effects of nonlinear thermal radiation, heat source coefficient, convective and slip boundary conditions on nanofluids in a microchannel have been studied. The impact of different nanoparticle shape factors on the temperature of nanofluids has also been analysed. The governing partial differential equations have been transformed in to ordinary differential equations using dimensionless terms. In the next step, the corresponding ordinary differential equations have been cracked using the RKF45 numerical approach, and the particles shape factor on dimensionless velocity and energy fields for hybrid nanofluid then reported. The results revealed that the spherical and lamina shape factors for both water and kerosene hybrid nanofluid differ the most, the water-based hybrid nanofluid has a higher velocity than the kerosene-based hybrid nanofluid, the thermal energy of both water and kerosene-based hybrid nanofluid was higher in the lower channel plate than the upper channel plate, flow rate falls near the lower channel wall and increases towards the upper channel wall as Reynolds number increases. Thermal energy and entropy generation decrease as the temperature parameter rises.

Analysis of dust diffusion from a self-propelled peanut combine using computational fluid dynamics

Self-propelled peanut combines can significantly improve the production efficiency of peanut harvesting. However, a large quantity of dust is discharged from peanut combines, leading to detrimental environmental changes. To evaluate the diffusion and distribution of dust from a peanut combine, dust discharged from a combine was sampled using an integrated atmospheric sampler that enabled laboratory measurements of dust concentration, particle size distribution, density, and shape factors. A 3D computational fluid dynamics (CFD) model that coupled dust particles and the atmospheric flow was established. The simulation model was verified by comparing the simulated data with the measured dust concentrations on farm. The relationship between the dust discharge factors and the spatial distribution of the dust concentration was analysed using the CFD model. The results showed that an increase in the angle between the dust outlet and the ground increases both the rate of dust deposition and the dust concentration near the combine. By contrast, a reduction in the dust outlet diameter decreased the dust concentration near the combine and rate of dust deposition. Moreover, the spatial dust concentration distribution and the dust concentration discharged from the dust outlet of the combine exhibited a linear relationship. This study provides a reference for the formulation and evaluation of dust suppression schemes for self-propelled peanut combines. • Self-propelled peanut combines improve peanut harvesting production efficiency. • Discharged dust emitted from self-propelled peanut combine measured. • Dust distribution modelled via computational fluid dynamics. • Reference data provided for dust suppression strategies. • Modelling method could be extended to other farm machinery.

Numerical Simulation of Non-Spherical Submicron Particle Acceleration and Focusing in a Converging–Diverging Micronozzle

Submicron particles transported by a Laval-type micronozzle are widely used in micro- and nano-electromechanical systems for the aerodynamic scheme of particle acceleration and focusing. In this paper, the Euler–Lagrangian method is utilized to numerically study non-spherical submicron particle diffusion in a converging–diverging micronozzle flow field. The influence of particle density and shape factor on the focusing process is discussed. The numerical simulation shows how submicron particle transporting with varying shape factors and particle density results in different particle velocities, trajectories and focusing in a micronozzle flow field. The particle with a larger shape factor or larger density exhibits a stronger aerodynamic focusing effect in a supersonic flow field through the nozzle. In the intersection process, as the particle size increases, the position of the particle trajectory intersection moves towards the throat at first and then it moves towards the nozzle outlet. Moreover, the influence of the thermophoretic force of the submicron particle on the aerodynamic focusing can be ignored. The results will be beneficial in technological applications, such as micro-thrusters, microfabrication and micro cold spray.

Study of physicochemical characteristics of calcium hydroxyapatite «Kalident Powder 100» in the development of dental medicine

Despite the development of the dental industry, the prevalence of dental hypersensitivity does not decrease but increases at a progressive rate. Given the above, the subject of our research was the development of dental medicinal films with micronized calcium hydroxyapatite under the trade name «Kalident Powder 100» (Kalichem, Italy) for the treatment of dental hyperesthesia and caries prevention. To establish the optimal method of calcium hydroxyapatite introduction into the dental film, it was necessary to study the influence of different dispersion mediums on the physicochemical characteristics of the substance under study.
 Purified water, ethyl alcohol 96%, polysorbate 80, glycerol, polyethylene oxide-400, propylene glycol, sunflower oil, vaseline oil were used as dispersion medium in the studies. Research of physico-chemical characteristics was performed both for the substance «Kalident Powder 100» separately and for its mixtures with the studied liquids and their combinations (in a ratio of 1:1). The following physico-chemical characteristics have been determined: disperse and diffraction analysis of particle size distribution, morphological description, linear dimensions, shape factor, volume coefficient, Martin and Ferret diameters, wettability.
 The results of crystallographic and disperse analysis have revealed the polydispersity of the substance «Kalident Powder 100» and its high ability to agglomerate, which may adversely affect the homogeneity of its distribution in the dental medicinal product. A study of the effect of different dispersion medium on the physicochemical characteristics of calcium hydroxyapatite has shown a positive effect of hydrophilic liquids on the wettability of powder particles, changes in their shape, size, and distribution in the studied samples. It has been established that the combination of the substance «Kalident Powder 100» with combined solvent systems containing purified water, polysorbate 80, glycerol, and PEO-400, allows achieving optimal shape and particle size of calcium hydroxyapatite with their uniform distribution throughout the liquid, which is also confirmed by the results of laser diffraction. The obtained results will be used in further research on the development of dental medicinal film.

A comparative study on effective density, shape factor, and volatile mixing of non-spherical particles using tandem aerodynamic diameter, mobility diameter, and mass measurements

Combustion-generated particles are typically non-spherical (soot aggregates) and sometimes mixed with organic compounds (e.g. in vehicle emissions). The effective density, dynamic shape factor, and volatile mixing of particles are widely studied using aerosol instruments that measure the particle mobility diameter, aerodynamic diameter, and mass. In theory, any of these three physical properties can be obtained from a combination of the other two. In the present study, a tandem arrangement of aerodynamic aerosol classifier (AAC; measuring aerodynamic diameter), differential mobility analyzer (DMA; measuring mobility diameter), optional catalytic stripper (CS), and centrifugal particle mass analyzer (CPMA; measuring particle mass) was used to study the effective density, dynamic shape factor, and volatile mixing of non-spherical non-homogenous particles. In terms of mass, the vast majority of the particles were purely semi-volatile mixed with soot with and without semi-volatile coating. The effective density of polydisperse non-stripped particles was relatively constant (indicating nearly spherical particles), while that of polydisperse stripped particles decreased from ∼1200 to ∼800 kg/m3 as the particle size increased (indicating a compact structure). The effective density of monodisperse particles, measured by DMA-CPMA, AAC-DMA, and AAC-CPMA methods, was consistent within the measurement uncertainty; however, the latter method had larger discrepancy with the other two methods, particularly for non-spherical particles. The dynamic shape factor, measured by AAC-CPMA and DMA-CPMA methods, increased with the mobility diameter, a trend also supported by electron micrographs. The volatile mass fraction of particles decreased as their mobility diameter increased, with smaller particles having volatile mass fraction of ∼20%. This result was further confirmed by chemical characterization of size-selected particles, proving the robustness of online aerosol measurements.

Terminal velocity and drag coefficient models for disc-shaped particles based on the imaging experiment

Terminal velocity and drag coefficient are the core parameters of particle motion, but their predictive models and measuring methods have rarely been focused. In this work, terminal velocity and drag coefficient models for disc-shaped particles are proposed based on the imaging experiment. Experimental devices include particle sedimentation and video image acquisition systems. A total of 120 disc-shaped particles sedimentation are investigated. Results show that terminal velocity closely relates to the shape, size and density of the particles. Thus, particle shape factors should be considered in the drag coefficient model. The proposed models fitted by the LM + UGO optimization algorithm, have more accuracy and stability than the published models. The present study is applicable for the disc-shaped particles in the ranges of sphericity φ = 0.56–0.77, flatness ratio da /dv = 0.65–1.21, circularity ψ = 0.59–1, and Reynolds number Re = 323–10,800. Furthermore, the imaging measurement method can be extended to other non-spherical particles.

Effects of grinding time on morphology and collectorless flotation of coal particles

The impact of particle shape and surface properties has been mainly overlooked in the literature for different mineral systems. In this study, to investigate the effects of morphological variations, samples of clean coal particles (−0.212 + 0.075 mm) were used and the flotation experimental in a batch condition (2 L Denver cell) were conducted in the absence of collectors by keeping the particle size constant. Binocular microscopic images were used to determine the shape factors of coal particles. A dry ball milling process was carried out as a function of grinding time (60–960 s) and representative samples were taken for determining both shape and floatability of particles. Further, particle-bubble attachment, zeta potential, roundness, surface roughness values and flotation kinetics were measured. It was indicated that by increasing milling duration from 60 s to 960 s, the roundness and roughness increased from 0.792 to 0.809 and 23 nm to 57 nm, respectively. This led to increasing flotation rate constant from 0.4482 ± 0.02 to 0.4856 ± 0.03 1/min. In addition, the theoretical calculations for energy barrier showed that upon increasing the roughness degree from 0 to 57 nm, the energy barrier significantly decreased from 2.79E-16 to 6.51E-17 J/m2, which also proved our findings from a theoretical point of view. Thus, it was finally concluded that the more the roughness, the higher the flotation kinetics and the lower the energy barrier.

Influence of tree species and machine settings on chip quality and specific energy consumption of a stationary drum chipper

Chipper fine tuning, i. e. the selection of suitable feedstocks and machine settings for comminution, might help to optimize wood chip production in terms of chip quality and energy efficiency. A total of 46 wood chip samples were produced with an electrically powered stationary drum chipper. Feedstocks derived from small diameter stem wood (Ø < 12 cm) of six different coniferous and broad-leaf tree species. Chipper settings varied in knife sharpness, screen mesh size and infeed-roller speed. Wood chip properties were determined following ISO standards for solid biofuels. Furthermore, image analysis allowed for highly detailed information on particle size and particle shape. Classification of wood chips followed ISO 17225-4. Throughput rate and energy consumption during chipping were related to volume and dry matter of the bulk material. Results indicate that chipping with narrow chipper screens reduced the share of coarse particles while chipping with blunt knives significantly increased the share of fine particles, the maximal particle length, the length to width ratio of particles and their particle shape factor. Specific electrical energy consumption during chipping strongly increased from approx. 4.2 kWh t−1 (d. b.) up to 12.8 kWh t−1 (d. b.) when blunt knives were applied. Overall, approx. 96% of all samples could be classified as “graded wood chips” according to ISO 17225-4 but only chipping with sharp knives and a narrow chipper screen (40 × 40 mm) allowed for the consequent production of high-quality wood chips of the particle size class P31s.

Evaluation of Fuel Quality, Throughput Rate and Energy Consumption During Non-Industrial Wood Chip Production with Three PTO Driven Chippers

Physical wood chip quality is essential for failure-free and low emission combustion in small-scale boilers ≤100 kW. In Bavaria, these furnaces are often operated by farmers or private forest owners that produce their own fuels using small to medium sized PTO-driven chippers. As secondary fuel processing steps such as industrial screening are usually too expensive for private forest owners, the selection of suitable raw materials and process parameters to directly produce high quality fuels during chipping are deemed especially relevant for this user group. In the present study, three commonly used small-scale chippers ≤150 kW, i. e. a drum, a spiral and a disc chipper where evaluated in terms of fuel quality, throughput rate and energy consumption during wood chip production. Chipping was done using stem wood of European beech and Norway spruce. Machine settings were the ones recommended by the chipper manufactures for the production of high quality fuels. Additional chipping variants included the use of different raw materials such as crown residues of European willow and varying machine settings including blunt knives, increasing spiral cut length, large screen mesh sizes or increased PTO speeds. Representive wood chip samples were taken after each trial and analysed in their physical fuel properties according to international standards for solid biofuels but also using a continuously measuring image analysis device to determine particle length and particle shape. For all three mobile chippers, wood chips with the particle size class »P31s« according to the revised ISO 17225-4:2021 could be produced when stem wood was used as assortment. Fine content of chips, i. e. particles ≤3.15 mm, was lowest for the spiral chipper and increased for the drum and disc chipper, especially when blunt knives or narrow screen meshes were used for chipping. At the same time, blunt knives increased the particle shape factor (PSF) of the bulk materials indicating a rather broken particle surface structure compared to clean cut particles. Throughput rate decreased and energy consumption increased when fuels with small particle size were produced, e. g. when narrow screen meshes or narrow chipping spirals were applied. This trend was particularly pronounced when blunt knives were used for chipping due to grinding of the material. All three chippers could be recommended for the production of high quality fuels for small-scale boilers when suitable machine settings and raw materials are applied for chipping.

Development and validation of an analytical method for tensile strength determination of fibrous bulk solids

The increasing significance of products consisting of elongated particles or fibres along with a lack of understanding flow properties of fibrous bulk solids in processes urge for appropriate test procedures.Therefore, a tensile tester was designed with respect to the special needs in terms of test techniques of those bulk solids. The procedure of tensile strength determination was tested with regard to several possible influencing factors. Following from that, the manner of filling and filling height were identified to have the greatest influence on results. Furthermore, it is shown that the developed load system is capable of improving the repeatability of test results for fibrous bulk solids.Based on the derived standard procedure, systematic tests were carried out on beech and spruce chips in three different fractions each as well as model materials such as polypropylene fibres and differently sized bunches of glass fibres. The biomass materials have been characterised by dynamic image analysis prior to and after experiments resulting in particle size and shape factor distributions. It is found that tensile strength is affected by particle shape, size, roughness and interparticle contact area.

Properties of biomass powders resulting from the fine comminution of lignocellulosic feedstocks by three types of ball-mill set-up

Background: Lignocellulosic biomass has many functionalities that hold huge potential for material, energy or chemistry applications. To support advanced applications, the biomass must be milled into ultrafine powder to increase reactivity. This milling unit operation needs to be fully mastered to deliver high-quality standard end-products. Here we studied the relationship between the characteristics of the starting lignocellulosic plant material and the properties of the resulting ultrafine powder in different ball-mill process routes. Methods: Two lignocellulosic biomasses (pine bark and wheat straw) with contrasted compositional and mechanical properties were milled using three ball-mill set-ups delivering different balances of impact force and attrition force. The resulting powders were analysed for particle characteristics (size, agglomeration extent, shape) and powder flow properties (compressibility, cohesion) using a dynamic powder rheometer. Results: Pine bark is more amenable to a fast particle size reduction than the fibrous wheat straw. The resulting pine bark powders appear less compressible but much more cohesive than the straw powders due to particle shape, density and composition factors. The mill set-up working by attrition as dominant mechanical force (vibratory ball mill) produced a mix of large, elongated particles and higher amounts of fines as it acts mainly by erosion, the resulting powder being more prone to agglomerate due to the abundance of fines. The mill set-up working by impact as dominant mechanical force (rotary ball mill) produced more evenly distributed particle sizes and shapes. The resulting powder is less prone to agglomerate due to a preferential fragmentation mechanism. Conclusions: The attrition-dominant mill yields powders with dispersed particle sizes and shapes and the poorest flow properties, while the impact-dominant mill yields more agglomeration-prone powders. The mill set-up working with impact and attrition as concomitant mechanical forces (stirred ball mill) produces powders with better reactivity and flow properties compared to rotary and vibratory mills.

Modeling of nanoparticle fluid microscopic plugging effect on horizontal and vertical wellbore of shale gas

Shale gas is an important part of realizing the modern multi-energy system as a kind of unconventional energy with huge reserves for human energy needs. Adding nanomaterials to plug shale pores is an effective method to improve shale gas development. However, the dynamic migration of nanoparticles in shale pores, the time-space process of plugging, and the mapping relationship between permeability under different wellbore conditions are unclear. In this paper, a fluid-solid coupling nano-blocking model based on pore characteristics, fluid physical properties, and discrete element parameters is established considering the nano-scale effects. In order to ensure the rationality of the nanoparticle force, codes were written to modify the flow resistance. Pore ratio with perpendicular and parallel to shale bedding and channel bending degree model is established, and their rationality is verified through experiments. Particle concentration, size, particle release mode and shape factors for plugging efficiency were discussed with different wellbore conditions. Results indicate the plugging gap between horizontal and vertical wells narrowed by 43.76% as particles increased from 1 wt% to 5 wt%. Increasing the particle size has a greater impact on plugging efficiency of vertical well pores. In the multi-scale particle release mode, the particle plugging effect is increased by 90.44% and 94.22% compared with vertical and horizontal wells, respectively. The research results can provide nano plugging solutions in drilling fluid for shale gas development.

Fluidization behavior of graphitized glassy particles in a fluidized carbon bed cooling process for investment casting

Fluidized Carbon Bed Cooling (FCBC) is an innovative investment casting process for directional solidification of superalloy components. It takes advantage of a fluidized bed with a base of small glassy carbon beads for cooling and other low-density particles that form an insulating layer by floating to the bed surface. This so-called “Dynamic Baffle” protects the fluidized bed from the direct heat input from the high-temperature heating zone and provides the basis for an improved bed microstructure. The prerequisites for a stable casting process are stable fluidization conditions where neither collapse of the bed nor particle blow out at excessive bubble formation occur.This work aimed to investigate the fluidization behavior of spherical carbon bed material in argon and air at temperatures between 20 to 350 °C. Systematic studies at reduced pressures using the FCBC prototype device were performed to understand the stable fluidization conditions at all stages of the investment casting process. The particle shape factor and size distribution characterization and the measurement of the powder’s minimum fluidization velocity and bed voidage show that this material can be fully utilized as a cooling and buoyancy medium during the FCBC process.

Numerical simulation of pneumatic conveying characteristics of micron particles in horizontal pipe

In this paper, a mathematical model for the pneumatic transport of micron silica particles in the dust removal pipeline is established, and the gas-solid two-phase flow in the pipeline is numerically simulated. This paper is mainly based on the FLUENT fluid simulation module in ANSYS WORKBENCH to simulate the motion behavior of particles in the pipeline, and obtained the penetration rate (particle deposition rate in pneumatic conveying) of silica particles in the horizontal straight pipe under different gas flow rates. In the numerical simulation, the influence of particle diameter, shape, lift and other factors on silica particles was considered. Under a large number of simulation conditions, the movement laws of micron silica particles in horizontal pipe pneumatic transport were obtained, and the influence of the above factors on the movement laws of the particles were determined.

Impact of the whey protein/casein ratio on the reconstitution and flow properties of spray-dried dairy protein powders

This study focuses on the impact of the whey protein/casein ratio (100/0, 79/21, 57/43, 35/65, and 12/88) on the physicochemical and functional characteristics of dairy protein powders. Spray-drying was performed in the following conditions: 200 °C inlet air temperature and 85 °C outlet air temperature. Physicochemical properties (particle size distribution, shape factors, moisture content, and water activity) of spray-dried powders were characterized to explain their reconstitutability, on the basis of the wettability, dispersibility, solubility indices, and their flowability, evaluated with the FT4 powder rheometer.Reconstitutability analyses revealed that solubility of dairy protein powders linearly varied with the whey protein/casein ratio. It was also highlighted that wettability and dispersibility determined with the standard methods were not relevant to evaluate the reconstitutability of investigated powders: in fact, all studied powders were non-wettable and non-dispersible according to the milk powder standards. This was likely to result from the low median particle size (between 10 and 30 μm) of powders produced by spray-drying at pilot-scale.The flowability of powders was evaluated as poor due to a high level of interparticular cohesion, which mainly derived from their small median particle size. The impact of protein composition on flowability was not statistically significant, despite a shape modification reflected by a decrease in particle sphericity upon casein proportion increase. The small particle size, leading to poor flow properties, overwhelmed the impact the whey protein/casein ratio, but a slight improvement of the flowability and a reduction of cohesion was induced by higher proportions of whey proteins.

Photogrammetry based computational fluid dynamics of erosion of sand particles in water pipeline: Dynamic shape factors of 3D particles and minimization of erosion activity

Extraction and delivery of raw materials in engineering industries are inevitably polluted with sand particles that caused several flow assurance problems. Besides, designing a pipeline and estimating sand erosion is very complex in a multiphase flow due to several important factors needed to be considered, such as impact velocity, impact angle, size of particle, shape of particle, properties of particle, and properties of the target material. In this work, a modified E/CRC erosion model was developed to address the shape randomness in sand particles distribution. The photogrammetry technique was adopted to digitize sand particles into 3D models within the range of 400–500 μm. After quantitative and qualitative analysis, a database of shape factor for different spherical and roundness of sand particles was tabulated. Meanwhile, a high-fidelity simulation of a 90-degree elbow pipeline was conducted using the CFD-DEM method. Hydrodynamic characteristics of liquid flow, sand particle trajectories, the sensitivity of velocity, shape factor, and flow rate were comprehensively explored. Modification of the particle shape factor based on the generated database from photogrammetry resulted in overestimated erosion rate of the original E/CRC model with 124.4% accuracy improvement in predicting erosion rate on pipe bend at different collision angles. Lastly, through response surface methodology (RSM), a flow threshold condition was established to achieve minimum erosion damage.

New hydraulic insights into rapid sand filter bed backwashing using the Carman–Kozeny model

Fluid flow through a bed of solid particles is an important process that occurs in full-scale water treatment operations. The Carman–Kozeny model remains highly popular for estimating the resistance across the bed. It is common practice to use particle shape factors in fixed bed state to match the predicted drag coefficient with experimentally obtained drag coefficients. In fluidised state, however, where the same particles are considered, this particle shape factor is usually simply omitted from the model without providing appropriate reasoning. In this research, it is shown that a shape factor is not a constant particle property but is dependent on the fluid properties as well. This dynamic shape factor for irregularly shaped grains increases from approximately 0.6 to 1.0 in fluidised state.We found that unstable packed beds in moderate up-flow conditions are pseudo-fixed and in a setting state. This results in a decreasing bed voidage and simultaneously in a decreasing drag coefficient, which seems quite contradictory. This can be explained by the collapse of local channels in the bed, leading to a more uniform flow distribution through the bed and improving the available surface for flow-through. Our experimental measurements show that the drag coefficient decreases considerably in the laminar and transition regions. This is most likely caused by particle orientation, realignment and rearrangement in particles’ packing position.A thorough hydraulic analysis shows that up-flow filtration in rapid sand filters under backwash conditions causes the particle bed to collapse almost imperceptibly. In addition, an improved expression of the drag coefficient demonstrated that the Carman–Kozeny model constant, however often assumed to be constant, is in fact not constant for increasing flow rates. Furthermore, we propose a new pseudo-3D image analysis for particles with an irregular shape. In this way, we can explain the successful method using optimisation of the extended terminal sub-fluidisation wash (ETSW) filter backwashing procedure, in which turbidity and peaks in the number of particles are reduced with a positive effect on water quality.

A gradation-dependent particle shape factor for characterizing small-strain shear modulus of sand-gravel mixtures

In this study, a series of shear wave velocity tests were conducted on two types of sand-gravel mixtures with a wide range of particle size distributions. The effect of the particle shape on the small-strain shear modulus (Gmax) was investigated using a customized, large-scale triaxial apparatus. The results showed that Gmax increases with the decrease in particle roundness when the uniformity coefficient (Cu) is less than a certain value. However, this increasing trend gradually flattens with the further increase of Cu. Thus, the effect of particle shape on the Gmax varies with the particle gradation. The performances of six relationships proposed in the literature for predicting Gmax were compared and evaluated in terms of their predictive capabilities. An empirical Gmax model based on the Hardin and Black equation was proposed by including a Fourier-based shape factor modified by Cu. The model can characterize the difference in the variation of Gmax with Cu due to different particle shapes and was thereafter validated. Furthermore, the model serves as a reference guide for estimating the Gmax of soils with various particle size distributions through their particle characteristics.

Keller box study for inclined magnetically driven Casson nanofluid over a stretching sheet: single phase model

The current analysis signifies the Casson nanofluid stream with inclined magnetohydrodynamics, viscous dissipation, joule heating, thermal radiation, particle shape factor effects over a moving flat horizontal surface with entropy analysis. This study presents a novel idea regarding the implementation of Tiwari and Das model on Casson fluid model by considering ethylene glycol as a base fluid. Tiwari and Das model considers nanoparticles volume fraction for heat transfer enhancement instead of the Buongiorno model which heavily relies on thermophoresis and Brownian diffusion effects for heat transfer analysis. The velocity slip and convective slip boundary conditions have been employed at the surface of the sheet. By utilizing the suitable transformations, the modeled PDEs (partial-differential equations) are renewed in ODEs (ordinary-differential equations) and treated these equations numerically with the help of classical Keller box method. Two different classes of nanofluids, Copper-Ethylene Glycol () and Molybdenum Disulfide-Ethylene Glycol () have been taken into considering for our analysis. The behaviour of surface drag coefficient and Nusselt number for the varied values of various sundry parameters is designed via tables. Our findings show that an increase in the Reynolds and Brinkman numbers increased the overall entropy of the system.
