“…The filtration and mass transfer process, ultrafiltration in the Bowman capsule, fluid reabsorption through renal proximal tubule present in kidney, blood filtration process in artificial kidneys, cooling transpiration, biological fluids, polymeric liquids, and filtration process due to reverse osmosis are examples of such flows. [1][2][3][4][5][6][7][8][9][10][11] It is analyzed through the literature that scientists have tried to solve the hydrodynamic problems in permeable tubes and channels [12][13][14][15] with different reabsorption fluid velocities on the boundary. Marshall et al 16 examined the viscous flow in a uniform channel with permeable boundaries and presumed that the leakage of the fluid is proportional to the pressure change along the channel wall.…”

This research presents the analytical study of the creeping flow of a Maxwell fluid in a permeable slit under the effect of linear reabsorption. Analysis of fluid leakage on the slit wall is carried out with the help of the law of conservation of momentum in the rectangular coordinates. The mathematical model in the form of the system of nonlinear partial differential equations is solved by the recursive approach explaining the hydrodynamic aspects of creeping Maxwell fluid flow. The expressions for the velocity field, hydrostatic pressure, stream function, leakage flux, and fractional reabsorption on the boundary of the slit are obtained from the mathematical model. Graphical analysis is also established to demonstrate the effects of emerging parameters due to linear reabsorption on slit boundary and relaxation time. It is analyzed that the horizontal and vertical velocity decelerates by the growing values of the relaxation parameter, but the reabsorption rate gives an increasing effect on the shear stress, volume flow rate, and vertical velocity. This analytical study will help the bioengineers in designing the medical tools with the required pressure and flow rate, therefore the application of this model for the hemodialyzer is also important.

“…Nowadays, many researchers have attempted to develop heat transfer properties and boundary layers beyond several types of fluids with various physical conditions, for example, Waini et al (2021a, 2021b) and Zidan et al (2021). As this study focusses on the thermal radiation effect, some available reviews focussed on this effect can be assessed through Waini et al (2019a), Yashkun et al (2021) and Zainal et al (2020).…”

Purpose The investigation of fluid flow and heat transfer is incredibly significant in the present era, particularly in the engineering and manufacturing industries. Hence, this study aims to concern with analysing the unsteady stagnation point flow towards a permeable stretching/shrinking Riga plate of Al2O3-Cu/H2O. The effect of thermal radiation on the boundary layer flow is also taken into account. Design/methodology/approach The multi-variable differential equations with partial derivatives are transformed into third-order and second-order differential equations by applying appropriate transformations. The reduced mathematical model is solved in the MATLAB system by using the bvp4c procedure. This solution approach is capable of producing multiple solutions once the necessary assumptions are provided. Findings The results of various control parameters were analysed, and it has been observed that raising the solution viscosity from 0% to 0.5% and 1% improves the coefficient of skin friction and thermal conductivity by almost 1.0% and 1.9%. Similar response and observation can be witnessed in the addition of modified Hartmann number where the highest values dominate about 10.7% improvement. There is a substantial enhancement in the heat transfer rate, approximately 1.8% when the unsteadiness parameter leads around 30% in the boundary layer flow. In contrast, the increment in thermal radiation promotes heat transfer deterioration. Further, more than one solution is proven, which invariably leads to a stability analysis, which validates the first solution’s feasibility. Originality/value The present results are new and original for the study of flow and heat transfer on unsteady stagnation point flow past a permeable stretching/shrinking Riga plate in Al2O3-Cu/H2O hybrid nanofluid with thermal radiation.

“…[18][19][20] Further analysis of heat transfer has been performed by various researchers by using nanofluids. [21][22][23][24] Not just the physical properties of nanoparticles affect the heat transfer performance of a fluid, the physical appearance of nanoparticles also contributes to both flow characteristics and heat transfer performance of a fluid containing nanoparticles. This was experimentally demonstrated by Timofeeva et al 25 and Xie et al 26 for fluids containing Al 2 O 3 nanoparticles of various shapes.…”

The analogy of nanoparticle shapes on the theory of convective heat transfer of Au–Fe₃O₄ Casson hybrid nanofluid

In recent times, Au nanoparticles have been commonly used for delivering the drug especially in the case of hypothermia of tumors, but low absorption of IR light does not solve destruction of tumor cells. However, nanoparticles such as Fe3O4 coated with Au could be used to deliver the drug to a specific spot due to applied external magnetic field. Due to these applications, boundary layer approximation is invoked to simplify the mathematical model. This paper presents the nanoparticle shape analysis and heat transfer features of the Au–Fe3O4–blood hybrid nanofluid flowing past a stretching surface on a magnetohydrodynamic medium. Numerical solutions of nonlinear differential equations are obtained by RKF‐45 method with the help of shooting technique. The behavior of emerging parameters is described graphically for velocity and temperature profiles. It is found that the blade‐shaped Au and Fe3O4 nanoparticles have better thermal conductance than brick, sphere, cylinder, needle, and platelet shapes. It is also observed that the Lorentz force generated due to magnetic field helps in controlling the flow and enhance the thermal conductivity of hybrid nanofluid.
