“…It is shown that the entropy generation Eg increases as Ec increases whereas it decreases as 𝛽 2 increases. Moreover, the obtained curves don't intersect at the boundary of channel; this is due to the boundary conditions given in (15), and they are coincide near the axis of channel, namely in the interval y∈ [0, 0.35]. 9) Fig( 10) Fig( 11) Fig( 12)…”

The present paper analyzes the influences of entropy generation as well as slip velocity and temperature conditions on MHD micropolar biviscosity nanofluid flow through a porous medium in a channel with peristalsis. The fluid effects of mixed convection, radiation, viscous dissipation and thermal micropolar properties are taken into consideration. The assumptions of low-Reynolds number and long-wavelength are used to simplify the governing equations of this problem. A semi-analytical solutions of these equations are obtained by using homotopy perturbation method. Moreover, the entropy generation is obtained in this study. Results are discussed for various parameters of the problem and depicted graphically. Physically, our model is consistent with the motion of digestive juice in the bowel whenever we are going to insert an endoscopy through it.

Convective Heat Transfer Analysis for Aluminum Oxide (Al2O3)- and Ferro (Fe3O4)-Based Nano-Fluid over a Curved Stretching Sheet

In this work, the combined effects of velocity slip and convective heat boundary conditions on a hybrid nano-fluid over a nonlinear curved stretching surface were considered. Two kinds of fluids, namely, hybrid nano-fluid and aluminum oxide (Al2O3)- and iron oxide (Fe3O4)-based nano-fluid, were also taken into account. We transformed the governing model into a nonlinear system of ordinary differential equations (ODEs). For this we used the similarity transformation method. The solution of the transformed ODE system was computed via a higher-order numerical approximation scheme known as the shooting method with the Runge–Kutta method of order four (RK-4). It is noticed that the fluid velocity was reduced for the magnetic parameter, curvature parameter, and slip parameters, while the temperature declined with higher values of the magnetic parameter, Prandtl number, and convective heat transfer. Furthermore, the physical quantities of engineering interest, i.e., the behavior of the skin fraction and the Nusselt number, are presented. These behaviors are also illustrated graphically along with the numerical values in a comparison with previous work in numerical tabular form.

“…Hybrid nanofluids are used in heat pipes, heat exchangers, cooling electronics, the auto industry, cooling nuclear systems, and biomedical applications. [6][7][8] Fluids with non-Newtonian properties have been used in a variety of technical applications, including hydraulic fracking and rehabilitation, as well as a wide range of industrial applications. In contrast, the equations of motion for non-Newtonian fluids are highly nonlinear.…”

The intention of this article is to explore the entropy generation of the Carreau hybrid nanofluid in a permeable rotating disk in the presence of thermal radiation, heat generation, and viscous dissipation. By applying the self-similarity variables, the partial differential equations are converted into ordinary differential equations and then the homotopy perturbation method is performed. Graphene oxide (Go) and Silver (Ag) are nanoparticles and kerosene oil as a base fluid is considered. Compared to the numerical technique (Runge-Kutta method), the homotopy perturbation method generates more precise and dependable results. The influence of sundry parameters is exhibited graphically for velocity, temperature, entropy generation, Bejan number, skin friction coefficient, and Nusselt number. The higher values of the Weissenberg number enhance the velocity profile and the opposite nature is observed in the porosity parameter. The entropy generation increases for larger values of the thermal radiation and electric field parameters. Carreau nanofluid expands under higher stress on the surface of the wall than Newtonian fluid. This type of problem would be used for electric devices and solar thermal systems. Moreover, the selected nanoparticles Graphene oxide and Silver play an important role in the biofunctionalization of protein, antibacterial, and anticancer therapy.
