the Arrhenius activation energy and binary chemical reaction are taken into account to consider the magnetohydrodynamic mixed convection second grade nanofluid flow through a porous medium in the presence of thermal radiation, heat absorption/generation, buoyancy effects and entropy generation. The items composing of the governing systems are degenerated to nonlinear ordinary differential equations by adopting the appropriate similarity transformations which are computed through Runge-Kutta-Fehlberg (RKF) numerical technique along with Shooting method. The solution is manifested through graphs which provides a detailed explanations of each profile in terms of involved parameters effects. The compared results maintain outstanding approach to the previous papers.

In this research article, the unsteady nanofluid flow between two horizontal plates is discussed. The main focus of this study is on the explanation of the relative study of water-based nanofluids with four different types of nanoparticles. The nanoparticles selected for this specific research article are copper oxide (CuO), aluminum oxide (Al 2 O 3 ), copper (Cu), and silver (Ag). The upper plate is moving downward with time-dependent velocity while the lower plate is stretching horizontally. Also the lower plate is made up of porous medium. The stream in permeable region is characterized by Darcy-Forchheimer relation. Cattaneo-Christov heat flux model is used for heat transfer phenomena. Viscous dissipation effect is taken in account. Skin friction and Nusselt number are numerically calculated. Total entropy generation is also discussed for squeezing system. Transformation technique is applied to transform the model from partial differential equations to ordinary differential equations. Homotopy techniques are applied to solve the problem. The influence of important parameters on velocity, temperature, and entropy profiles have been shown graphically and discussed in detail.

“…Furthermore, different studies on the flow and heat transfer behaviour as well as entropy generation for different non-Newtonian fluids under difference internal and external conditions. [55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70][71][72] The above reviewed studies have been the consequent of the various industrial and engineering applications of non-Newtonian fluids. Among the classes of non-Newtonian fluids, Carreau fluid which its rheological expressions were first introduced by Carreau, 73 is one of the non-Newtonian fluids that its model is substantial for gooey, high and low shear rates.…”

In this paper, combined influences of thermal radiation, inclined magnetic field and temperature-dependent internal heat generation on unsteady two-dimensional flow and heat transfer analysis of dissipative Casson-Carreau nanofluid over a stretching sheet embedded in a porous medium is investigated. Similarity transformations are used to reduce the developed systems of governing partial differential equations to nonlinear third and second orders ordinary differential equations which are solved using finite element method. In the study, kerosene is used as the base fluid which is embedded with the silver (Ag) and copper (Cu) nanoparticles. Also, effects of other pertinent parameters on the flow and heat transfer characteristics of the Casson-Carreau nanofluids are investigated and discussed. From the results, it is established temperature field and the thermal boundary layers of Ag-Kerosene nanofluid are highly effective when compared with the Cu-Kerosene nanofluid. Heat transfer rate is enhanced by increasing in power-law index and unsteadiness parameter. Skin friction coefficient and local Nusselt number can be reduced by magnetic field parameter and they can be enhanced by increasing the aligned angle. Friction factor is depreciated and the rate of heat transfer increases by increasing the Weissenberg number. A very good agreement is established between the results of the present study and the previous results. The results of present analysis can help in expanding the understanding of the thermo-fluidic behaviour of the Casson-Carreau nanofluid over a stretching sheet as applied in manufacturing industries and production engineering.
