Thermal analysis of AIN-Al2O3 Casson hybrid nano fluid flow through porous media with inclusion of slip impact

Abstract

A mathematical analysis of magnetized Casson hybrid nanofluid flow over a stretching permeable sheet with porosity effects and being exposed to thermal convective boundary conditions with slip in velocity and concentration have been presented numerically. The attained steady-state partial differential equations are highly coupled and nonlinear in nature and are not agreeable to any of the direct techniques. Hence, they are being reduced to coupled-nonlinear ordinary differential equations by means of appropriate similarity transformations. A MATLAB-based, bvp4c scheme has been employed to obtain numerical solutions. Suitable graphs have been plotted which demonstrates the fluid flow velocity, temperature, concentration and micro-organism distribution fields in the boundary layer regime. Magnifying Casson fluid parameter and porosity leads to a decline in the velocity field. Amplifying the concentration slip decays the concentration profile. A comparative analysis was conducted to confirm the findings from previous research, demonstrating strong consistency with the results previously documented. Enhancing heat transfer in microelectromechanical systems (MEMS), optimizing medical drug delivery techniques, and boosting the efficiency of cooling systems in industrial processes are all potential applications of this study.
