Numerical Solution of Micropolar Fluid Flow with Zero Mass Flux of Nanoparticles at Stretching Surface with a Porous Medium

This paper investigates the comprehensive investigation of mixed convection flow and heat transfers analysis of Micropolar by considering porous medium and heat absorption. Subsequently, mathematical formulation was modeled using boundary conditions. Two major aspects, Brownian motion and thermophoresis are addressed in the energy and concentration equation which are coupled with momentum equation. By using similarity variables, the entire system of partial differential equations govern through momentum, energy, angular momentum and concentration are converted into system of nonlinear ordinary differential equations. Nonlinear systems are solved by using numerical approach with bvp4c function in MATLAB that is based on the collocation method, specifically the three-point Lobatto IIIa formula is directed to type of finite difference method. Results are obtained for various emerging parameters. It has been observed that skin friction decreases for increasing values of Hartmann number and Eckert number. Decreasing trend of bar graphs is observed against Nusselt number and Sherwood number against Brownian motion and thermophoresis parameters.
