A Micropolar Fluid's Mhd Mixed Convective Heat Transfer Across An Unsteady Stretching Porous Wedge Joule Heating And Viscous Dissipation

Abstract

The effects of viscous dissipation and Joule heating with convective boundary condition are taken into consideration in this study as it numerically examines the heat and mass transfer properties of a two-dimensional unsteady MHD mixed convective flow of a micropolar fluid along a stretching/stretching permeable wedge. The governing partial differential equations are first converted into non-linear ordinary differential equations using a set of similarity transformations. Then, the Nachtsheim-Swigert shooting iteration technique and a sixth order Runge-Kutta integration scheme are used to solve the equations numerically. Using graphs, the effects of non-dimensional governing parameters on temperature, velocity, and microrotation profiles are examined from a physical perspective. For the various values of the relevant parameters, the rate of heat transfer, plate couple stress, and local skin friction coefficient are also examined.
