Abstract

This paper, analysed by computation, the behaviour of thermal radiation and heat generation/absorption in a viscous Magnetohydrodynamics Micropolar fluid through a porous medium of a stretching sheet with suction/injection. The investigation is done using the set of coupled nonlinear partial differential equations that describe the dynamics of the flow and heat transfer. These equations are transformed into a system of ordinary differential equations which are solved via the Galerkin Weighted Residual method. The behaviour of various embedded parameters adopted was presented graphically and discussed through tables accordingly. Aside from other major findings, the novel result shows that microrotation is a decreasing function of Magnetic and porosity parameters while increasing values of heat generation magnify the fluid molecules and strengthen the thermal effect on fluid at a far field. Also, higher variation of coupling constant depicts a lower viscosity nature and reduces the rotation of the fluid molecules. The validation obtained agreed with the literature.
