Heat Radiation Affects Hydro Magnetic Flow in A Spinning Porous Disc Within a Heat-Producing and Absorbing Medium

Abstract

This study examines the impact of thermal radiation on the electrically conducting grey fluid's continuous laminar convective hydromagnetic flow over a rotating porous disk in a porous medium, using an external uniform magnetic field and heat generation/absorption. When the disc is placed in a perpendicular magnetic field, a uniform suction should be expected over its surface. A solution to a nonlinear ordinary differential equation can be obtained by applying the suitable similarity transformation suggested by von Karman to the controlling nonlinear partial differential equations. Everything related to heat transfer is covered here, including situations with prescribed surface temperature (PST) and prescribed heat flux (PHF). The numerical solutions are visually shown by graphs. These solutions are obtained by a fourth-order Runge-Kutta based shooting method. Fluid temperature and velocity, as well as the Prandtl number, heat produced or absorbed, medium porosity, suction parameter, and radiation parameter are all investigated in detail in this area. These impacts are illustrated via graphs. Results for different parameters are included in tables along with the corresponding Nusselt number and skin-friction coefficients. Consistent with the sources mentioned before, all of the results are in agreement.
