Numerical investigation of magnetohydrodynamic (MHD) radiative flow over a rotating cone in the presence of Soret and chemical reaction

Abstract

Present study is a numerical investigation of the flow, heat and mass transfer behaviour of magnetohydrodynamic flow over a vertical rotating cone through porous medium in the presence of thermal radiation, chemical reaction and Soret effects. Further, the numerical solutions are elucidated by using Runge-Kutta based shooting technique. Obtained results are validated with open literature and found an excellent agreement. The influence of non-dimensional governing parameters on velocity, temperature and concentration profiles along with the friction factor, local Nusselt and Sherwood numbers are determined and discussed with the help of graphs and tables. Results proved that the variable porosity parameter have tendency to enhance the heat and mass transfer rate. An increase in the buoyancy parameter depreciates the thermal and concentration boundary layer thicknesses. © 2018 National Laboratory for Aeronautics and Astronautics
