The unsteady MHD flow under the action of chemical reaction and thermal radiation at the stagnation point of a rotating sphere

Abstract

In the present work, we have studied the unsteady MHD flow under the action of thermal radiation and chemical reaction at the stagnation point of a rotating sphere. By using similarity transformation, the unsteady non-linear boundary layer equation obtained as a result of heat transfer and mass transfer along with momentum were changed to a set of ordinary differential equations. Through the use of MATLAB’s built in solver bvp4c, the obtained differential equations were solved. Fluid velocity profile along with temperature profile and species concentration profiles are drawn for radiation parameter (R a) and chemical reaction parameter (K and the obtained results are discussed. r).
