Melting heat transfer with radiative effects and homogeneous–heterogeneous reaction in thermally stratified stagnation flow embedded in porous medium

Abstract

The present article deals with thermally stratified stagnation-point flow saturated in porous medium on surface of variable thickness along with more convincing and reliable surface condition termed as melting heat transfer. Homogeneous–heterogeneous reaction and radiative effects have been further taken into account to reconnoiterproperties of heat transfer. Melting heat transfer and phenomenon of homogeneous–heterogeneous reaction have engrossed widespread utilization in purification of metals, welding process, electroslag melting, biochemical systems, catalysis and several industrial developments. Suitable transformations are utilized to attain a scheme of ordinary differential equations possessing exceedingly nonlinear nature. Homotopic process is employed to develop convergent solutions of the resulting problem. Discussion regarding velocity, thermal field and concentration distribution for several involved parameters is pivotal part. Graphical behaviors of skin friction coefficient and Nusselt number are also portrayed. Concentration of the reactants is found to depreciate as a result of strength of both heterogeneous and homogeneous reaction parameters. With existence of melting phenomenon, declining attitude of fluid temperature is observed for higher radiation parameter.
