Transportation of activation energy in the development of a binary chemical reaction to investigate the behavior of an Oldroyd-B fluid with a nanomaterial

Abstract

The magnetohydrodynamic flow of an Oldroyd-B nanomaterial over a stretching surface is considered. An energy equation is constructed subject to Joule heating and radiative heat flux. Mechanisms of Brownian movement and thermophoresis force are also taken into account. A chemical reaction at the surface associated with Arrhenius energy is implemented. Thermal and solutal effects are addressed at the boundary. Appropriate transformations are adopted for the alteration of potential difference equations into ordinary ones. The ordinary equations are solved for the series via the homotopy analysis method. Velocity, concentration, temperature, Nusselt number, mass concentration and Sherwood number are discussed graphically, through different flow parameters. The main conclusions are listed.
