Abstract

In the present paper, the effect of homogeneous-heterogeneous reactions on MHD Casson fluid over a stretchable rotating disk with variable thickness is examined. Slip effects are taken into account. The governing coupled nonlinear partial differential equations are reduced into a system of coupled nonlinear ordinary differential equations by using Von Karman similarity transformation. Further, solutions are obtained via efficient semi-analytical method Optimal Homotopy Analysis Method (OHAM). The results are presented graphically in order to see the influence of pertinent parameters on the velocity and concentration fields. Homogeneous reaction parameter and heterogeneous reaction parameter have a converse impact on fluid concentration.
