Homogeneous–heterogeneous reactions in stagnation point flow of Casson fluid due to a stretching/shrinking sheet with uniform suction and slip effects
This study deals with the effects of homogeneous–heterogeneous reaction on boundary layer flow of a non-Newtonian fluid near a stagnation point over a porous stretching/shrinking sheet with a constant suction. In this analysis Casson fluid is used to indicate the non-Newtonian fluid behavior by taki...

| description | This study deals with the effects of homogeneous–heterogeneous reaction on boundary layer flow of a non-Newtonian fluid near a stagnation point over a porous stretching/shrinking sheet with a constant suction. In this analysis Casson fluid is used to indicate the non-Newtonian fluid behavior by taking diffusion coefficients of both reactant and autocatalysis equal. The basic flow equations in form of partial differential equations are converted into a system of ordinary differential equations and then solved numerically. The influences of physical and fluid parameters on the velocity and concentration profiles are analyzed, presented and discussed through graphs. An increase in fluid velocity slip parameter reduces the magnitude of the velocity as well as increases the concentration in the boundary layer region. Furthermore, a unique solution is possible for all values of the stretching parameter (λ > 0), while in case of shrinking parameter (λ < 0), solutions are possible only for its limited ranges. |
