Resumen de Diffusion of chemically reactive species in stagnation point flow of a micropolar viscoelastic fluid in a porous medium over a stretching/shrinking sheet
The transfer of chemically reactive species in stagnation point flow of a laminar micropolar viscoelastic fluid immersed in a porous medium over a stretching/shrinking surface is considered. The reactive species diffused into the fluid from the surface undergo a one stage isothermal and homogenous reaction. A similarity transformation is employed to transform the developed partial differential equations into a system of coupled ordinary differential equations. A convergent series solution is developed using homotopy analysis method in the whole spatial region (0 ≤ ƞ ≤ ∞). The obtained solutions for velocity, microrotation and concentration of species are analysed for various emerging parameters through graphs and tables.
