Influence of chemically reacting species in MHD stagnation point flow of an Oldroyd-B fluid with partial slip

Abstract

This paper looks into the influence of chemically reacting species on the magnetohydrodynamics stagnation point flow and mass transfer of an electrically conducting Oldroyd-B fluid over a stretching sheet with partial slip at the surface. The slip boundary condition for a two-dimensional Oldroyd-B fluid is obtained for the first time. A similarity solution for the system of equations is obtained using finite difference method in which a coordinate transformation is employed to transform the semi-infinite physical space to a bounded computational domain. The quantities of interest like fluid velocity and concentration of species are shown graphically and discussed under the influence of emerging parameters. An excellent agreement of the present results with existing values in special cases is achieved.
