Effect of non-linear thermal radiation on the stagnation point flow of double diffusive free convection due to movingvertical plate

Purpose This paper aims to find the influence of convective heat transfer, buoyancy proportions, nonlinear thermal radiation, Prandtl number, Rayleigh number and Schmidt number on velocity, temperature and concentration profiles. Design/methodology/approach This paper explores the heat and mass transfer of a stagnation point stream of free convective Casson fluid over a moving vertical plate with nonlinear thermal radiation and convective boundary restrictions. The governing PDEs of stream, heat and concentration profiles were reformed into an arrangement of nonlinear ODEs by using similarity transformation. This framework was then tackled numerically by applying forth-order RK shooting strategy. Findings Distribution of flow, velocity and temperature profiles for different values of governing parameters are analyzed. Originality/value The original results are depicted in terms of plots.
