Abstract

The present analysis investigates non-orthogonal stagnation point flow and heat transfer of a dual stratified Casson fluid in the presence of radiation. A set of partial differential equations of the physical model is transformed into a system of coupled non-linear ordinary differential equations as a first step (or initially) and then are solved numerically. Effects of the physical parameters on velocity and temperature fields, and species concentration are presented through graphs. The coefficient of surface drag, local heat and mass fluxes are also presented and discussed. Authenticity of the present study is ensured by comparing our results with the available results in the literature and is found to be in a very good agreement. Undershoot of temperature (concentration) is noticed due to excessive thermal (solutal) stratification. For higher Prandtl (Schmidt's) numbers this undershoot is more significant. Stream contours are plotted for several sets of values of the stagnation point flow parameter B. Stream contours are seen to skew to the right of the stagnation point for B<0 and to the left when B>0.
