Effect of Richardson number on double-diffusive mixed convective slip flow,Heat and Mass transfer of MHD Casson fluid

An analysis of the heat and mass transfer in a mixed-convective double diffusive flow with convective boundary conditions is carried out in this paper. The governing equations are solved numerically by using Runge-Kutta method with shooting procedure with Matlab software. An accuracy of the numerical procedure has been validated through a results of the current work when compared with prior available results in the literature. The values of shear surface stress, Nusselt and Sherwood number are increasing with increasing values of Prandtl number. The effect of Biot number B i > 0.1 on flow and heat transfer are also investigated and further it is observed that friction coefficient, Nusselt number and Sherwood number are increasing due to enhancing values of Biot number. In the present paper it is noticed that the increasing in estimations of Casson parameter slowdown the heat transfer rate and accelerates mass transfer rate. The results are in good agreement with existing findings The impact of pertinent constraints on distinct flow parameters are determined and analysed through tables and graphs.
