Abstract

The Analysis of Influence of second order resistance and variation in fluid properties on double diffusive mixed convection is studied numerically. In the study of boundary layer flow with porous medium for the physical system here, the extended darcy model is considered. The mathematical formulation leads to equations which are highly coupled and non-linear in nature. Using similarity transformations, they are converted to first order ODE and solved approximately applying shooting technique. Fluid flows for double diffusive mixed convection are discussed by plotting the graphs for transport processes. It is observed that the effect of second order resistance are more prominent for heat and mass transfer when compared with its absence of the study made. A good agreement is found when interpretation of the effects of various significant parameters are analysed and compared.

Keywords
