Abstract

This article addresses non-linear mixed convection flow due to Riga plate with double stratification. Heat transfer analysis is reported for heat generation/absorption and non-linear thermal radiation. Physical problem is mathematically modeled and non-linear system of partial differential equations (PDEs) is achieved. Transformations are then utilized to obtain non-linear system of ordinary differential equations. Graphical descriptions for velocity, temperature and concentration distributions are captured and argued for several set of physical variables. Features of skin friction and Nusselt and Sherwood numbers are also illustrated. Our computed results indicates that the attributes of buoyancy ratio and modified Hartman number enhance the velocity distribution.
