Abstract
In this article, mixed convective flow of nanofluids in a vertical porous channel along with heat generation or absorption is examined. The governing equations incorporates the Brownian motion and thermophoresis effects. The dimensionless governing equations are coupled and non-linear. These equations are solved by using Adomian decomposition method and bvp4c MATLAB code. The velocity, temperature and concentration fields for variation of various physical parameters are
analysed graphically. The values of Nusselt number and Sherwood number at the walls of the channel are tabulated and analysed.
Keywords: Porous medium, nanofluids, heat source or sink, Brownian motion, thermophoresis, Adomian decomposition method
