The influence of thermal radiation and stratification process on unsteady MHD flow over stretching sheet embedded in "nanofluid saturated porous medium with non-uniform heat source/sink was analyzed numerically in the present analysis. Proper similarity transformations reduce the nonlinear partial differential equations into ordinary differential equations and are solved numerically by using Galerkin Finite element method. Impact of different parameters, such as, magnetic parameter (0.1-1.0), buoyancy ratio parameter (0.1-4.5), radiation parameter (0.5-1.7), Rayleigh number (0.1-0.7), thermophoresis parameter (0.4-1.5), thermal stratification parameter (0.01-1.0), Brownian motion parameter (1.0-2.0), solutal stratification parameter (0.01-1.0), unsteadiness parameter (0.1-0.4), space-dependent (-0.5-0.4) and temperature dependent (-0.5-0.2) heat source/sink parameters on velocity, temperature and concentration profiles is calculated and are illustrated graphically. Skin-friction coefficient, Nusselt and Sherwood number are calculated and the results are shown in IP: 203.8.109.20 On: Tue, 16 Apr 2024 14:29:36 tabular form. It is found that the thermal stratification parameer deterorates the temperature of the fluid. The Copyright: American Scientific Publishers concentration of the fluid diminishes with rising values of solutal stratification parameter. The thermal boundary Delivered by Ingenta layer thickness elevates" with higher values of Brownian motion and thermophoresis parameters.
