MHD effects on heat transfer over stretching sheet embedded in porous medium with variable viscosity

(in lingua inglese)

The present study gives the numerical solution for MHD effects on the boundary layer flow and heat transfer with a variable fluid viscosity on flow past a heated stretching sheet embedded in porous medium in presence of heat source/sink and viscous dissipation. Efficient method of Lie group analysis is used to solve the governing equations of motion. This procedure helps in removing the difficulties faced in solving the equations arising from the non-linear character of the partial differential equations. The scaling symmetry group is very essential procedure to comprehend the mathematical model and to find the similarity solutions for such type of flow which have wider applications in the engineering disciplines related to fluid mechanics.
