Abstract


Non-Newtonian MHD flow with heat and mass transfer in an electrically conducting fluid over an exponential stretching continuous porous sheet have been investigated in the present paper. Similarity analytical solution for highly non-linear momentum equation is obtained and the solution for heat and mass transfer analyses are obtained in terms of confluent hyper geometric functions. Accuracy of the analytical solution for the stream function is validated by drawing various graphs. These solutions involve an exponential dependent of stretching velocity, prescribed boundary temperature on the flow directionally coordinate. The effects of various physical parameters like visco-elastic parameter, Magnetic parameter, Prandtl number, Permeability parameter, Reynolds number, Nusslet number, Shrewood number and Eckert number on momentum, heat and mass transfer characteristics are discussed in detail
