Buoyancy force and thermal radiation effects in MHD boundary layer visco-elastic fluid flow over continuously moving stretching surface

An analysis is performed to study the effect of the Buoyancy force and thermal radiation in MHD boundary layer visco-elastic fluid flow over continuously moving stretching surface embedded in a porous medium. The following cases of surface conditions are studied namely: (i) a surface with prescribed wall temperature and (ii) a surface with prescribed heat flux. Numerical calculations have been carried out for various values of non-dimensional physical parameters, and tabulated results for Skin friction coefficient and Nusselt number, are presented and discussed.
