Radiation Effects on Unsteady MHD Flow of A Visco-Elastic Fluid Along Vertical Porous Surface With Heat Source and Chemical Reaction

Pavan , G. S. S. Raju

An unsteady two dimensional magnetohydrodynamic flow of a visco-elastic incompressible fluid (Walters B₀ fluid model) along an infinite hot vertical porous surface bounded by porous medium with free stream as well as suction velocity in the presence of Thermal radiation, heat surface and chemical reaction has been investigated. The governing equations of motion, energy and concentration are solved by the successive perturbation technique. The variations in the fluid velocity, temperature and concentration are shown graphically where as numerical values of skin-friction; Nusselt number and Sherwood number are presented in tabular form.
