S. S. Das, S. Panda, N. C. Bera

This paper concerns with the effect of radiative heat transfer on unsteady hydromagnetic free convective couette flow of a viscous incompressible electrically conducting fluid in presence of variable suction. Employing perturbation technique, the governing equations of the flow field are solved and the expressions for the velocity, temperature, skin friction and the heat flux i.e. the rate of heat transfer in terms of Nusselts number Nu are obtained. The effects of the important flow parameters such as radiation parameter F, magnetic parameter M, slip flow parameters h1, h2; suction parameters a1, a2 , Prandtl number Pr etc. on the velocity and temperature of the flow field are analyzed and discussed graphically with the help of figures and tables.
