نویسندگان
چکیده
The objective of this paper is to analyze the effect of radiative heat and mass transfer on unsteady natural convection couette flow of a viscous incompressible fluid in the slip flow regime in presence of variable suction and radiative heat source. The governing equations of the flow field are solved employing perturbation technique and the expressions for the velocity, temperature, concentration distribution, skin friction and the rate of heat transfer i.e. the heat flux in terms of Nusselts number Nu are obtained. The effects of the pertinent parameters such as suction parameters 1, 2 ; Grashof number for heat and mass transfer Gr, Gc; slip flow parameters h1, h2; radiation parameter F, permeability parameter Kp, Schmidt number Sc, Prandtl number Pr, etc. on the flow field have been studied and the results are presented graphically and discussed quantitatively.
