Abstract

In this paper we discuss the effect of dissipation and thermo diffusion on convective heat and mass transfer flow of a viscous fluid, in a non uniformly heated vertical channel bounded by flat walls. A non-uniform temperature is imposed on the walls and the concentration on these walls is taken to be constant. The viscous dissipation is taken in to account in the energy equation assuming the slope of the boundary temperature to be small. We solve the governing momentum, energy and diffusion equations by a perturbation technique. The velocity, the temperature, the concentration, the rate of heat transfer and Shear wood Number have been analyzed for different variations of the governing parameters. The dissipative ef ects on the flow, heat and mass transfer are clearly brought out.

Keywords: Dissipation, Thermo diffusion, Heat and Mass Transfer.
