FREE CONVECTIVE HEAT AND MASS TRANSFER FLOW PAST AN OSCILLATING PLATE WITH HEAT GENERATION, THERMAL RADIATION AND THERMO-DIFFUSION EFFECTS
Sanjib Sengupta and Mausumi Sen

Abstract: An exact analysis of the physical effects of thermo-diffusion (Soret) and thermal radiation on free convective unsteady two-dimensional heat and mass transfer flow of a thermally generating Newtonian viscous incompressible fluid on an oscillating vertical permeable surface is presented. The governing system of partial differential equations is transformed into a set of ordinary differential equations by using a set of periodic transformations. Cogly-Vincentine-Gilles equilibrium heat flux model is incorporated in the energy equation. Exact closed form of solutions for velocity, temperature and concentration fields as well as skin-friction, Nusselt and Sherwood numbers are obtained in terms of various pertinent parameters present and are finally interpreted numerically through graphs and tables. |
Keywords and phrases: free convection, mass transfer, heat generation, thermal radiation, thermo diffusion. |
