Sanjib Sengupta . Influences of Soret effect and Thermal Radiation on MHD Mixed Convective Mass Transfer Flow with Chemical Reaction and Heat Generation/Absorption. Communications on Applied Electronics. 1, 7 ( May 2015), 14-19. DOI=10.5120/cae-1587
Abstract
The present paper deals with two dimensional steady laminar flow of a Newtonian electrically conducting incompressible viscous fluid past a permeable plate immersed in Darcian porous media in presence of thermal diffusion (Soret), thermal radiation, first order chemical reaction and heat generation / absorption effects. The exact solutions for velocity, temperature and concentration fields as well as skin-friction, Nusselt number and Sherwood number are obtained and discussed through graphs and tables in presence of various pertinent parameters involve in the study. The main velocity is found to increase due to increase in parametric values of thermal diffusion, permeability parameter, while the increase in Schmidt number and chemical reaction parameter decrease the flow rate. It is also seen that, the mass transfer rate accelerates under the influence of Schmidt number and chemical reaction parameter, whereas the skin-friction increases as thermal diffusion parameter increases and decreases due to increase in chemical reaction parameter.
