Effects of MHD Visco-Elastic Fluid Flow Past a Moving Plate with Double Diffusive Convection in Presence of Heat Generation
Authors: ,
Abstract: During the course of present investigation, effects of first order homogeneous chemical reaction and thermal radiation on two dimensional MHD flow of a visco-elastic fluid past a moving porous plate by considering double diffusive convection in presence of heat generation has been analyzed. A uniform magnetic field is applied in the direction normal to the moving plate. Also, the plate is considered to be moving with a constant velocity along the flow field. The present theoretical study has been carried out under perturbation approximation. Also, the expressions for velocity, temperature, concentration, shearing stress, rate of heat transfer and rate of mass transfer have been obtained. The velocity profiles and shearing stress for both heated and cooled plate are depicted for various values of flow parameters to observe the visco-elastic effects. The rate of heat transfer i.e. Nusselt number and the rate of mass transfer i.e. Sherwood number are not significantly affected by the visco-elastic parameter.
