EFFECT OF TEMPERATURE-DEPENDENT VISCOSITY ON MHD MIXED CONVECTIVE FLOW FROM AN EXPONENTIALLY STRETCHING SURFACE IN POROUS MEDIA WITH CROSS-DIFFUSION
要約
A numerical model is developed to investigate the effects of variable viscosity, and Soret and Dufour numbers on MHD mixed convective flow, heat and mass transfer from an exponentially stretching vertical surface embedded in a porous medium. Stretching velocity, wall temperature, and wall concentration are assumed to have specific exponential function forms. The governing partial differential equations are transferred into a system of ordinary differential equations, which are solved numerically using a linearization method. The accuracy and rate of convergence of the solution has been tested and compared with the Matlab bvp4c solver and earlier study. The effects of selected fluid and material parameters on the velocity, temperature, and concentration profiles are determined and discussed. The skin-friction, and heat and mass transfer coefficients have been obtained and analyzed for various physical parametric values.
