UNSTEADY MHD BOUNDARY LAYER FLOW WITH DIFFUSION AND FIRST-ORDER CHEMICAL REACTION OVER A PERMEABLE STRETCHING SHEET WITH SUCTION OR BLOWING

摘要: In this study, unsteady MHD boundary layer flow with diffusion of chemically reactive species undergoing first-order chemical reaction over a permeable stretching sheet suction or blowing and also power-law variation in wall concentration is investigated. Using similarity transformation, the governing partial differential equations are converted into nonlinear self-similar ordinary equations. The transformed then solved by finite difference method using quasi-linearization technique. Due to increase unsteadiness parameter, velocity initially decreases, but after certain point it increases. A similar effect observed case distribution. magnetic parameter causes decrease an concentration. For increasing strength applied both momentum thicknesses decrease. On other hand, has reverse effects. Moreover, mass tr...
