UNSTEADY MHD FREE-CONVECTION FLOW IN THE PRESENCE OF INCLINED MAGNETIC-FIELD WITH SUCTION AND HEAT-SOURCE

An analytical study is performed to examine the effects of a magnetic field on free convection flow when: (i) plate is moving impulsively wi th uniform velocity U; (ii) suction velocity normal to the plate is co nstant; (iii) fluid is subjected to a constant heat source of absorpti on type; (iv) magnetic lines of forces are assumed to be fixed relativ e to the porous plate; (v) magnetic field makes an angle or normal to the porous plate. The expressions for the velocity field and skin fric tion are obtained by the Laplace transform technique. The influences o f the various parameters on flow field and skin friction are extensive ly discussed.
