EFFECT OF VISCOUS DISSIPATION TERM IN ENERGY EQUATION ON MHD FREE CONVECTION FLOW PAST AN EXPONENTIALLY ACCELERATED VERTICAL PLATE WITH VARIABLE TEMPERATURE AND HEAT SOURCE

The theoretically examines an unsteady free convection flow of an incompressible viscous fluid past an exponentially accelerated vertical plate is analyzed by taking into an account the heat due to viscous dissipation under the influence of a uniform transverse magnetic field. The problem is governed by coupled nonlinear partial differential equations. Dimensionless equations of the problem have been solved by using perturbation technique. The effects of various parameter involving in the equations are discussed on velocity and temperature fields through graphs. Skin friction coefficient is derived, discussed numerically and presented in tabular form.
