UNSTEADY FREE CONVECTION BOUNDARY-LAYER FLOW PAST AN IMPULSIVELY STARTED VERTICAL SURFACE WITH NEWTONIAN HEATING

R. C. Chaudhary, Preeti Jain

Open publisher page 44 citations

Abstract

An exact solution of the unsteady free convection boundary-layer flow of an incompressible fluid past an infinite vertical plate with the flow generated by Newtonian heating and impulsive motion of the plate is presented here. The resulting governing equations are non-dimensional zed and their solutions were obtained in closed form with the help of Laplace-transform technique. A parametric study of all involved parameters is conducted and a representative set of numerical results for the velocity, temperature and skin-friction is illustrated graphically and physical aspects of the problem are discussed.
