Two-dimensional Unsteady Boundary Layer Flow with Mixed Convection Along a Semi-Infinite Symmetric Wedge

Abstract

The mixed convection of a two-dimensional, unsteady boundary-layer flow of a viscous incompressible fluid past a symmetric wedge has
been studied. The resulting system of non-linear ordinary coupled differential equations has been solved analytically for small time and
numerically by three individual competent methodologies; namely (a) Series solutions method for small time, (b) Asymptotic solutions for
large time and (c) Implicit finite difference method (FDM) together with the Keller-box elimination scheme. Numerical results obtained for
skin-friction coefficient, heat transfer rate, streamlines and isotherms with the effect of dissimilar leading parameters such as different
time , the exponent m, mixed convection parameter  and Prandtl number Pr.
