Group solution of unsteady free-convection flow from a continuous moving vertical surface subjected to constant beat flux

The problem of heat and mass transfer in an unsteady free convection flow over a continuous moving vertical sheet in an ambient fluid is investigated for constant heat flux. The nonlinear coupled partial differential equation governing the flow and the boundary conditions are transformed to a system of ordinary differential equations with appropriate boundary conditions. The obtained ordinary differential equations are solved numerically using the shooting method. The effect of Prandtl number and viscosity of the fluid on the thermal boundary-layer and velocity boundary-layer is investigated and plotted in curves. (c) 2004 WILEY-VCH Verlag GmbH \& Co.
