Unsteady Free Convection near a Forward Stagnation Point at Small Prandtl Number
Abstract
Asymptotic solutions for small Prandtl number are obtained for unsteady free convection flow near the forward stagnation point of a two-dimensional symmetric body resulting from a step change in its surface temperature. It is shown that the boundary layer has the same singular character as that seen in the steady flow at small Prandtl number. The method of matched asymptotic expansions is used to obtain uniformly valid solutions.
