Convective heat transfer in a laminar boundary layer near the separation point
Abstract
Presented in this paper is a new formula for determining temperature profile and the rate of heat transfer near a separation point in a laminar boundarylayer flow over a two dimensional or axisymmetric body having a step change in surface temperature. A special coordinate transformation and the Merktype series expansion technique for the temperature are employed to transform the energy equation into a set of secondorder ordinary differential equations. These differential equations are expressed in terms of universal functions, and the closed form solutions to the universal functions are obtained. The closed form solutions, in conjunction with the coefficients in the series expansion, form a general formula which represents a complete temperature field in the boundary layer near the separation point. The general formula is applied to the special cases of wedge flows and Howarth's retarded flows to examine the rate of heat transfer near or at the separation point.
