Abstract

Tani's integral method is extended to treat laminar two-dimensional compressible boundary layers with heat transfer and arbitrary pressure gradient for both attached and separated flows. A carefully chosen one-parameter family for the velocity profiles and a "universal" stagnation enthalpy profile are assumed for attached flows. The accuracy of the method is examined by comparing the results with several "exact" numerical solutions and satisfactory agreement is obtained. For separated flows one-parameter families are assumed for both the velocity and stagnation enthalpy profiles. In this case the accuracy of the method is poor; however, suggestions are made as to how it might be improved within the present framework.
