Abstract : An approximate method of calculating the surface heat transfer in a transpired boundary layer is presented. The method is based on an idea for refining the momentum integral technique. A semi-infinite, isothermal flat plate with uniform surface mass flux is used to demonstrate the method. The flow is assumed to be laminar. Results are presented for both incompressible and compressible boundary layers, and comparisons are made with numerical solutions or other approximate results. The findings are indicative of the potential of the method for development into an efficient tool for studying boundary-layer flows of a more complex nature. (Author Modified Abstract)
