A COMPARISON OF FOUR SIMPLE CALCULATION METHODS FOR THE COMPRESSIBLE TURBULENT BOUNDARY LAYER ON A FLAT PLATE

Abstract

Four simple calculation procedures for estimating the heat transfer and skin friction for a turbulent compressible boundary layer on a smooth flat plate are compared with experimental data in flows approximating the boundary layer edge conditions on the bottom surface of the Space Transportation System orbital vehicle. The methods compared are Eckert's reference enthalpy, the adiabatic wall reference enthalpy, Spalding and Chi, and the reference density- viscosity-method. For the data used in the comparison the most consistently accurate prediction of the skin friction is given by Spalding and Chi's method. This method also gives the best estimates of the heat transfer when used with Von Karman's equation for the Reynolds analogy factor.
