Burley, Jr, W M

Van Driest' s turbulent boundary layer theories are useful for determining heat transfer coefficients and skin temperatures for bodies moving at supersonic speeds. Since Van Driest's results are in a form difficult to evaluate, an explicit equation for skin-friction coefficient was developed by curve-fitting which gives good accuracy for the ranges of Mach numbers from 1.0 to 8.0, temperature ratios from 1.0 to 6.0, and Reynolds' numbers from 1 x 10/sup 6/ to 100 x 10/sup 6/.
