EXPERIMENTAL REYNOLDS ANALOGY FACTOR FOR A COMPRESSIBLE TURBULENT BOUNDARY LAYER WITH A PRESSURE GRADIENT.

Abstract

An experimental study was made of the effect of a favorable pressure gradient on the Reynolds analogy factor, K = 2St/C sub f, for a natural two-dimensional supersonic turbulent boundary layer in air. Integrated values of the skin friction coefficient and Stanton number were determined from experimental data. The results show that Colburn's value of K = Pr to the - 2/3 power, which was found empirically from zero pressure gradient data, is satisfactory for relating skin friction and heat transfer for the magnitudes of pressure gradients investigated.
