Abstract
A new approach is proposed for analyzing the compressible turbulent boundary layvr with arbitrary pressure gradient. Utilizing a compressible law-of-the-wall and n Crocco energy approximation, the new theory integrates the momentum equation across the boundary layer in terms of inner variables only. The result is a single first-order ordinary differential equation for skin friction, devoid of integral thicknesses and shape factors. When analyzed for flat plate flow, this new equation has an exarl solution apparently superior in accuracy to any other flat plate theory (Table 1). A new equation also agrees well with supersonic skin friction data in both favorable and adverse pressure gradients. The new theory contains an explicit separation criterio”. and is the simplest and possibly most accurate existing analysis for compressible turbulent flow. © 1972 by ASME.
