Calculations of turbulent shear stress distributions are reported for zero pressure gradient and adverse pressure gradient supersonic turbulent boundary layer flow. The calculations are accomplished by numerically integrating the equation for conservation of streamwise momentum using mean profile experimental data. The mixing length distributions were also determined and indicate that the mixing length distribution is significantly altered for the adverse pressure gradient flow. Finite difference boundary layer computations using an altered mixing length distribution show improved agreement with experimental measurements of skin friction for the adverse pressure gradient flow.
