SUMMARY OF STUDIES ON THE MEASUREMENT OF LOCAL SKIN FRICTION BY MEANS OF THE SURFACE IMPACT OR PRESTON TUBE,

Abstract

This report summarizes work done on the use of the surface impact probe, or Preston tube, method of measuring skin friction in turbulent, compressible boundary layers. The theory for incompressible flow was extended to the case of adiabatic, compressible flow, and the extended theory was experimentally shown to be valid. It has also been demonstrated that the extension is applicable to adiabatic flow with moderate adverse pressure gradients. Experimental and theoretical efforts to apply the impact probe method to compressible flows with moderate, aerodynamic heating were only partially successful. (Author)
