Abstract
Turbulence measurements were obtained in a three-dimensional supersoni c turbulent boundary layer. A 20 degrees curved fin was used to genera te a three-dimensional compression of a boundary layer at Mach 3 in th e absence of shock waves. Data include hot-wire measurements of five c omponents of the Reynolds stress tensor. The results are interpreted i n terms of the mean flow field history of the turbulence. It is demons trated that in-plane curvature can have a strong stabilizing effect on the turbulence.
