Abstract

The present study is a part of a high-Reynolds-number experiment designed to establish a reliable data base helping to improve RANS turbulence models. In this work skin friction measurements were conducted in turbulent flows with significant pressure gradient using oil-film interferometry. The experiments were performed on a large-scale test model for three different flow velocities of 10, 23 and 36 m/s. Analysis of the skin friction distributions indicates that the state of the turbulent boundary layer remained out of equilibrium along the whole area investigated.
