### Abstract

The three-dimensional flow structure induced by normal shock-wave/boundary- layer interaction in a transonic diffuser is investigated experimentally and computationally. The experiments are done with the wall pressure measurement and oil-flow surface visualization. In the computational work, Reynolds-averaged Navier-Stokes equations are solved numerically with the κ-ω two-equation turbulence model. The solution reproduces very well the measured streamwise pressure distribution and the vortices observed in the oil-flow visualization. The careful investigation of the calculated flow reveals that the vortices are generated at the foot of the shock wave and bended downstream. It is also found that the boundary layers have a three-dimensional shape downstream of the shock wave. These flow characteristics are explained well with the simple flow model constructed by considering the wave configuration near the diffuser corner.
