Abstract

In this paper shearing interferometry as used at the Prins Maurits Laboratory for studying shock wave diffraction around structures is reviewed. The performance of the shearing interferometer is illustrated by a number of applications. It is shown that, for not too complicated flow geometries, accurate density distributions of the flow field can be obtained from an analysis of the recorded interferograms. A comparison of results obtained with a numerical code, based on the flux-corrected transport (FCT) method, and experimental data also are presented.
