Paper Abstract

We have studied wave curl structures created behind the shock wave as it expands beyond the edge of the shock wave tube. A description of a large-scale shearing interferometer used for these studies is presented. A technique for quantitative automated analysis of the shearing interferograms is developed, which is well suited for registration of the interferograms using CCD sensors and data processing using PC. Physics of the gas-dynamics processes is analyzed. Main quantitative parameters of the gas are presented.
