Measurement and calculation of shock attenuation in a channel with perforated walls
Abstract
The velocity of a shock wave generated in an air/air shock tube with perforated walls is measured by means of an optical Doppler schlieren technique. The attenuation of the shock is measured for perforation ratios varying between 0.1 and 0.5 and over a length of about 40 channel heights. Various numerical models are used to determine the shock attenuation, and these results are compared with the experimental data.
