An interferometric investigation of shock structure and its induced shock-tube boundary layer in ionized argon
Abstract
The structure of ionizing shock waves and their induced boundary layers in argon have been studied experimentally in the UTIAS 4 inch x 7 inch hypervelocity shock tube using dual-wavelength interferometry. The relaxation lengths and transitions of shocks of Mach numbers 16.5 and 13.5 for initial gas pressures of about 5 torr have been measured at 2cm and 8cm, respectively. The transition profiles and relaxation lengths are in reasonably good agreement with analysis.
