Nonstationary oblique-shock-wave reflections in nitrogen and argon: Experimental Results

Interferograms from a study on the reflection of non-stationary oblique shock-waves using a 23 cm dia field of view interferometer and a 10 cm x 18 cm hypervelocity shock tube are presented. The investigated incident shock-wave Mach number and compression corner angle ranges were 1 equal or less than Ms equal or less than 8 and 2 deg equal or less than theta sub w equal or less than 60 deg, respectively for both argon and nitrogen at an initial pressure approximately 15 torr and temperature approximately 300 K. The initial conditions as well as the accuracy with which they were measured are given. A theoretical review underlying major findings of the study mentioned is also presented.
