Interaction between the reflected shock wave and the unsteady jet in a shock tube experiment - Theoretical base and proof for the behavior of a reflected shock wave
Abstract
The nonuniform unsteady mixing process in the compressed high-temperature field generated by an unsteady jet of fuel gas is clarified, expanding on the study of Ishii et al. (1984). The results confirm the previously calculated values of the back of the apex of the hemispherical reflected shock wave. An unstable hemispherical shock wave reconverting to a stable normal shock wave is shown to generate expansion waves, causing a temporary pressure drop (of about 120 mirosec) in the Kistler transducer on the side wall following the passage of a reflected shock wave. The calculated results are in agreement with previous experimental data, and they show that a strong inverse flow is produced by the interaction between the reflected shock wave and the jet behind the reflected shock wave.
