Propagation of shock waves in dilute bubbly liquids (4th report, comparison between theory and experiment for a uniform bobbly mixture)

摘要

Transient shock wave phenomena in a liquid containing non-condensable gas bubbles are studied experimentally and numerically. In order to obtain a uniform spatial distribution of bubbles experimentally, an upwardly directed bubbly flow, whose initial gas volume fraction is 0.2/100, is generated in shock tube. The liquid used is silicone oil. Nitrogen, argon, and SF_6 gas bubbles are tested to show the thermal effects of the bubble interior.
