| Abstract: | In order to investigate the expansion characteristics of the high pressure combustible gas jet in a bulk-loaded liquid and to explore the control methods for improveing the jet stability,a cylindrical four-stage stepped-wall chamber was designed.Using a high-speed kinescope system,the expansion and mixing process of the gas jet in the liquid was observed.A series of photos describing jet expansion form were obtained,the expansion velocity of the Taylor cavity was measured and the effects of the chamber wall... |
