| Studies of the law of high-speed gas jet interaction with liquid basedon the reviewed and summarized of researches' developments in the world.Bulk-loaded liquid propellant gun and liquid propellant electrothermalchemical launch are as the engineering project background of it. The mainpoints are follows:The experimental of single-plasma jet interaction with liquid has beendeveloped. By using a High-speed camera, expansion process of the plasma jethave been records. The influences of discharge voltage, chamber structure toplasma jet shape has been approached.The experimental of high-speed twin-gas jet interaction with liquid hasbeen developed. High-speed camera is used to record the expansion process ofthe twin-gas jet. Got the law of high-speed gas jet interaction with liquid, and the change law of parameter in the flow field. The influence of nozzlehole diameter,dual-orifice interval,jet pressure and chamber structure tojet shape has been approached.The theoretical studies of gas jet interaction with liquid were developedbased on the experiment. Two-dimension axisymmetric models of the unsteadyprocess of plasma jet and twin-gas jet interaction with liquid are developedand solved by the commercial software FLUENT. The change law of parameter inthe flow field has been obtained.
