Experimental Study of Pulsed High-Speed Liquid Jet

- 論文の詳細を見る
Pulsed liquid jets with speeds ranging from 100 m/s to 1000 m/s were produced using a gas gun. Kerosene, water and alcohol were injected into ambient air by the impact of a projectile driven by the gas gun operated with high-pressure helium. Jet speed was measured by output signals generated when the jet cut two laser beams at the exit of the gas gun. Double exposure holography interferometry visualized the shock wave generated in front of a supersonic jet as well as the moving jet shape. Interesting phenomena associated with jet motion and the impact of the jet on the solid surface were observed. Jet generation time and evolution of the jet shape was measured. The effect of the nozzle size on the jet speed was studied. Experimental findings indicate that the formation of a precursor jet and a bifurcated jet largely depends on the liquid-air surface tension.
