| Abstract: | In the paper, a new mathematical model has been developed. The Level Set method has been employed to gas-water interface successfully. And then, the flow field of injection of gas jets into water has been numerically simulated. The evolution of the high-pressure and underexpanded gas jets in water has revealed some important physical phenomena, such as the water-gas interaction, shock wave structure, and gas bubble formation. In this paper, we have simulated the gas jets in water considering the gas and water coupling for the first time. The qualitative conclusion agrees the with experimental results. |
