The current study focuses on the cavity formation induced by jet impingement with the help of numerical simulations based on a deformed mesh method. The interface between the liquid phase and gas phase separates the calculation domain into two single-phase domains, which exchange momentum data except for mass transfer. For the subsonic jet flow, the results show that the cavity depth is a decreasing function when the blowing height is increased, while the cavity diameter increases when increasing the blowing height. In addition, larger diameter of the nozzle will result in a deeper cavity because the jet flow attenuation becomes weaker. The simulation result shows good agreement with that of the theoretical equation on the cavity depth and diameter for the subsonic jet flow. In addition, the cavity formation created by the supersonic flow, which is treated as a compressible flow, can also be described by the developed model.

目前的研究重点是在基于变形网格方法的数值模拟的帮助下，由射流冲击引起的空腔形成。液相和气相之间的界面将计算域分成两个单相域，除了传质外，它们交换动量数据。对于亚音速射流，结果表明，随着吹气高度的增加，空腔深度呈递减函数，而随着吹气高度的增加，空腔直径增大。此外，喷嘴直径越大，射流衰减越弱，导致腔体越深。模拟结果与亚音速射流空腔深度和直径的理论方程非常吻合。此外，由超音速流动产生的空腔形成，
