用气泡生成理论模拟闪急喷射的研究

Simulation of the flashing boiling injection with the bubble growth theory

用气泡生成理论对闪急喷射的气泡生长过程进行了数值模拟，分析了燃油喷射压力对气泡生长过程的影响；用该理论与传统喷射过程的喷雾贯穿距离计算相结合，对闪急喷射的贯穿距离进行了数值计算。

The Simulation of the bubble growth process of flashing boiling injection is made with the theory of bubble growth. The effects of fuel injection pressure and overheat on the bubble growth are analyzed. The penetration of flashing boiling injection is also calculated by the combination of the bubble growth theory with the conventional spray calculation. The calculation results are generally compatible with the experiment.
