本文介绍了一种考虑空穴后的喷油过程模拟方法。计算得的嘴端压力比不考虑空穴时更符合实测值,这一模型也计算出了二次喷射的波形,但尚须作进一步的改进,以便更好地预测二次喷射。
This paper presents a method of simulating the injection process after hole injection. The calculated tip pressure is more in line with the measured value than without considering the hole. The model also calculates the waveform of the secondary injection, but further improvement is needed to better predict the secondary injection.
