spray

Spray instantaneous momentum is obtained by measuring the impact of pressure sensor; total momentum of spary can be also obtained by summing the instantaneous momentum of one spray process.

介绍了一种利用动量的观点来研究燃油的喷射过程的方法 ,即根据动量定理 ,利用传感器测量油束撞击传感器上的力的变化来得到油束的瞬时动量 ;通过对一次喷油过程中的动量求和 ,便可计算出冲击到传感器上油束的总动量。

Based on liquid sheet model, surface wave breakup theory and KIVA3 code, a spray model is developed for gasoline direct injection (GDI) engines high pressure swirl injector.

该油束模型与实验结果吻合良好。
