摘要:
在不同时均气相速度、初始液滴尺寸和速度脉动频率条件下，研究了气相速度脉动对JP-10液滴破碎速率的影响。计算结果表明，低时均气相速度时，小尺寸液滴较难破碎；达到破碎条件的情况下，随着脉动强度的增大液滴破碎所用时间缩短，而气相速度脉动频率对JP-10液滴破碎的影响不明显。
Abstract:
The effects of the gas phase velocity fluctuation on breakup of JP-10 droplets were investigated under different time-averaged gas phase velocity, initial droplet size and pulsation frequency. The calculated results show that the small droplet is difficult to break up when the time-averaged velocity is slow, the amount of time required to break up droplets cuts down with increase of the fluctuation intensity in the context of that the droplets can break up, and the effect of the pulsation frequency of gas phase velocity on the breakup of JP-10 droplets is not obvious.
