摘要
依据LPG沸点低的特点,在FIRE8.42软件平台下建立瞬时蒸发模型,模拟LPG自由喷雾过程,得到LPG缸内直接喷射的油滴尺寸、温度以及油滴的贯穿距等参数的特性。通过与试验结果对比,表明瞬时蒸发模型符合实际情况。
Aiming at low boil temperature of LPG, the author applied the flash evaporation model to simulate the evaporation of LPG, and found the character of drop sizes, temperature, gas fuel vapor mass fraction as well as penetration length and so on. Comparing with the test result, the flash evaporation model is in accord with the fact.
