| 摘要: |
| 对-甲基肼的高压蒸发进行了研究，计算了-甲基肼液滴温度和半径的变化历程，并对各种不同环境压力下的结果进行了比较。计算了蒸发常数、传热数和传质数，所 得结果同已有的实验数据相比较是吻合的，且考虑了不同的 Le 数对蒸发界限压力的影响，说明了此蒸发模型和计算方法的合理性。所得结论对于分析液体火箭发动机的燃烧过程是重要的。这一方法还可以用来计算其他燃料的蒸发。 |

| Abstract: |
| Evaporation of monomethyl hydrazine(MMH)at high pressure is studied. The MMH droplet radius and temperature at different environmental pressure is computed and compared. The evaporation constant. the number of heat transfer and the number of mass transfer.are considered and computed. The results are identical to the test data. The effect of Lewis number to the limit pressure of evaporation is evaluated. It shows that the evaporation model and compute method are reasonable. The results are important for the analysis of the combustion process in liquid rocket engine. This method may be used to evaluate other fuels. |
