| 摘要: |
| 文中提出了具有液相离解反应的推进剂液滴高压蒸发模型，同时还考虑了燃气中极性气体成份对液滴蒸发的影响，并以N2O4推进剂液滴为例分析了具有液相离解反应的推进剂蒸发规律。结果表明，此类推进剂高压蒸发并不服从非液相离解反应推进剂的tb～P1/3规律。模型的提出为液体火箭发动机燃烧室燃烧过程分析提供了新的液滴蒸发理论数据和计算方法。 |

| Abstract: |
| In this paper the model of the propellant droplet evaporation with liquid phase dissociation reaction at high ambient pressure is developed，and the effect of polar gase compositions in combustion gases on the propellant droplet evaporation is taken into account. The characteristics of propellant droplet evaporation of the liquid phase dissociation reaction are analyzed by an example of the N2O4 liquid droplet evaporation. The calculation results show that this kind of propellant at high pressure evaporation does not obey the law of non-liquid phase dissociation reaction propellant. This model provides the new theoretical data and the calculation method for the analysis of the combustion process of the liquid rocket engine combustor. |
