| 摘 要： | 在简要描述使用最大熵原理预测初始雾化液滴分布的基础上,发展了较传统方法具有更大收敛域的数值计算方法,建立了离心式喷嘴雾化特性研究实验台,使用激光相位粒子分析仪进行了雾化粒径分布研究,结果显示实验数据同使用最大熵原理预测的分布吻合性较好,在此基础上最后提出了在液体火箭发动机雾化粒径分布预测应用中的策略。

| Abstract: | The method based Maximum Entropy Principle for prediction of droplet size distributions of primary atomization in liquid rocket engine is described and a developed numerical method is introduced. A study of swirl atomization characteristics is accomplished by using PDPA after an centrifigual type experimental system of atomization characteristics was built. The results show that the prediction value and the experimental data are in good accordance when compared with experimental data, therefore the strategy of applying the method for liquid rocket engine is presented. |
