| 摘 要： | 利用水平集(Level-set)方法和最小距离函数(MDF)方法,对固体火箭发动机装药燃面退移问题进行研究。基于Level-set方法和MDF方法的相互耦合,建立了一种可以准确预测固体推进剂装药燃烧表面退移的方法;对不同几何药型、不同燃速组合推进剂装药及带侵蚀效应的装药进行计算分析,其结果表明,该组合方法及所采用的网格界面分割和几何重构计算燃面面积的思想,在预测固体推进剂装药燃面瞬态退移问题上具有良好的适应性和较高的可信度。

| Abstract: | The combustion surface regression is studied using Level-set method and minimum distance function (MDF) in SRM.A way that accurately predicts burning surface regression of solid propellant is established based on Level-set method and MDF.The grains with different geometries,the propellant grains with different burning rates and the grains with erosion combustion are calculated and analyzed.The results show that the combined method which calculates the burning area based on interface segmentation and geometric reconstruction has a good adaptability and high reliability on combustion surface regression. |
