摘要
根据建立的新型化学反应动力学模型,通过模拟喷注系统中氧化剂的雾化和蒸发过程,以及解决固态燃料注入方式的数学建模等,实现了对N2O/HTPB体系固液发动机工作过程的三维数值模拟。分析计算结果可知:所建模型和方法可靠且较精确。研究发现,固液发动机工作时各物理场呈现的非均匀性表明三维仿真有其必要性。
Based on the establishment of a novel chemical kinetics,numerical simulation of N2O/HTPB hybrid rocket motor＇s internal operation process was carried out through modeling the atomization and evaporation of oxidizer and the addition of solid fuel in this paper.The analysis of the solution showed that the models and methods founded were reliable and accurate.The in-homogeneity presented in physical fields pointed out the necessity of 3D calculation.
