提纲式地阐述固体火箭发动机气体动力学,特别是二相流的发展和应用.认为气体动力学是固体火箭发动机理论设计、性能计算和专题研究的重要基础,流场计算已成为固体火箭发动机设计和研究中众所瞩目的中心问题.提出了固体火箭发动机流场计算一体化的观点.反应湍流边界层理论是固体火箭发动机气体力学的新领域.轴对称二相流的理论和实验研究已取得显著成果,但有必要继续进行和不断完善.工程应用迫切要求从速建立许多研究专题的二相模型.三维、二相、计算气体动力学是今后发展的方向;它与固体火箭发动机一体化工作过程的计算机图象显示相结合,将成为本世纪90年代及21世纪初的新水平.
The outline and application of solid propellant rocket engine gas dynamics, especially two-phase flow, are summarized.Gasodynamics is considered as an important basis for theoretical design, performance calculation and special research of solid propellant rocket engines. And the central issue that has drawn much attention in the research, the integration of flow field calculation of solid rocket motor is put forward.The reactive turbulent boundary layer theory is a new field of gas mechanics of solid rocket motor.The theoretical and experimental research of axial symmetrical two-phase flow has been made Significant results, but there is a need to continue and continue to improve.Engineering applications urgently required the establishment of many research projects as soon as possible two-phase model.Dimensional, two-phase, the calculation of gas dynamics is the future direction of development; it with the solid rocket motor integration process The combination of computer graphics will be a new level in the 1990s and early 2000s.
