摘要: 激光点火技术是一种新型点传火技术,为了研究激光多点点火对膛内压力波动、燃烧稳定性等的影响进行了数值模拟。以某短身管30 mm火炮激光点火过程为研究对象,建立了二维两相流数学物理模型,采用MacCormack两步预估校正差分格式及“运动控制体”运动边界处理方法实现数值计算。数值计算结果与实验有较好的一致性,对激光点火系统设计具有参考意义。

Abstract: Laser ignition technology is a new launch technology. The numerical simulation is carried out to investigate the influence of multi-point laser ignition to the pressure wave and abnormal combustion of the propellants. A two-dimensional two-phase flow model of multi-point laser ignition in a short-barrel gun is established. Numerical simulation is conducted by MacCormack predictor-corrector scheme and the movable boundary conditions are obtained by movable control volume method. The numerical calculation results are consistent with those of the experiments. It has good value for laser ignition system design.

Key words: fluid mechanics, laser ignition, numerical simulation, two-dimensional two-phase flow
