采用仅显示环簇式塞式喷管单元间干涉激波区域网格点作为可视化方法对数值模拟结果进行后处理,得到了直观的三维干涉激波图像,并归纳得到三种干涉激波的拓扑结构和一种脊状能量泄漏区.结合文献中的实验数据分析了三种拓扑结构所造成的干涉损失,为设计提供参考. Using only the mesh points of the interferential shock wave in the annular jet nozzle unit as the visualization method to post-process the numerical simulation results, an intuitive three-dimensional interference shock wave image is obtained and three types of interference shock wave topologies are summarized Structure and a ridge-shaped energy leakage area.According to the experimental data in the literature, the interference losses caused by the three topologies are analyzed and the reference is provided for the design.
