摘要: 在主、副气流各组份的流量比不变的情况下，改变输入氧碘化学激光器（COIL）光腔总气流流量，数值模拟给出了COIL拉伐尔喷管主、副气流混合状况和各物理量的分布等，通过对这些结果进行对比分析得出：输入COIL光腔总气流流量增加三倍，氧碘气流的混合状况稍稍变差，但Mach数和密度等的分布和变化规律基本不变。Abstract: The circumstance of primary flow mixed with the secondary flow, and the distribution of the physical variables describing the flowfield are studied by varying the flowrate with the same composition of primary and secondary flow. The conclusion is obtained by comparing and analyzing these results, that the state of primary flow mixed with the secondary flow becoming worse, but not very worse, and the distribution of Mach number and mass density being almost not changed with the flowrate increased to 3 times.
