| 摘 要： | 在保持主气流流量和副气流中I2的流量不变的条件下，改变副气流中He的流量，数值模拟氧碘化学激光器拉伐尔喷管内的流场混合特性。结果表明，随着副气流中He的流量的增加，副气流垂直穿透主气流的深度逐渐变大，主、副气流混合状态也逐渐变好，直至氧碘气流混合均匀。

| Abstract: | The circumstance of primary flow mixed with the secondary flow are numerically simulated by varying the flow rate of He in the secondary flow with the same primary flow and the same flow rate of I2 in the secondary flow. The conclusion is obtained by comparing and analyzing these results, that the penetration depth of the transverse secondary flow in the primary flow extends and the state of primary flow mixed with the secondary flow becomes better with the flow rate of He in the secondary flow increased, until the primary flow and the secondary flow are well distributed. |
