摘要

摘要通过实验研究了二次气体注入对通过轴对称马赫数为 2 的喷嘴的流动的影响。实验是在喷嘴压力比为 5 时进行的。本研究选择的二次喷射位置为 Ls = 0.5Ld 和 0.75Ld，二次气体喷射的二次压力比 (SPR) 为 0.5、1.0 和 1.5。结果发现，以 0.5 Ld 注入时，在所有 SPR 下喷出的气流都不会偏转。当注入 0.75 Ld 时，SPR 值为 0.5、1.0 和 1.5 时，气流分别偏转了约 5.50、5.50 和 100。这些流动偏转仅在注入平面内观察到。在二次注入的法线平面上没有观察到二次注入的影响。

Effect of secondary fluid injection on flow through supersonic nozzle

Abstract

The effect of secondary gas injection on the flow through an axisymmetric Mach 2 nozzle is studied experimentally. The experiments were conducted for a nozzle pressure ratio of 5. The secondary injection locations chosen for this study were L_s = 0.5L_d and 0.75L_d, and the secondary gas was injected at secondary pressure ratios (SPR) 0.5, 1.0, and 1.5. It is found that for injection at 0.5 L_d, the flow emanating is not deflected for all SPRs. For injection at 0.75 L_d, the flow is deflected by about 5.5⁰, 5.5⁰ and 10⁰, for SPRs 0.5, 1.0, and 1.5, respectively. These flow deflections are observed only in the plane of injection. The effect of secondary injection was not observed in the plane normal to the secondary injection.
