| 摘 要： | 通过一系列对比实验比较了隔板对气流转捩点、总压损失、光腔静压的影响，并通过分析阐述了竖直隔板对扩压器内部气流参数产生影响的原因。隔板可以增加超音速区域的长度，并能增加光腔压力分布的稳定性，减小总压损失，增加压力恢复系数；隔板厚度对光腔静压的影响较大，需严格控制隔板厚度以避免正激波的产生。

| Abstract: | A series of contrast experiments were done to obtain the influence of vertical vane on flow inflexion, the loss of stagnation pressure and cavity static pressure. The cause of influence of the vane on diffuser flow field is expounded by analysis. The vane can increase the length of supersonic region, the stability of cavity pressure, and reduce the loss of stagnation pressure thus to increase the pressure recover coefficient. The vane thickness has great influence on cavity static pressure, so the thickness must be controlled to avoid coming into being the normal shock. |
