| 摘 要： | 为了进一步探究凹腔火焰稳定器内的流动特点,设计了一个简单的小型超音速风洞。并在此基础上,通过油流显示法对矩形凹腔和人字形凹腔的内部流动进行了实验观察,并将实验结果与数值模拟结果进行了对比,获得了矩形凹腔和人字形凹腔内的流动信息,结果表明:人字形凹腔内部气流有明显的向中心汇聚的趋势。实验为数值模拟提供了依据并为进一步的实验打下了基础。

| Abstract: | A supersonic wind tunnel was designed for further investigation of the airflow in cavity flam houder.On this condition,method of oil-flow display was used for observing the flow in the cavities,and obtaining the information of the flow.The results show that the airflow inside the herring-bone cavity had obvious trend of flowing to the center line.The experiment had provided a evidence for numerical simulation and further experimental investigation. |
