基于莫尔层析技术诊断不完全膨胀的三维流场

Diagnostics of 3-D underexpanded free jets of air by moire-layer upon layer method

基于莫尔层析技术 ,诊断了从不同喷嘴喷出的对称与非对称不完全膨胀气流的密度分布。给出了实验结果 ,并对该结果分析后 ,得到几个重要结论 ,最后 。

Using the moire-layer upon layer method for symmetric and asymmetric flow fields density distributions of underexpended free jets of air from differential nozzles have been measured.A few experimental results and important conclusions are show,system′s applications are reviewed.
