| 摘 要： | 本文采用不同数目和布置的测点对十余种不同类型和大小的稳态压力畸变和以压力紊流度表征的动态畸变流场进行了测量,得到了其流场的紊流度分布。文中对所测得的平均紊流度、紊流度的平方平均值及定义的不均匀分布度D值进行了分析,得出了测点的数目和布置对紊流度测量的影响,从而为工程上紊流度的测量提供参考。

| Abstract: | Some results of the dynamic pressure distribution measured with different transducer arrangements and produced in the lip-inlet simulator are given in this paper. A general conclusion drawn from the results is that for a typical dynamic pressure distortion, 4 rakes of 3 transducers each is the minimum number required and preferable arrangement of transducers for reasonably accurate measurements. |
