| 摘 要： | 近年来,我们对轴对称紊流发生器进行了一系列的研究。本文主要介绍畸变流场的调节规律,并分析了在试验范围内畸变指标的测量精度。基于缺乏瞬态畸变的测量手段,并考虑到目前国内使用的畸变指标,本文采用稳态畸变指标(?),DC90和紊流度T_(Av)作为特性参数。

| Abstract: | This paper provides a regulation law for distortion flowfield by axisymmetric turbulence generators, which can meet the demands for simulating the static and dynamic inlet distortions simultaneously. The distortion flowfield is regulated by variation of throat area ratio and working pressure ratio. The experiments show that the absolute deviation of the turbulence regulated by this law is less than 0.01. |
