论文摘要
我们研究了通过视力（LOS）配置的湍流传播的声波传播的相波波动的统计。实验是在封闭的von karman旋转流量上进行的，该旋转流的边界保持在恒定温度下。特别是，我们分析了相波的均方根（RMS）和功率谱密度（PSD）。开发了模型，并使用几何声学对这些数量获得的分析预测显示与实验观察一致。
We investigate the statistics of phase fluctuations of an acoustic wave propagating through a turbulent flow in line of sight (LOS) configuration. Experiments are performed on a closed von Karman swirling flow whose boundaries are maintained at a constant temperature. In particular, we analyze the root mean square (RMS) and the power spectrum density (PSD) of phase fluctuations. A model is developed and analytical predictions obtained for these quantities using geometrical acoustics are shown to be in agreement with experimental observations.
