本文描述了一个测定粘性亚层大涡流动力学的实验。利用Lumley正交分解法对部分均匀流和静止流进行正交分解，从实验交叉谱数据中确定涡旋结构。实验是在专门为这项研究设计的甘油隧道中进行的。广泛的交叉光谱（16000）测量与微型分裂膜探针。本文包括对设备的描述，对探针响应的详细分析，对数据处理过程的描述，以及对所产生的分解涡流的解释。
An experiment to determine the dynamics of the large eddies of the viscous sublayer is described. Lumley’s orthogonal decomposition for partially homogeneous and stationary flow is to be used to determine the eddy structures from the experimental cross-spectral data. The experiment is carried out in a glycerine tunnel designed specifically for this investigation. The extensive cross-spectra (16,000) are measured with miniature split film probes. Included in the paper are a description of the facility, a detailed analysis of the probe response, a description of the data processing procedure, and finally an interpretation of the resulting decomposed eddies.
