摘要：通过实验研究了lda测量体积大小对速度数据的平均速度、速度波动均方根值和高阶统计矩的影响。将测量结果与计算结果进行了比较，模拟了不同体积尺寸下的数据统计。对于湍流速度波动的均方根值的测量，提出了一个简单的关系式来校正lda测量体积大小的影响。(作者)
Abstract : The influence of the LDA-measuring volume size on the mean velocity, rms-values of velocity fluctuations and higher order statistical moments for the velocity data was investigated experimentally. The measurements are compared with calculation, simulating the data statistics for different volume sizes. A simple relationship to correct for the effect of the LDA-measuring volume size is proposed for measurements of rms-values of turbulent velocity fluctuations. (Author)
