LDA-Measurements of Mean Velocity, RMS-Values and Higher Order Moments of Turbulence Intensity Fluctuations in Flow Fields with Strong Velocity Gradients,

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)
