Original data for the combined PIV/LIF measurement of a turbulent jet at a Reynolds number of 2000

This data set contains the original data for the combined PIV/LIF measurement of a turbulent jet at a Reynolds number of 2000.<br>This data was originally used to determine the mixing in a turbulent jet, but its main use was for the investigation of the mechanics of the turbulent/non-turbulent interface and the entrainment process. For this purpose measurements were carried out with combined particle image velocimetry (PIV) and laser-induced fluorescence (LIF). All data is contained in a Matlab data file (*.mat). PIV data are in pixel [px] units; LIF data are normalised relative to a calibration concentration field.

本数据集包含雷诺数（Reynolds number）为2000的湍流射流的联合粒子图像测速（particle image velocimetry, PIV）与激光诱导荧光（laser-induced fluorescence, LIF）原始测量数据。
该数据最初用于表征湍流射流的混合特性，但其核心应用为研究湍流/非湍流界面的力学机制与卷吸过程。为此，研究团队采用PIV与LIF联合测量方案开展实验，所有数据均存储于Matlab数据文件（*.mat）中。其中PIV数据以像素（pixel, px）为单位，LIF数据则基于校准浓度场完成归一化处理。
