Measurements up- and downstream disc-attached cylinder near wall

The dataset contains laser Doppler velocimetry (LDV) of the flow around a circular cylinder with a disc attached near the wall. The flow velocity is measured up- and downstream of the disc-attached structure. 
The probe was positioned in four different positions: horizontal, vertical, 45 and 135 degrees relative to the horizontal axis. The time series of the measurements are provided in 'dataseries.mat' together with the corresponding arrival times and the x-, y-, and z-positions. The mean values of the velocities are calculated in 'YZ.mat' together with the positions.

该数据集收录了绕带圆盘的激光多普勒流速仪（LDV）测量数据，圆盘紧贴壁面。流速在圆盘附着结构上游和下游进行测量。探头被置于四个不同位置：水平、垂直、与水平轴成45度和135度。测量数据的时序信息、相应的到达时间以及x、y、z位置信息均包含在'dataseries.mat'文件中。流速的平均值及其位置信息则计算并存储在'YZ.mat'文件中。
