在里尔机械实验室（LML, UMR CNRS 8107）风洞中进行了高雷诺数平板湍流边界层实验。该实验是在WALLTURB欧洲项目框架内与法国普瓦捷的LEA （UMR CNRS 6609）和瑞典查尔姆斯理工大学联合进行的。成功地在一个横向平面和两个垂直的立体PIV场中同时记录了143根热线。第一个SPIV平面在热丝耙上游1厘米处，第二个SPIV平面与第一个SPIV平面和壁面正交。第一个PIV结果显示，基于统计结果（即平均值、均方根和空间相关性）和潜在模型的阻塞效应似乎不会影响湍流组织。
An experiment on a flat plate turbulent boundary layer at high Reynolds number has been carried out in the Laboratoire de Mecanique de Lille (LML, UMR CNRS 8107) wind tunnel. This experiment was performed jointly with LEA (UMR CNRS 6609) in Poitiers (France) and Chalmers University of Technology (Sweden), in the frame of the WALLTURB European project. The simultaneous recording of 143 hot wires in one transverse plane and of two perpendicular stereoscopic PIV fields was performed successfully. The first SPIV plane is 1 cm upstream of the hot wire rake and the second is both orthogonal to the first one and to the wall. The first PIV results show a blockage effect which based on both statistical results (i.e. mean, RMS and spatial correlation) and a potential model does not seem to affect the turbulence organization.
