稳态和非稳态漩涡发生器喷射分离边界层的相位锁定流体测

Vortex generator jets (VGJs) have been found to be an effective method of active separation control on the suction side of a low pressure turbine (LPT) blade at low Reynolds numbers. The flow mechanisms responsible for this control were studied and documented in order to provide a basis for future improvements in LPT design. Data were collected using a stereo PIV system that enabled all three components of velocity to be measured. 德国LaVision PIV/PLIF粒子成像测速场仪 Imager sCMOS PIV相机 用于粒子成像测速(PIV)的荧光示踪粒子
