用立体粒子成像测速(PIV)方法对空气幕帘下方站立的模特

The flow of an air curtain mounted above a doorway in which was placed a mannequin was studied using stereo particle image velocimetry. The study revealed that the interference of the air curtain flow was limited to a region near the doorway. The air curtain flow stagnates around the top surfaces of the mannequin. A high level of turbulence also existed in this region. The turbulence diminished rapidly past the mannequin and increased in a thin region near the floor as the flow entered the floor vents 德国LaVision PIV/PLIF粒子成像测速场仪 Imager SX PIV相机 用于粒子成像测速(PIV)的荧光示踪粒子
