The flapping of a flag in the wind is classical fluid-structure problem that concerns interaction elastic bodies with ambient fluid. We focus on desirable experimental results flow around flag. By immersing yet self-supporting heavy into water flow, we use particle image velocimetry (PIV) techniques to obtain whole field midspan interacting fluid periodic state. A unique PIV processing method used measure near-wall velocities moving There exists thin circulation region suction side This...

This hybrid approach proposed in the present study is a mixture algorithm of 3D PTV and Tomo-PIV based on two-camera system, which able to measure flow field closed system with high refractive without situ calibration. Knowing calibration data air indices different optical media, simplified multimedia photogrammetry model established least square method. A new particle matching using concept match probability between twin image frames has been developed reconstruct physical position...
