| Popis: | Particle Image Velocimetry (PIV) measurements were performed around two kinds of three dimensional building models those were placed in a wind tunnel. Special attention was paid to uniformity of emitting tracers and clearness of images. For a cubic model, flow separation around frontal corner and vortexes in front of and behind the model is observed in measured results. For a street canyon model, a vortex in the canyon is clearly shown. It was confirmed that PIV technique is very effective to measure the complicated velocity field around buildings in detail in a wind tunnel. |
