PROBLEM TO BE SOLVED: To provide a two-dimensional wind tunnel which does not take time and cost in windproof stability test of a large structure such as a bridge. SOLUTION: In the two-dimensional wind tunnel having a flattened shape measuring flow path with a large area in the side of window for photographing and a small thickness in normal direction of a window for photographing, and visualizing the flow around a model 20 by flowing a tracer in the state the model is arranged in the measuring flow path, the model 20 is stood in almost vertical direction and cantilever-supported from below. Fluid force measuring devices 24 and 25 for measuring displacement and/or force caused in the model 20 are provided as a characteristic. COPYRIGHT: (C)2006,JPO&NCIPI
