This paper deals with flow-profiles around an enlarged solid model of netting which was set into an experimental flume tank on every half angle of Θ, (range from 0 to 3Θ of setting angles), to clarify flow distribution around the model. In this case Θ means the angle of attack when mesh-hall faded out from the projective plane. A thin film flow-meter with corn shaped probe was used in the experiment. Measurements were carried out on 110 fixed points, 24 points around mesh, and 5 points inside mesh-halls at every attack angles on a horizontal plane. The flow-speed was maintained at 10 cm/s, and Reynolds number at 1.9×10^3. From the resultant profiles, the fluid-dynamical force acting on each leg was similar with the case larger than 3Θ of attack angles.
