437 格子配列された9円柱まわりの流れの研究(G05-9 複雑流れ(2),G05 流体工学)  [in Japanese] 437 A Study of Flow around a Square Array of Cylinder  [in Japanese]

In this paper, flows around a square array of nine cylinders are investigated. The pressures on the surface of cylinders are measured by experiment of the wind tunnel. The effects of distance between neighboring cylinders on pressure distribution are investigated and several flow patterns are found. Some numerical results are obtained from computational simulation and compared with the experimental ones.
