相互干渉渦流れ場における二円柱まわりの流れ特性

抄録

In order to understand the aspect of flow around two circular cylinders, the pressure on the circular cylinder surface was measured. The single tube manometer was used for measurement of the pressure, and image processing in a computer was introduced into reading of the scale. The pressure measurement experiment was performed by the low flow velocity which is performed by flow visualization. The Reynolds number based on the circular cylinder diameter D and the flow velocity U was Re=2500. Surface pressure distribution of the circular cylinder was investigated for every arrangement pattern of two circular cylinders, and the flow characteristic was obtained. The drag coefficient C_D was calculated from distribution of the measured pressure coefficient C_P.
