In this paper, the turbulence intensity of flow passing through the wire mesh and the nozzle have been investigated. The base flow after the wire mesh is keep at 3 m/s. The wire mesh used in the experiment, the wire diameter is 0.23 mm to 1.0 mm and the open area ratio is 49.6 % to 76.4 %. The wire diameter Reynolds number with respect to the wire diameter of the wire mesh is 43 to 185. As the result, the turbulence intensity of flow passing through the wire mesh is more influenced by the wire diameter than the open area ratio. The turbulence intensity of flow through the nozzle is homogenized independent of the wire diameter and the open area ratio.
