Abstract
In this study, the aim is to clarify the essential vortex interference structure, the flow structure of the wake of the plain weave wire mesh composed of a simple repeating structure is investigated. The aerodynamic characteristics of the wake caused by the wire mesh are assumed to be due to the vortex structure formed in the wake of the wire mesh, which interferes with the jet flow from the open area, however the relationship between the two is not clear. Therefore, the relationship between the vortex structure and the jet flow from the open area was examined. As a result, it was found that the distribution trend of the slow-velocity region behind the wire is different in the longitudinal sections of the open area wake. In this longitudinal section, the slow-velocity area and the high-velocity area were alternately distributed behind the wire crossing point. On the one hand, in the longitudinal section behind the wire, the jet flow from the side of the wire was found. This jet is guessed to be related to vertical vortex of the wake. And, both jets were confirmed to be homogenized in the wake about 10 times the wire diameter.
