1329 柔軟シート上の乱流境界層

抄録

This investigation was done for understanding the effect of the flexibility of the wall on the turbulent boundary layer in a flutter state. A wind tunnel was used for the present experiment. The profiles of the mean flow and turbulence intensity on the flexible sheet were measured with a hot-wire anemometer. In addition, the displacement of the sheet was measured using a laser displacement meter. The velocity defect on the flexible sheet was larger than that on the rigid wall, and the turbulence intensity was larger.
