並列２平板後流に及ぼすレイノルズ数の影響

抄録

An experimental study on the effect of Reynolds number (Re) on the flow normal to the two parallel flat plates was conducted by varying the gap ratio using the wind tunnel. For each of the Reynolds numbers velocity component were measured by using hot-wire anemometers and result were recorded. The interference of the wake on the downstream flow of two parallel flat plates were analyzed and expressed in the form of Strouhal number and pressure coefficient. Most of the cases show that the Strouhal number distribution was almost equally distributed at the range of 3000 ≤ Re ≤ 30000 except at lower Reynolds number of Re < 7000. Also, the pressure coefficient distribution slightly becomes unstable at relatively lower Reynolds number.
