 note = {本研究では、回転翼上の非定常圧力の計測法を確立し、貫流羽根車翼上の圧力の基本特性を明らかにする。具体的に述べると、複雑なケーシングのない簡単な形状を有する貫流羽根車を対象として、動翼表面の非定常圧力測定を試みる。そして、その結果を、流れの可視化、および、粒子画像速度計(以後PIV)による測定、熱線流速計(以後HW)による測定、数値計算による結果と比較し、考察する。その結果、位相平均手法を用いることで、一周期間の翼表面での圧力変動を明らかにした。本実験結果は、数値解析のベンチマークとしても有効であろう。, In the present research, we develop the measuring technique of unsteady pressure on a rotating blade surface, and reveal the basic features of a cross-flow-impeller pressure. Specifically speaking, we consider the simplest model for the fundamental study, namely, the flow around the cross-flow impeller rotating with flat-plate blades in open space without any casings. On this impeller's blade, we measure the fluctuating pressures, which are discussed in comparison with flow visualizations with the particle-image velocimeter (PIV), velocity measurements by a hot-wire velocimeter (HW) and numerical simulations. As a result, we get accurate pressures on the rotating blade, which are conditionally-averaged over a number of periods. The obtained experimental results can be also dedicated to CFD as standard benchmarks., application/pdf},
