フィールド風車回転翼面上の圧力分布測定(流体工学,流体機械) 前田, 太佳夫 MAEDA, Takao 川渕, 秀之 KAWABUCHI, Hideyuki 清水, 幸丸 SHIMIZU, Yukimaru Albert, BRUINING 社団法人日本機械学会 本文データは学協会の許諾に基づきCiNiiから複製したものである 530 Fluid Machinery Wind Turbine Blade Pressure Distribution Stall Unsteady Flow application/pdf This paper shows the pressure distribution on a rotor blade of 10m-diameter wind turbine. The pressure sensors were mounted inside the blade. The local angle of attack was measured with the use of five-hole pitot tubes at 1 chord length upwind of the blade leading edge. Comparison of the results of three-dimensional field rotor and two-dimensional wind tunnel measurements were carried out. The normal force coefficient shows good agreement at the linear range of low local angle of attack in the field and in the wind tunnel measurements. In this linear part, pressure distribution of field measurement also agrees well with those of wind tunnel measurement. The normal force coefficient at high local angle of attack in field measurement seems to show the stall-delay, where is post stall region at wind tunnel measurement. When the local angle of attack takes a value less than 15 degree, the normal force coefficient increases by the effect of the local slip angle. 日本機械学会 2004-05-25 jpn journal article VoR http://hdl.handle.net/10076/8134 https://mie-u.repo.nii.ac.jp/records/8177 http://ci.nii.ac.jp/naid/110004999456/ AN00187441 0387-5016 日本機械学會論文集.
