風車回転翼面上の圧力分布に関する研究 : 第3報,ヨー流れ状態の翼に作用する空気力(流体工学,流体機械) 鎌田, 泰成 KAMADA, Yasunari 前田, 太佳夫 MAEDA, Takao 藤岡, 秀康 FUJIOKA, Hideyasu 鈴木, 潤 SUZUKI, Jun 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 Yawed Inflow Pressure Distribution application/pdf This paper shows the results of the pressure distribution measurements on a rotor blade of horizontal axis wind turbine in case various yawed operation. The experiments are carried out in a wind tunnel with 2.4 m-diameter test rotor. In the measurements the power curve and pressure distributions are measured for each azimuth angle. Increasing of yaw angle, the power coefficient of the rotor decreases. The sign of yaw angle does not have any effect on the power performance. The aerodynamic forces are discussed by using axial and rotational force coefficients in each azimuth angle. In case of higher tip speed ratio, the blade section passing upstream side for yawed operation shows better contribution to the rotor torque than that of downstream side. In this tip speed range, the aerodynamic forces for 70% radius section seem to proportional to the attack angle. In case of lower tip speed ratio, the blade in downstream side does not contribute to rotor torque, and it seems to result from the separation. 日本機械学会 2007-03-25 jpn journal article VoR http://hdl.handle.net/10076/8701 https://mie-u.repo.nii.ac.jp/records/8167 http://ci.nii.ac.jp/naid/110006271364/ AN00187441 0387-5016 日本機械学會論文集.
