240 ジャイロミル形風車の周りの流れの解析(S41-1 移動境界・連成(1),S41 移動境界・連成・振動と騒音問題)  [in Japanese] 240 Flow Analysis around Gyro-Mill Type Wind Turbine  [in Japanese]

In this research, flow fields around Gyro-Mill type wind turbine were simulated at Re=4×10^3 by numerical method. Numerical results has shown that the rotation of the wind turbine is more difficult to be generated as Reynolds number decreases, because of a low lift/drag ratio at the low Reynolds number and an interference between blade and vortices. The torque coefficient could be varied from negative quadrant to positive quadrant utilizing a pitch control method based on a knowledge found by an analysis of drag type wind turbine.
