ツイストサボニウス風車の出力機構解明に向けた流れ場の三次元可視化解析

抄録

The twisted Savonius turbine is a kind of vertical axis wind turbine (VAWT) which have twisted shape, and the output mechanism is still unknown clearly. Many researches show the flow field around the turbine has vertical components along with the rotational axis, and we think this is a key to understand the output mechanism. In order to obtain the three dimensional flow at the wake of the turbine, we applied three dimensional color-PTV and spatio-temporal LER for interpolation of vectors. As a result of these analysis, we found the three dimensional vorticity distribution.
