摘要：

The Wells turbine has a cascade whose stagger angle is 90 degrees, that is, the blades are perpendicular to the axial velocity. Good performance is required from 0 degrees to 90 degrees of the angle of attack because the turbine is operated in the oscillating airflow produced with wave energy. Further, very interesting and complex flows are experimentally observed by the oil-film method in the large angle of attack where the performance is strongly influenced, especially the self-starting aspect. This paper tries to analyze the mechanism of these 3-dimensional flows around the turbine with numerical analysis, focusing on the off-design condition.
