Abstract: We have experimentally investigated the influence of the shape near the trailing edge of a flat-plate blade on the periodic velocity fluctuation in the near wake of the single rotating blade. The results show that the characteristics of the near wake in the rotating flow field are similar to those in the uniform flow field; i. e., the periodic velocity fluctuation did not occur when the suction surface of the blade was scraped near the trailing edge, and did occur if the pressure surface was scraped. In the latter case, the two types of trailing edge separations occur. The flow always separates at the trailing edge of the blade on the suction side, while the flow separation alternately originates from two different points, i. e., from either the starting point of the scraping or from a fixed point on the scraped surface.
