A narrow generator plate (10) is immersed parallel to the direction of flow of a fluid stream (14) for generating Karman vortices (54). In one embodiment the generator plate (10) has a shedding section wherein an aperture (26) intersects side surfaces (20) of the generator plate (10) at shedding corners (32). A further embodiment includes a generator member (36) mounted on a leading edge (16) of a generator plate (10). A modification includes a surface disruption (52) for generating boundary-layer turbulence in the fluid stream. |
