Abstract
The vortex generating device includes a narrow generator plate which is immersed in a fluid flow to generate Karman Vortices. The generator plate is oriented with an axis of elongation parallel to the direction of flow of the fluid stream. The generator plate has side surfaces essentially parallel to the direction of fluid flow. The side surfaces have a shedding region where an aperture intersects the side surfaces to form a leading aperture edge which serves as a shedding corner at which vortices detach from the generator plate. The aperture further intersects a trailing edge of the generator plate. The aperture includes the leading aperture edge, which may be either curved or linear, and an aperture portion which extends from the leading aperture edge to a point where it intersects the trailing edge of the generator plate. The device is used with sonic detection appts. having transducers mounted on the flow channel walls.
