EXPERIMENTAL OPTIMISATION OF BLUFF BODIES IN ULTRASOUND VORTEX SHEDDING FLOW-METERS

H. Windorfer, V. Hans

Abstract

Using ultrasound in vortex shedding flow-meters is a powerfull combination. The high sensitivity of ultrasound to the vortex structures enables a compleatly new design of the measuring system. Smallest bluff-bodies can be used generating a regular and well defined vortex street. At the same time the pressure loss caused by the bluff-body is minimised. The high sensitivity of ultrasound to the vortex structures and the secondary vortices requires the design of a special shaping with new properties.
