Influence of the Variation of the Angle of Incidence in Vortex-shedding Metering
Abstract
In vortex-shedding metering not only the shape of a bluff body is important but also the angle of incidence of the bluff body plays a major role in connection with production tolerances and unsymmetrical inflow. In the present investigation the influence of different angles of incidence of bluff bodies on the measured vortex frequency and the flow around the bluff body was studied by using ultrasonic barriers and rectangular and triangular shapes with 1:1 ratio of width to length for the bluff body. It became apparent that the vortices separate at different edges by inclination of the bluff body. The results were ensured by numerical simulations.
