Abstract:
Vortical flows are mostly considered as disturbances, however, in a vortex-shedding flowmeter controlled vortex shedding from a bluff body is used for throughflow metering. In this case, any additional vortices, swirl, or pulsations introduced upstream will interfere with the meter’s function. In the present work, the effect of inflow vortices on the accuracy and function of a vortex-shedding flowmeter are investigated numerically. The inflow vortices are induced by a single and double bend positioned upstream of the bluff body. The resulting flow is analyzed using visualization and DFT for various types of bluff bodies.
