Abstract
The paper examines the influence of bluff body’s shape on vortex shedding stability in a liquid flow. It shows that the expansion of stable vortex existence domain enables the extension of velocity measurement range for vortex flowmeters. Numerical simulation of eddy flows generated by various bluff body shapes is undertaken with the appropriate comparative analysis of flow characteristics. A bluff body with the best flow parameters enabling the improvement of flowmeter’s measurement performance is selected.
