As a compact device, the converging-diverging vortex flowmeter is proposed and designed, and its performance is studied experimentally. It is found that, first of all, an up to 51% extension of the lower measurement limit can be realized through the converging-diverging structure, compared with conventional vortex flowmeters; second, the converging-diverging vortex flowmeter with a trapezoidal bluff body has a larger Strouhal number and smaller pressure loss. The results suggest that the converging-diverging vortex flowmeter provides an alternative device especially suitable for the measurement of low-velocity fluids.}, type={Artykuły / Articles}, title={Design and Performance of the Converging-Diverging Vortex Flowmeter}, URL={http://journals.pan.pl/Content/89753/PDF/Journal10178-VolumeXVIII%20Issue1_12%20paper.pdf.pdf}, doi={10.2478/v10178-011-0012-5}, keywords={vortex flowmeter, converging-diverging structure, lower limit of measurement, Strouhal number, drag coefficient}, }
