“…Unlike traditional methods, their method was capable of reducing or eliminating noise, increasing sensitivity of sensors (which allowed the application of a smaller bluff body, thereby reducing the pressure drop in the flowmeter), and decreasing measurement uncertainty. Vengupal et al conducted a fundamental study into the effect of pipe on shedding characteristics generated after the bluff body. They investigated the relationship between Strouhal number and Reynolds number in different flow regimes, such as chaotic laminar flow, transition regime, and turbulent flow.…”

Vortex flowmeter has broad applications in industrial single-phase flow problems. There is experimental evidence suggesting that the presence of particles in gas-solid flows may cause a modulation in the turbulence intensity of the carrier phase. Using vortex flowmeter, one may manipulate vortex shedding generated by a bluff body and, therefore, change pressure fluctuation after bluff body and pressure drop between two sides of the vortex shedder. In this research, a vortex flowmeter with a differential pressure sensor was used to experimentally measure solid mass loading in a dilute gas-solid two-phase flow. The results indicated that the average bluff body pressure drop in gas-solid flows is always more than that occurring in gas flows, and the presence of particles can both attenuate and augment vortex shedding frequency. The results also showed that one can obtain the solid mass loading by means of pressure drop signals with a maximum relative error of 5%, which may be advantageous for industrial process measurement.KEYWORDS differential pressure, dilute gas-solid two-phase flow, solid mass loading measurement, vortex flowmeter
