2D and 3D numerical simulation results of vortex flowmeter under nonideal installation conditions
W. L. Chen, J. Mu
Abstract:
An air test line of 50mm diameter was used in experiments covering two kinds of straight pipe length, and the numerical simulation results of vortex shedding frequency, which originated from the ANSYS FLUENT analysis results, were proved to be highly consistent with the experimental results. Based on this comparison, flow field simulation studies, including 13 pipe conditions, were carried out to establish the effect of upstream and downstream elbow fittings on the performance of the vortex flowmeter. The results indicated that the influences of the upstream straight pipe length were more obvious than the downstream straight pipe length. When there was an upstream elbow, the frequency value was greatly reduced, and the maximum error was -60.62%. The closer the elbow was to the vortex generator, the larger the decrease. The downstream elbows had a relatively small influence on the measurement results, and the maximum error was -13.23%. Considering the asymmetry of the 2D pipeline, the 3D simulations of part of the pipeline condition were further executed. The differences between 2D and 3D calculation results were analyzed, and the application value of different simulation results was explored.
