Abstract

Vortex flowmeter adopts advanced micro processing technology, which has the advantages of strong function, wide flow range, simple operation and maintenance, convenient installation and use. It is widely used in petroleum, chemical industry, electric power, metallurgy, urban gas supply and other industries to measure various gas flows. In order to study the characteristics of the inner flow passage of the vortex flowmeter and reach the normal working standard of the vortex flowmeter, this paper uses CFX to calculate the turbulent kinetic energy, eddy viscosity and flow velocity of the inner flow passage of the vortex flowmeter and analyze their distribution, so as to provide a reference for the normal detection and control of the flow of the vortex flowmeter. It is found that the turbulent kinetic energy and eddy viscosity are relatively small, and the flow velocity is distributed evenly in the flow passage of the vortex flowmeter, and the value of the flow velocity in each section of the flow passage has little difference, which is consistent with the stable operation of the vortex flowmeter in each working condition. The application of CFX calculation and simulation technology can improve effectively the rationality of vortex flowmeter design optimization, predict the performance of vortex flowmeter in advance, and improve the efficiency of design optimization.
