涡街流量计旋涡上举力系数的研究

Study of the Lift Force in Eddy Street Flowmeter

在涡街流量计中,频率感测元件是其核心部件,旋涡上举力的大小直接影响到感测元件的灵敏度。本文通过实验与研究给出了比较准确的举力系数,为感测元件的设计提供了依据。

The frequency sense element is a hardcore in the eddy street flowmeter. The lift force of vortices influences the sensitivity of the frequency sense element. Lift force coefficient of vortex in eddy street flowmeter is obtained by experiment and theory analysis. The results are important for design of the street flowmeter.
