| 摘 要： | 针对科氏流量计在测量含气-液两相的流体时,流量计随着气体含量的增加,测量稳定性逐步变差的问题,采用流固耦合有限元技术,对科氏流量计进行了模态分析和流固耦合振动分析。作为一个实例,使用该方法模拟气泡含量以及分布对测量稳定性的影响,在气泡含量1%左右时测量相对稳定,气泡含量大于5%时测量稳定性很快变差。 |

| Abstract: | In the measurement of gas-liquid two-phase fluid, the Coriolismass flowmeter (CMF) measurement stability of the flow meter gradually deteriorated with the gas content increases. A method based on the fluid-solid coupling finite element technique has been developed for the modal analysis and fluid-solid coupling vibration analysis of the gas-fluid two-phase flow in Coriolis flowmeter. As an example, this method is used to simulate the effect of bubble content and distribution on measurement stability. The variation law of measurement stability has been preliminary mastered, that the measurement is relatively stable with a bubble content of 1%, and over 5% the stability changes rapidly. |
