摘要
为深入研究金属管浮子流量计的工作机理,采用计算流体力学和流体力学中湍流模式理论,对金属管流量计流场进行了数值仿真研究,获得了低黏度流体介质中浮子受力及浮子在受力平衡下的流量.数值模拟与物理实验标定数据的对比表明,模拟计算的流量最大满度误差为5.469 5%,平均满度误差为2.473 1%,说明数值仿真模型能满足金属管浮子流量计设计的需要.
Based on computational fluid dynamics (CFD) and turbulence model, a numerical study of the turbulent flow field of the metal rotameter is conducted to investigate the mechanism of metal rotameter. The forces on the float and the flow rate that makes float under balance are obtained through the research on the low viscous flow field. Comparison between the simulation results and the data of physical experiment shows that the simulation model of metal rotameter is acceptable; the maximum of it are 5. 469 5% and 2. 473 1% respectively. full-scale error of computation flow rate and the mean
