| Abstract: | 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 full-scale error of computation flow rate and the mean of it are 5.469 5% and 2.473 1% respectively. |
