Computational Investigation on the Float-Type Flowmeter in Three-Dimensional Turbulence Flow Field
Abstract
Based on the turbulence models and computational fluid dynamics (CFD), this paper presents a computational investigation on three-dimensional turbulence flow field of the float-type flowmeter. The forced floating element can be analyzed quantitatively from pressure field and the meter's flow rate from velocity field can be obtained. Meanwhile, this research is combined with an approach proposed by the authors, i.e. the error analysis method of the float-forced-balance-degree', which can realize a reliable estimate of the flow rate of the studied flowmeter. Simulation and experimental results show that the maximum full-scale error of flow rate is 3.4 %, and the full-scale mean error, 1.77 %. However, the corresponding errors using conventional design are 23.7 % and 8.9 % respectively.
