On the performance of a Coriolis Mass Flowmeter (CMF): experimental measurement and FSI simulation

Abstract

Computational methods that make use of single one-way Fluid Structure Interaction (FSI) for modeling the Coriolis Mass Flowmeters' (CMFs) operations are prone to inaccuracies. These errors are due to their limitations in describing a fully coupled fluid structure interaction. The aim of this study is to produce a CFD model of a CMF that uses an iterative two-way coupling of fluid structure interaction to accurately study its performance. The computational findings are benchmarked against accurate experimental measurements of the U-shape CFM. The deviation between the computed results and experimental measurements remains about 0.1% which is deemed acceptable. This reduction of uncertainties is largely attributed to the capability of the model to describe the effects of tube vibrations on the meter's operation.

Comparative Analysis of Numerical and Analytical Methods for Modeling the «flow Tube - Liquid» System in Coriolis Flowmeters

“…Однако, не смотря на то, что одномерные модели довольно легко реализовать, они не способны отразить физическую картину явлений, протекающих в кориолисовых расходомерах. В то же время трехмерные численные модели [5,[26][27][28][29][30][31][32][33][34][35][36] позволяют корректно описывать процессы, проходящие в системе «расходомерная трубка -жидкость».…”
