NUMERICAL STUDY ON THE EFFECT OF LOW REYNOLDS NUMBER FLOWS IN STRAIGHT TUBE CORIOLIS FLOWMETERS

Rongmo Luo, Jian Wu, Steven Wan

Abstract

A numerical model has been developed to simulate the single straight tube Coriolis mass flowmeters (CMFs), to study the vibration mode shape of the sensor tube for mass flow rate measurement. In this model, a finite volume (FV) code for fluid flow analysis and a finite element (FE) code for structural analysis are coupled based on the theories of fluid-structure interaction. The effect of the low Reynolds number on the sensitivity of CMF has been studied in details, and the simulation results can gain a deeper understanding of the error behaviour of CMFs under high viscous flow.
