The effect of flow conditions on the sensitivity of the Coriolis flowmeter

Coupled finite-volume/finite-element modelling of the straight-tube Coriolis flowmeter

“…As expected that model performs better than the Euler beam and one-dimensional flow model and its results (for the considered slender tube configuration) deviate from those of the proposed numerical model of the same order of magnitude as those of the Flu¨gge shell and potential flow model. On the basis of the results presented herein and the study of Bobovnik et al (2004), where it was established that the actual fluid forces are in very good agreement with the onedimensional fluid flow assumption for the slender-type tube configuration, we can claim that significant differences between the models do not lie in the different treatment of the fluid flow, but originate from different approaches used in modelling of the structural domain.…”

Estimation of velocity profile effects in the shell-type Coriolis flowmeter using CFD simulations

“…The results in both cases predict relatively large sensitivity losses at lower mass flow rates, especially in the region of low Reynolds numbers, where a sensitivity decrease of up to 15% with respect to the uniform velocity profile is estimated. The estimated inlet velocity effect in shell-type Coriolis flowmeters seems to be much more important than in the case of beam-type Coriolis flowmeters, for which the sensitivity decrease was about a few tenths of a per cent, predicted in the turbulent flow region [1,2].…”

“…[1], where the influences of the inlet profiles on the characteristics of the beam-type configuration were investigated using CFD (computational fluid dynamics) simulations of the fluid flow in the vibrating measuring tube. In contrast to the beam-type meter with a first lateral mode, a straight tube shell-type meter with one axial and two circumferential waves in its mode shape is discussed in this paper.…”

Numerical analysis of installation effects in Coriolis flowmeters: Single and twin tube configurations

“…Our research group has already studied the installation effects in the single straight-tube Coriolis flowmeters analytically using the weight vector theory [5] as well as numerically [6,7]. The latest paper [7] employed a fully coupled three-dimensional numerical model that accounts for the fluid-solid interaction in the measuring tubes of the flowmeters.…”
