Abstract
This paper presents the study of the axisymmetric velocity profile effects in the shell-type Coriolis flowmeter with second circumferential mode, which exploits the results of CFD simulations. Simulations were carried out for viscous fluid flow in the vibrating measuring tube, whose mode shape remained fixed during the transient simulation process. We observed time responses of the integral anti-symmetric fluid forces acting on the inner wall of the measuring tube. Their magnitudes and their relative variations with the mass flowrate of the fluid were used for the integral estimation of the velocity-profile effect. In addition to that, the results are compared with the weight-vector estimations of the velocity-profile effect and are evaluated for two different turbulent models. Simulations were performed for different Reynolds numbers and two dimensions of the measuring tube.
