“…More recently Binulal et al [16][17][18] directly coupled the fluid flow and tube oscillations into a single equation of motion to study the dynamics of CFM pipe conveying fluid. This method allows the determination of the influence of fluid flow on overall dynamics of the system including effects of added mass of the fluid, effect of pressure exerted on pipe's wall by the fluid and effect of centrifugal forces.…”

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.

“…With deeper understanding of the gyroscopic dynamics, the nonlinear properties of gyroscopic systems gradually became research focus, including the responses to external excitation and parametric resonance studied by perturbation method [4] and numerical method [5], and the mode interactions due to internal resonance [6]. Currently, great progress has been made towards exploration of various gyroscopic structures, involving the fluid-structure interaction systems [7,8], axially moving systems [9] and rotating bodies [10]. The threebody problems in celestial mechanics, a discrete gyroscopic system, are also concerned in nonlinear dynamic realm [11].…”

Nonlinear normal modes and a numerical iterative approach are applied to study the parametric vibrations of pipes conveying pulsating fluid as an example of gyroscopic continua. The nonlinear non-autonomous governing equations are transformed into a set of pseudo-autonomous ones by employing the harmonic balance method. The nonlinear normal modes are constructed by the invariant manifold method on the state space and a numerical iterative approach is adopted to obtain numerical solutions, in which two types of initial conditions for the modal coefficients are employed. The results show that both initial conditions can lead to fast convergence. The frequency-amplitude responses with some modal motions in phase space are obtained by the present iterative method. Quadrature phase difference and traveling waves are found in the time-domain complex modal analysis.

The authors made a computational study of forced oscillations of a straight pipe with a flowing fluid under an external driving force using beam model. The phase shift of the oscillations of two points of the tube was obtained considering the noncentral application of the driving force and the asymmetry of the location of the sensors. The approach proposed was aimed at solving the problem of forced oscillations of a beam with a flowing fluid. It enables to use the beam modal shapes with a standing fluid found by the finite element method. The equation of transverse vibrations of a beam with a flowing fluid with an allowance for internal friction on the tube material was proposed. The allowance for friction on the tube material made it possible to solve the problem of forced resonance oscillations of a beam with a flowing fluid in a nonstationary formulation. The results obtained on the beam model were verified using a three-dimensional finite element model of a straight pipe with the flowing fluid. The results obtained can be used in prototyping Coriolis flowmeters.
