【期刊论文】Noncoaxial vibration of fluid-filled multi-walled carbon nanotubes

This paper is concerned with the free vibration of the fluid-filled multi-walled carbon nanotubes (MWCNTs) with simply supported ends. Based on simplified Donnell’s cylindrical shell model and potential flow theory, the effect of internal fluid on the coupling vibration of the MWCNTs-fluid system is discussed in detail. The results show that the resonant frequencies are decreased due to the effect of the fluid, and the fluid has only a little influence on the associated amplitude ratio in MWCNTs corresponding to the natural resonant frequency (frequency of the innermost tube), while plays a significant role in the associated amplitude ratios corresponding to the intertube resonant frequency. For the natural resonant frequency, the vibration mode is coaxial. However, for the intertube resonant frequency, the system shows complex noncoaxial vibration, which plays a critical role in electronic and transport properties of carbon nanotubes (CNTs).

An analytically nonlocal Euler-Bernoulli beam model for the wave propagation in fluid-filled single-walled carbon nanotube (SWCNT) is established. The governing equations with the nonlocal effects are derived on the variational principle, and used in the wave propagation analysis of the SWCNT beam. Compared with the partially nonlocal Euler-Bernoulli beam models used previously, the analytically nonlocal model presented in the present study predicts well the effects of the stiffness enhancement and the wave damping at the high wavenumber or the strong nonlocal effects area for the fluid-filled SWCNT beam. Though the analytically model is less sensitive than the partially nonlocal model when the moving velocity of the internal fluid is high enough, it simulates more of the high-order nonlocal effecting information than the partially nonlocal model does in many cases.

This paper is concerned with the characteristics of wave propagation in double-walled carbon nanotubes (DWCNTs). The DWCNTs is simulated with a Timoshenko beam model based on the nonlocal continuum elasticity theory, referred to as an analytically nonlocal Timoshenko-beam (ANT) model. The governing equations of the DWCNTs beam consist of a set of four equations that are derived from the variational principle of the beam with high-order boundary conditions at the both ends, in which the effects of the nano-scale nonlocality and the van der Waals interaction between inner and outer tubes are inclusive. The characteristics of the wave propagation in the DWCNTs beam were analyzed with the new ANT model proposed and the comparisons with the partially nonlocal Timoshenko-beam (PNT) models in publication were made in details. The results show that the nonlocal effects of the ANT model proposed in the present study on the wave propagations are more significant because it is in stronger stiffness enhancement to the DWCNTs beam.

A numerical simulation scheme of 3D incompressible viscous fluid in a box flow passage is developed to solve Navier-Stokes (N–S) equations by firstly taking fluid-structure interaction (FSI) into account.This numerical scheme with FSI is based on the polynomial differential quadrature (PDQ) approximation technique,in which motions of both the fluid and the solid boundary structures are well described.The flow passage investigated consists of four rectangular plates,of which two are rigid,while another two are elastic. In the simulation the elastic plates are allowed to vibrate subjected to excitation of the time-dependent dynamical pressure induced by the unsteady flow in the passage.Meanwhile,the vibrating plates change the flow pattern by producing many transient sources and sinks on the plates.The effects of FSI on the flow are evaluated by running numerical examples with the incoming flow’s Reynolds numbers of 3000,7000 and 10,000,respectively.Numerical computations show that FSI has significant influence on both the velocity and pressure fields,and the DQ method developed here is effective for modelling 3D incompressible viscous fluid with FSI.

A set of nonlinear partial differential equations was used to describe the motions of an internal flowing system,with the consideration of transient fluid structure interaction (FSI).The stabitity characteristics of the system were analyzed on the basis of the nonlinear FSI-equation model.The results show that the stability of the nonlinear FSI system become very complicated because of the influence of strongly couplied interaction between flowing liquid and vibrating pipe.The flowing velocity,pressure,the piping stiffness,and constrained conditions,etc.play a very important role in developing procedure of the system stabilization.In an analysis example given in this paper,for example,when the flowing pressure is comparatively small,the system exhibits flutter instability,and when the flowng pressure is increases to a specified value,a subcritical divergence and a supercritical flutter bifurcation take successively place in the same velocity range.

Pressure wave propagation along a pipe atta-ched with an active pressure-controlling system at an end was described by an unsteady state-changing motion of the pres-sure wave fronts.in order to study the interaction among sue-cessive waves caused by successive controlling spillovers with the consideration of liquid compressibility due to high head.A model for water hammer propagation was established by using the continuity,momentum,and energy equations.The influ-ence of the wave interactions on the pressure suppression was analyzed.Testing verifications were conducted with a 2575m length and 776m head penstock in hydro-power station.The computed results are in good agrement with the tested ones.

In this paper,an analytical solution for the four-equation model describing fluid-structure interaction in liquid-filled pipes subjected to impact-induced water hammer is presented.The analytical solution is derived for the case of both Poisson coupling and junction coupling.The results obtained from the analytical solution are in good agreement with experimental measurements and with numerical solutions determined by the method of characteristics.Taking advantage of the analytical solution, some features of coupled wave propagation are presented and discussed.

Results are described from a combined numerical and laboratory model study of the turbulent flow in a true 3D blade passage of a Francis hydro-turbine.The large eddy simulation (LES) is applied to investigate the intrinsic features and the spatial and temporal variations of the flow structures in the blade passage with strong wakes in inflow sweeping and the turbulence-induced blade vibration.The flow passes through the vibrating boundaries.Therefore,the system under consideration is in a dynamic fluid-structure interaction (FSI).In the simulation, one-coefficient dynamic sub-grid scale (SGS) model is incorporated in LES with Reynolds number 148400 to better describe the energy exchange mechanism between large and small scales under the influences of strong geometrical curvature and vibrating boundaries.The governing equation of the blade vibration with FSI has been established by generalized variational principle combining the fluid and the structure.The vibration analysis is carried out by using Wilson-θ method.Separate iteration schemes are applied to solve the flow and the vibration in turn.The pressures on the wall sides of the blade and its vibrating accelerations are simultaneously measured.The numerical results show that the temporal and spatial distributions of turbulence in the 3D blade passage are significantly influenced by the curvature of blade configuration,the blade vibration, and the distorted wakes generated by flow passing through guide vanes.The influences of the vibration on the near-wall flow structures are quite remarkable.The simulated results are favourably compared with the measurements.

A constitutive relationship for high strength concrete in triaxial monotonic and cyclic compressions is developed based on the continuum damage mechanics.The bounding surface concept is employed in the formulation of the theoretical model.An experimental program was undertaken in order to establish databases for high strength concrete under triaxial monotonic and cyclic compressions.The stress-strain responses of high strength concrete subjected to triaxial monotonic and cyclic compressions were acquired through an experimental program. Comparison of the stress strain results indicates good agreement between the theoretical model and the experimental data.

This paper is concerned with the vibration analysis of a liquid-filled pipe system,which extends the frequency domain analysis of the fluid–structure interaction from single pipe to a pipe system with multi-pipe sections using transfer matrix method.Taking into account all the three major coupling mechanisms,namely the friction coupling,Poisson coupling and junction coupling,the proposed method can be used to analyze the free vibration and the forced vibration of a pipe system with multi-pipe sections subjected to various kinds of external excitations.The transform matrix,impedance matrix and frequency equation in frequency domain are also presented and discussed.Numerical examples are presented to illustrate the application of the proposed method,which shows how the natural frequencies and mode shapes change with the radius and materials of the pipe system.
