We study the spectral problem associated with equation governing small transverse motions of a viscoelastic tube finite length conveying an ideal fluid. The boundary conditions considered are general form, accounting for combination elasticity and viscous damping acting on both slopes displacements ends tube. These include many standard as special cases such clamped, free, hinged, guided condit...

In this article, the dynamical behavior of a standing cantilever pipe conveying fluid is investigated with time − delay. By applying piezoelectric materials and considering delay voltage, motion equation built motion-limiting constraints elastic support. The discretized into ordinary differential equations by Galerkin me...

surface and small scale effects on free transverse vibration of a single-walled carbon nanotube (swcnt) fitted with y-junction at downstream end conveying viscose fluid is investigated in this article based on euler-bernoulli beam (ebb) model. nonlocal elasticity theory is employed to consider small scale effects due to its simplicity and efficiency. the energy method and hamilton’s principle a...

The dynamics of elastic cantilevered smart pipes conveying fluid with non-uniform flow velocity profiles is presented for optimal power generation. Navier-Stokes equations are used to model the incompressible in circular pipe, and profile modification factors formulated based on Reynolds number Darcy friction factor. coupled constitutive dynamic equations, including electrical circuit, laminar ...

We present a structure-conveying algebraic modelling language for mathematical programming. The proposed language extends AMPL with object-oriented features that allows the user to construct models from sub-models, and is implemented as a combination of preand post-processing phases for AMPL. Unlike traditional modelling languages, the new approach does not scramble the block structure of the p...

This study concerns a monitoring technique based on vibration measurements for identifying the presence of an acoustic source in fluid-filled pipe conveying turbulent flow. In such situation, source-induced vibrations can be smeared with flow-induced vibrations, which hinders detection. To increase signal-to-noise ratio (SNR), beamforming techniques applied to measured by array accelerometers m...
