Abstract The article presents an investigation of the stabilization a cantilever pipe discharging fluid using electromagnetic actuators transformer type. With flow velocity reaching critical value, straight equilibrium position becomes unstable, and self-excited lateral vibrations arise. Supplying voltage to yields two opposite effects. First, each attracts pipe, thus introduces effect negative...

Abstract Creatures with longer bodies in nature like snakes and eels moving water commonly generate a large swaying of their or tails, the purpose producing significant frictions collisions between body fluid to provide power consecutive forward force. This can be idealized by considering oscillations soft beam immersed when waves vibration travel down at constant speed. The present study emplo...

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 ...

This paper investigates numerically the hydraulic conveying of solids through a 90$^{\circ}$ elbow that changes flow direction from horizontal to vertical, in very-narrow case where ratio pipe particle diameters is less than 5. We performed resolved CFD-DEM (computational fluid dynamics - discrete element method) computations, which we made use IB (immersed boundary) method open-source code CFD...

In this article, the vibrational behavior of a spinning cylindrical thick shell carrying spring- mass systems and conveying viscos fluid flow under various temperature distributions is investigated. This structure rotates about axial direction and the formulations include the coriolis and centrifugal effects. In addition, this system is conveying viscous fluid, and the related force is calculat...

Structures dynamic characteristics and their responses can change due to variations in system parameters. With modal of the structures, be identified. Mode shape remains vital analysis structures. It utilized failure analysis, interaction between structures supports circumvent abrupt failure. Conversely, unlike empty pipes, mode shapes for pipes conveying fluid are tough obtain intricacy eigenv...
