Analysis of the nonlinear axial vibrations of a cantilevered pipe conveying pulsating two-phase flow
The parametric resonance of the axial vibrations of a cantilever pipe conveying harmonically perturbed two-phase flow is investigated using the method of multiple scale perturbation. The nonlinear coupled and uncoupled planar dynamics of the pipe are examined for a scenario when the axial vibration is parametrically excited by the pulsating frequencies of the two phases conveyed by the pipe. Aw...
متن کاملFlow-Induced Vibration Analysis of Supported Pipes Conveying Pulsating Fluid Using Precise Integration Method
Dynamic analysis of supported pipes conveying pulsating fluid is investigated in Hamiltonian system using precise integration method PIM . First, symplectic canonical equations of supported pipes are deduced with state variable vectors composed of displacement and momentum. Then, PIM with linear interpolation formula is proposed to solve these equations. Finally, this approach’s precision is te...
متن کاملDesign and Evaluation of a Magnetorheological Damper Based Prosthetic Knee
In this work, a magnetorheological (MR) damper based above-knee prosthesis is design and evaluated based on its performance in swing phase and in stance phase. Initially, a dynamic system model for swing phase of a prosthetic leg incorporating a single-axis knee with ideal MR damper was built. The dynamic properties of the damper are represented with Bingham parametric model. From Bingham model...
متن کاملAnalysis of the Nusselt number in pulsating pipe flow
Much attention has been given to the possibility of enhancing the heat transfer rate by superimposing pulsation on a mean flow inside a confined passageway. Industrial applications can be found in Stifling engines and reciprocating cycles, to name a few. A perusal of the relevant literature reveals that pulsating flows in a pipe and the attendant heat transfer have been the subject of several a...
متن کاملPreliminary Study of Modelling Dynamic Properties of Magnetorheological Fluid Damper
u(t) c 1 2 k 3 m f c Abstract A preliminary study was conducted to investigate numerical models that can be used to simulate the dynamic behaviour of a damper based on magnetorheological (MR) materials. Several articles presenting the results of experimental testing and mathematical modelling have been published recently. The goal for this study was to implement a selected model into the finite...
