On stability of a clamped-pinned pipe conveying fluid
In the past, stability of an undamped clamped-pinned pipe conveying fluid has been always considered numerically leading to controversial results. Païdoussis (2004) has shown that a numerical stability analysis of a clamped-pinned pipe requires exceptionally large number of vibration modes to obtain the correct dynamical behaviour. In this paper, analytical proof of stability of a clamped-pinne...
متن کاملAnalysis 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 کاملIn-Pipe Inspection Crawler Adaptable to the Pipe interior Diameter
One of the most important requirements of repairing and maintaining of pipelines is the ability to monitor and evaluate the pipe’s interior. In this paper, a novel apparatus to traverse pipes is introduced. The mechanism employs three independent rubber track units which are circumferentially spaced out 120 degree apart symmetrically. The apparatus employs an active mode to adapt to a wide rang...
متن کاملEfficient Approximation Algorithms for Point-set Diameter in Higher Dimensions
We study the problem of computing the diameter of a set of $n$ points in $d$-dimensional Euclidean space for a fixed dimension $d$, and propose a new $(1+varepsilon)$-approximation algorithm with $O(n+ 1/varepsilon^{d-1})$ time and $O(n)$ space, where $0 < varepsilonleqslant 1$. We also show that the proposed algorithm can be modified to a $(1+O(varepsilon))$-approximation algorithm with $O(n+...
متن کاملAn Experimental Correlation for Friction Factor in Horizontal Pipe with Trapezoidal Section Inner Longitudinal Slots for Conveying of Solids
In order to increase the efficiency of the conveyance of the granular solids, a new experimental set-up is designed. The test rig has longitudinal trapezoidal slots in its conveying pipes. Through experimentation, a correlation for friction factor in terms of solid mass flow rate, fluid flow rate and Froude number is presented. It is shown that the mixture friction factor for pipes with inn...
