Numerical and Empirical Investigation of Flow Separation Phenomenon around Semi-buried Pipelines due to Steady Currents
In this paper, in order to understand the flow-pipe interaction more clearly, the variations on flow pattern around semi-buried pipelines due to steady current have physically and numerically been investigated. In physical modeling section, the experiments have been carried out in a flume with 10 meter length, 0.3 meter width and 0.5 meter depth using a P.V.C pipe with 6.35 cm in diameter (for ...
متن کاملControl of Scour around the Submarine Pipelines in the River Bed
This paper presents, a set of experiments was conducted in a Plexiglas flume setup to investigate the simultaneous use of pipe and blade in the scour control around a submerged pipe. A vertical cylindrical pipe with and without a blade placed below it was selected for the experiments. The experiments were carried out in two different sates: with blade and without blade the pipe. Moreover, they ...
متن کاملNumerical simulation of flood wave propagation due to failure of dam watersheds in fluent model
By numerical simulation of the phenomenon of failure of dams and the flow of their flow, it is possible to design more precisely the structures and their location. The purpose of this study was to investigate the wave propagation phenomenon due to the failure of the rocky mortar-watering dam in the Marivan sub-basin of Zarivar in two-dimensional and three-dimensional models using the Fluent mod...
متن کاملWave front dispersion due to fluid-structure interaction in long liquid-filled pipelines
Half a century ago Richard Skalak (1923-1997) (Ref 1) published a paper with the title "An extension of the theory of water hammer" (Refs 2, 3, 4), which has been the basis of much subsequent work on hydraulic transients with fluid-structure interaction. The paper considers the propagation of pressure waves in liquid-filled pipes and the coupled radial/axial response of the pipe walls. In a tri...
متن کاملRefinement to the Existing Analytical Methods of Analysis of Buried Pipelines due to Strike-Slip Faulting
Analytical methods presented to analyze the buried steel pipelines at strike-slip fault crossing use the Euler-Bernoulli beam theory. The cross-section of a buried pipe that is completely surrounded by soil cannot rotate freely and would not be remained perpendicular to the bending line after deformation. So it would be better to take into consideration a rotation between the cross-section and ...
