海底管线柔性导流板的变形方程研究
Study on the Deformation Equation of Flexible Spoiler Attached on Top of the Submarine Pipeline
摘要
Abstract
Submarine pipeline is one of most important parts of the ocean oil field exploitation system, which can be damaged by the very complex ocean environment. To make the pipeline self-burying, this paper proposes to use flexible spoiler instead of rigid spoiler attached on the top of the pipeline, which can not only increase the scour depth and range, but also abate both turbulence intensity the rigid spoiler acts on the flow above the pipe and wake flow vortex so as to decrease vibration of the pipe. The quadratic curved surface equation of deformed flexible spoiler and deflection of free end formula are deduced on the basis of dynamical relation under the conditions of both interstice ratio is zero and is not zero. A series of experiments has been conducted under unidirectional current in which different material and length of flexible spoilers were installed on the top of the pipelinc and the deformation of flexible spoilers is measured. By comparing the maximum deflection of free end and deformation of curved surface calculated by formulas with the data measured from experiments, find the two values are very close to each other. Therefore the formulas can be used to calculate the deformation of flexible spoiler attached .on top of thc pipeline approximately.关键词
