Description
Technical field
What the present invention relates to is a kind of test unit of field of ocean engineering, and specifically, what relate to is that a kind of in-situ velocity increases inclination angle ladder incoming flow vortex-induced vibration of marine riser test unit.
Background technology
Standpipe is one of important equipment of deep-sea oil gas exploitation.Along with oil-gas mining marches to deep-sea, the operating water depth of standpipe is increasing, and in deepwater regions, wave and sea ship motion weaken gradually to the damage that standpipe causes, but ocean current becomes the principal element causing standpipe to damage.The effect depth of water scope of ocean current is very large, when ocean current is through marine riser, the vortex shedding that generation replaces by standpipe trailing edge, when vortex shedding frequency is close with the standpipe natural frequency of vibration, the vibration of standpipe will force vortex shedding frequency to be fixed near the standpipe natural frequency of vibration, bring out vortex-induced vibration.Vortex-induced vibration is the main cause causing standpipe generation fatigure failure.
At present, the research of academia to vortex-induced vibration more concerns axis of no-feathering is to the situation vertical with incoming flow, and in actual oceanographic engineering, vertical tube structure is axially also not exclusively vertical with incoming flow, there is certain angle of inclination.For this complicated situation, have scholar to propose the uncorrelated principle of inclination flexible cylindrical vortex-induced vibration, namely suppose inclination flexible cylindrical vortex-induced vibration and speed of incoming flow axis of no-feathering to the vertical cylinder situation equivalence that causes of vertical direction projection components.But still there is dispute so far in the correctness of uncorrelated principle.
The most reliable and the most effective means of research vortex-induced vibration of marine riser phenomenon are model tests.By model test, than more comprehensively observing the impact that vortex-induced vibration phenomenon, principal character and inlet flow conditions produce vortex-induced vibration, the precision that test findings comparatively reliably comes effect theory and numerical model can be obtained.Accumulate experience for engineering is actual.At the oceanographic engineering environment of reality, not only axially there is certain inclination angle with incoming flow vertical direction in standpipe, be not simultaneously unalterable from sea level to the flow velocity cross section within the scope of the entire depth of seabed, the deepwater regions in the such as Gulfian or South China Sea, in the scope on 300 meters, general top layer, mean flow rate is 4 to 5 times of the 300-800 rice depth of water, be more than 20 times of below 800 meters of depth of waters, the flow velocity that there is local increases region suddenly.Can find, the incoming flow within the scope of entire depth is that in-situ velocity increases inclination angle ladder incoming flow.
Through finding existing technical literature retrieval, considerably less for in-situ velocity increase inclination angle ladder incoming flow vortex-induced vibration of marine riser experimental study both at home and abroad.The stepped incoming flow riser vortex excited vibration test be directed under aclinal plumbness has to be carried out.Paper " Laboratorymeasurementsofvortex-inducedvibrationsofaverti caltensionriserinasteppedcurrent " (the vertical single tensioned risers vortex-induced vibration test observation of stepped inlet flow conditions) in 21st phase " JournalofFluidsandStructures " magazine in 2005, devises the test unit of a set of exquisiteness.The towing basin water surface is holded up a bucket, bung is below the water surface, due to atmospheric reason, just the water column of height in 10 meters can be had after being evacuated in bucket, standpipe is long 13.12 meters, and upper end is fixed on the upper of bucket, and at the bottom of lower end and pond, annex supports, bucket is fixed on trailer, produces stepped incoming flow test condition after starting trailer.But this device cannot realize the stepped inlet flow conditions in in-situ velocity increase inclination angle.
Through finding existing technical literature investigation, increase the stepped vortex-induced vibration of marine riser experimental study in inclination angle for in-situ velocity both at home and abroad and also do not carry out, main cause lacks necessary test unit.How to realize inclination angle inlet flow conditions, how to realize in-situ velocity and increase, and how to realize stepped inlet flow conditions etc. be need the technical barrier overcome badly.
