Experimental Measurements And Numerical Studies On The Motion Response Of Floating Oil Booms And Containment Failure Under Waves And Currents

Oil spill will cause extensive environment damage to the marine ecosystem.Oil boom is a simple yet effective tool that can effectively prevent spread of oil spill,reduce the area of oil spill,and aid in the recovery of oil.Due to the complexity of the waves and currents,it is essential to estimate motion response of the boom and mechanism of containing oil in waves and currents when choosing the type of the boom according to different sea situation.Based on the physical experiment and numerical simulation platform of FLOW-3D,the motion response of floating oil booms and mechanism of containing oil in waves and currents are explored.In this study,the motion response of boom with different features to different waves and currents will be investigated through flume tests and the effect of waves and currents on the minimum effective boom freeboard and drafts will be analyzed.In addition,the heave and rotation of oil boom in the waves and currents will be analyzed.In the view of the medium viscosity oil,the influences of different features of oil boom and different waves and currents on the entrainment failure and the drainage failure are explored.Also,the effect of the flow velocity on the thickness of the oil is studied.On the basis of the previous researches of two-dimensional numerical wave flume by the FLOW-3D,a two-dimensional numerical wave flume,the same as the experiment model,is established;and the validity of the wave-current flume is verified.Based on this two-dimensional numerical wave flume,the motion response of the rigid oil boom and the mechanism of containing oil are simulated,and the reliability of the numerical simulation is verified by comparing with the experimental results.
