More Information
    Corresponding author: Odd Magnus Faltinsen was born in 1944 in Stavanger, Norway, and obtained a cand. real. in applied mathematics at the University of Bergen in 1968 and a PhD in Naval Architecture and Marine Engineering in 1971 at the University of Michigan. He has worked on broad aspects of hydrodynamics of displacement ships, high-speed craft, offshore structures, and fish farms. He has been professor of Marine Hydrodynamics from 1976 at NTNU and educated 59 PhDs. He is a honorary professor at Harbin Engineering University, Academic Master at Dalian University of Technology, and has been visiting professor three 1-year periods at Massachusetts Institute of Technology (MIT), US. Faltinsen is the author of the three textbooks Sealoads on Ships and Offshore Structures, Hydrodynamics of High-Speed Marine Vehicles, Sloshing (co-authored with A. N. Timokha). Cambridge University Press has published them all. All of them have been translated to Chinese. He has authored about 450 publications in scientific journals, conferences and books, and given about 50 keynotes and honors lectures. Faltinsen gave the 15th GeorgWeinblum Lecture, 1992-1993 and Third Annual Honors Lecture, The Offshore Technology Research Centre, College Station and Austin, Texas; 1993. He received the Fridtjof Nansen's award for outstanding research in science and medicine in 2011. The 26th International Workshop on Water Waves and Floating Bodies held in Athens on April 1720, 2011 was dedicated to Professor Odd M. Faltinsen for his "lifetime scientific achievements". The "Professor Odd Faltinsen Honoring Symposium on Marine Hydrodynamics" was arranged at Conference on Ocean Offshore & Arctic Engineering (OMAE) 2013, Nantes, France in June 9-14, 2013. He received the Ocean, Offshore and Arctic Engineering (OOAE) Division-American Society of Mechanical Engineers (ASME) Lifetime Achievement Award in "grateful recognition of significant lifetime contributions to marine and offshore hydrodynamics" in June 2013 and the Sobena International Award in 2014. Faltinsen is elected member of Norwegian Academy for Technical Sciences, Norwegian Academy of Science and Letters, The Royal Norwegian Society of Sciences and Letters, corresponding member of Croatian Academy of Sciences and Arts, foreign member of the National Academy of Engineering, USA and the Chinese Academy of Engineering.

  • 摘要: 本文列举了诸多工程领域中的液体共振运动现象,详细探讨了船舱中伴有剧烈流动的晃荡问题.描述了基于理论分析的非线性多模态方法,该方法便于波动稳定性分区、多分支解和物理稳定性的研究.强调了方形舱、垂向圆柱舱以及球形舱内伴有旋转和混沌(不规则波动)的三维流动的重要性.晃荡引起的砰击涉及到各种各样的内流条件,这些条件随液体深度与舱体长度之比而变化.针对棱柱状LNG舱,讨论了许多与流体力学和热力学参数、影响砰击载荷效应的水弹性以及模型实验缩尺比的物理现象.

     

  • Figure  1.  Examples of typical periodic (steady-state) free-surface motions for shallow (a), intermediate (b), nearly critical (c), and finite (d) liquid depth conditions for forced horizontal oscillations with period T near the highest natural sloshing period T1 of two-dimensional flow in a rectangular tank. Shallow liquid conditions (a) are for h/l=0.125, h/l=0.125 , T/T1=1. The forcing amplitude to tank breadth ratio is 0.1. Nearly-critical depth conditions (c) are for h/l = 0.35, T/T1 = 0.787

    Figure  2.  Experimental and theoretical stability boundaries T,S, and P for non-dimensional filling depth h/R0=0.6 and different longitudinal forcing amplitudes ε=η1a/R0 versus non-dimensional forcing frequency σ/σ11. Empty (stable) and solid (unstable) symbols are experimental bounds taken from Sumner and Stofan (1963) . The symbols related to S are covered by a shadow area. Theoretical stability boundaries are marked by the solid lines T, S, and P (Faltinsen & Timokha, 2013)

    Figure  3.  Dimensionless steady-state wave elevation near the vertical wall =(fmax - fmin)/h (as proposed by Chester and Bones(1968) ) versus the excitation frequency. Rectangular tank with water depth-to-tank breadth ratio h/l = 0.08333 and 2D flow. Horizontal harmonic excitations. The calculated data are for fresh water with kinematic viscosity coefficient ν=1.1×10−6m2⋅s−1. ◊ = experiments by Chester and Bones(1968) , dashed line = Boussinesq-type multimodal theory and solid line = theory by Chester (1968) . (a) η2a/l=0.001254, (b) η2a/l = 0.002583

    Figure  4.  Three different scenarios of impact against the tank roof considered by Rognebakke and Faltinsen (2005) : (a) high-curvature free-surface impact with a high velocity jet; (b) flat impact; (c) impact with oscillating gas cavity
