Experimental study of the wave propagation and decay in a channel through a rigid ice-sheet

Wave resonances in a narrow gap between two barges using fully nonlinear numerical simulation

“…When gap resonance occurs, high wave motions in the gap could be excited and hence large drift forces may act on the vessels. Utilizing the linear wave theory, Molin [2] derived the formula for estimating the frequencies of resonant modes in a moonpool via solving an eigenvalue problem, which was extended to gap resonances by a modification into an open-ended moonpool in Molin et al [3]. Later on the resonant behavior of fluid in the gap has attracted much attention especially at the first mode or piston mode, where wave amplifications are more significant than at others.…”

A two-dimensional numerical and experimental study of resonant coupled ship and piston-mode motion

“…Molin et al [13] generalized the approximative threedimensional method of Molin [10] to study the gap resonances of a ship by a terminal by substituting the Neumann conditions at the longitudinal ends with Dirichlet conditions. Based on this, the same approach was taken by Eatock Taylor et al [14], where they compared their approximated theory with results from a linear diffraction code with promising results both in terms of estimation of natural frequencies as well as level of fluid response in the gap.…”

Modeling of fluid resonance in-between two floating structures in close proximity

“…As discussed by Newman and Sclavouns (1988) and Molin et al (2002), the problem of fluid resonance in-between two barges arranged side-by-side with a small gap can be treated as an open-ended moonpool. However, the proper boundary condition (the no-flow Neumann condition or the zero pressure Dirichlet condition) for the ended boundary still requires further discussion.…”

“…It has been noted by other researchers that this problem is closely related to resonant phenomenon of the moonpool, which was comprehensively investigated by Molin (2001) and Molin et al (2002). Other works which pertain to this problem are those of Miao et al (2000), Zhu et al (2005;2008), Saitoh et al (2006), Iwata et al (2007), Wang and Wu (2008), and Lu et al (2011a;2011b).…”
