“…extended this method to non-wall-sided cylinder cases based on the 3-D semi-unstructured mesh. Wang & Wu (2010) made further simulations for interactions between waves and vertical cylinder arrays in a numerical tank (see Fig.5.7). The wave maker undergoes motion in x-direction with cos x a t ω = − .…”

“…considered a vertical cylinder with flare, which was a further development of the 2-D work on the non-wall sided body (Wang & Wu 2004). An array of cylinders in a wave tank was also investigated by based on the second order theory and by Wang and Wu (2010) based on the fully nonlinear theory. Ma and Yan (2006) also undertook simulations for nonlinear water waves.…”

We review recent advances in the finite element method (FEM) simulations of interactions between waves and structures. Our focus is on the potential theory with the fully nonlinear or second-order boundary condition. The present paper has six sections. A review of previous work on interactions between waves and ocean structures is presented in Section one. Section two gives the mathematical formulation. In Section three, the finite element discretization, mesh generation and the finite element linear system solution methods are described. Section four presents numerical methods including time marching schemes, computation of velocity, remeshing and smoothing techniques and numerical radiation conditions. The application of the FEM to the wave-structure interactions are presented in Section five followed by the concluding remarks in Section six.

“…For example, Ma et al (2001aMa et al ( , 2001b) developed a fully nonlinear finite element model for simulating the interactions between fixed vertical cylinders and steep waves [8,9]. Wang and Wu (2010) studied the nonlinear interactions between water waves and vertical cylinder arrays in a finite-element based numerical tank [14]. However, although considerable numerical models have been applied to study current or wave interacting with a cylinder, it is very rare that a numerical model has the capability of simultaneously predicting a current interacting with a cylinder and the interaction between wave and a cylinder.…”

This paper presents numerical simulations of a circular cylinder under the action of current or wave only. The model solves the three-dimensional (3D) Reynolds-averaged Navier-Stokes equations using an explicit projection method. The 3D grid system is made of lots of prisms, which are built from a two-dimensional horizontal triangular grid by adding a number of horizontal layers. A non-linear k-ε model, which can take into account the anisotropy of turbulence is incorporated as a turbulence model. Two test cases including the current flows around and regular waves interact with a circular cylinder are used to demonstrate the capability of the model. The model gives reasonable results in comparison with available experimental data.

“…It was found that at relatively high frequencies, the enhancement of the second-order component in the wave run-up was much more general than on the forces. Wang and Wu (2010) developed a fully nonlinear numerical wave tank to simulate three-dimensional waves and wave-structure interactions by the finite element method. The effect of the tank wall on waves and forces was investigated, and the nonlinear features of waves and 4 forces were also discussed.…”

. (2015). Multi-directional random wave interaction with an array of cylinders. Ocean Engineering, 110, 62-77. DOI: 10.1016/j.oceaneng.2015 ABSTRACTBased on the linear theory of wave interaction with an array of circular bottom-mounted vertical cylinders, systematic calculations are made to investigate the effects of the wave directionality on wave loads in short-crested seas. The multi-directional waves are specified using a discrete form of the Mitsuyasu-type spreading function. The time series of multi-directional wave loads, including both the wave run-up and the wave force, can be simulated. The effect of wave directionality on the wave run-up and wave loading on the cylinders is investigated. For multi-directional random waves, as the distribution of wave spreading becomes wider, the wave run-up at some points around the cylinders is found to increase. This suggests that multi-directional wave run-up tends to be larger than unidirectional wave run-up. In addition, the wave directionality has a significant influence on the transverse force. The biggest transverse force is found to occur on the rear cylinder rather than the front one. This is quite different from the results in unidirectional waves and should be paid much more attention in the design of offshore structures. At last, the possibility of the near-trapping under the multi-directional random waves is investigated. It is found that the near-trapping also occurs for multi-directional wave conditions.
