Dear FOAMers,
All started one year ago... The challenge was to organize a workshop according to the standardsof the previous editions. Just a few weeks were enough to realize that, similarly to the spirit of theOpenFOAM R©community, these type of organizations cannot be undertaken by just one person. It was thebeginning of the sweat4Foam, a group that was much more than a set of event organizers.
At the beginning it started with a slow convergence and it seemed to be very stable, however closer to theOFW11 the convergence rate increased but with visible instabilities.
We gave our best and finally reached convergence. Now its the time for V&V.
We hope you find useful the time spent at the OFW11 and we also hope that you enjoy (and return in thefuture to) Guimaraes.
Finally, it is important to mention that this workshop would not be possible without the generous supportof the OFW11 sponsors.
Miguel Nobrega,
In representation of the sweat4Foam team.

1. INTRODUCTION
Wave energy from ocean waves is captured by Wave Energy Converters (WECs) and converted into electrical power.
In this study, WECs of the floating point absorber (FPA) type are selected. Their geometry is represented by a
cylindrical buoy with a spherical end. The focus of this study is limited to a free decay test of a single WEC.
2. NUMERICAL MODELLING
CFD-modelling is performed to study the behaviour of a single WEC in a
wave field using OpenFOAM. Simulations of the two-phase flow field are
performed by solving the incompressible RANS-equations. Wave generation
and absorption at the boundaries of the numerical wave tank are
implemented in the IHFOAM toolbox. The CFD-fluid solver is coupled to a
motion solver in order to simulate rigid body motions. Only the governing
motion of the WEC’s behaviour is considered, the heave motion.
Important parameters of the WEC, such as the damping ratio ζd, natural
angular frequency ωn and damped angular frequency ωd, are obtained from a
free decay test. During such a free decay test, the body is placed out of
equilibrium with an initial displacement. A damped oscillatory motion is
started after releasing the WEC until all the forces acting on that WEC are in
equilibrium. In order to validate the numerical model, experiments in a wave
flume were conducted to measure the WEC’s heave motion. Therefore, a
steel shaft was installed through a vertical shaft bearing over the whole
height of the WEC (see Figure 1a). Because of the complexity of meshing the shaft bearing inside the WEC, another
methodology is formulated to obtain a grid around the WEC without that vertical shaft (see Figure 1b).
Firstly, the shaft inside the physical WEC reduces the water-plane area Aw and changes the natural frequency ωn.
Moreover, the natural frequency is dependent on the mass m and added mass ma. Therefore a WEC without shaft but
with a modified mass mnum is implemented in OpenFOAM. This is done to obtain the same natural frequency as the
physical WEC, assuming that the damping ratio ζd and added mass ma are identical in both experimental and numerical
models, see eq. (1). The modified-mass method can be derived starting from the expression in eq. (1). Subsequently, the
damped frequency ωd in both numerical and experimental models are rewritten by using eq. (2) and (3). Finally, this
procedure returns eq. (4) which calculates the modified mass mnum needed in the numerical model to satisfy eq. (1).

Secondly, there is a motion of a viscous fluid, water, in the underwater space between the steel shaft and the shaft
bearing. This flow can be simplified as a Couette flow between two parallel plates of which one is moving relative to
the other. This Couette flow is responsible for a viscous force acting parallel to the motion of the moving plate (shaft
bearing inside the WEC). This force is dependent on the viscosity of water, the space between the plates and the
velocity. However, a simplified model is assumed by only including the velocity v explicitly using a linear damper
(F = -c·v) in which c is the damping coefficient. As expressed in eq. (5), the WEC’s damping ratio ζd is equal to the

WEC [1]. (b) 3D grid around the WEC.

ratio of the damping coefficient bd and the critical damping coefficient bc. The target damping coefficient bd,target is
calculated by eq. (5) using the experimental damping ratio and the WEC’s modified mass. Subsequently, the numerical
damping coefficient bd,num is determined following the same eq. (5) but now using the numerical damping ratio. This
numerical damping ratio is obtained from a CFD simulation without linear damper, so the Couette flow is neglected.
Thereafter, the difference between both damping coefficients is used as the damping coefficient c of the linear damper
inside the motion solver to account for the Couette flow, see eq. (6).

3. RESULTS
The numerical model described in the previous paragraph is used to simulate a free decay test using the structured grid
shown in Figure 1b consisting of solely hexahedral cells. Only the lowest and highest row of cells are distorted to
prevent undesirable mesh deformation around the air-water-interface. Figure 2 presents the WEC’s heave motion with
respect to its equilibrium position. The continuous blue line represents the numerical result while the dashed red line
shows the experimental data from the wave flume. The dashed-dotted black line depicts the analytical envelope [1]. In
general, the figure proves that this numerical result is extremely close to the experimental decaying motion. After 13 s,
some small discrepancies in the phase of the signal are observed between CFD and the experiment due to the different
absorption methodology between IHFOAM and the physical wave flume. Moreover, the motion of the WEC generates
radiated waves, which are shown at five locations (Figure 3a) for both numerical and experimental results in Figure 3b.
Although these small-amplitude waves (< 1 cm), both results are very similar in the first 10 seconds of the signals.
Thereafter, some deviations between both results are observed. Numerical results obtained from simulations using a
smaller time step or a denser grid are converging towards a time- and grid-independent solution. All these observations
show that OpenFOAM/IHFOAM is a robust and suitable toolbox to research wave-structure interaction.
Figure 2: The WEC’s vertical position during a free decay obtained with CFD (continuous blue line, Δt = 0.001 s, Δz = 0.02 m)
compared to the experimental decaying motion (dashed red line) and the analytical envelope (dashed-dotted black line).
Figure 3: (a) Plan view of the five wave gauges inside the numerical wave flume. The WEC’s centre (x = 0 m ; y = 0 m) is
located at the upper left corner while the absorbing wave boundary condition is located at the right side of the domain (x =
4.95 m). (b) The radiated wave field represented by the surface elevation ηi in function of time t (Δt = 0.001 s, Δz = 0.02 m).
