Abstract
The paper is about the development of a fluid-dynamic model for simulating the
behaviour of a device for the production of electric energy based on an oscillating
water column (OWC).
First of all it has been developed a 3-D model of the device using a tool in order to create the
grid used for the simulation.
The code used for the fluid dynamic simulation is OpenFoam, in particular the solver
InterFoam suitable for two-phase isothermal flow characterized by immiscible and
incompressible fluids, it uses the VOF (Volume of Fluids) model.
The aim of this work is the optimization of the model from the computational point
of view, in particular it has been conducted a sensitivity analysis on the processor’s number and
on the time step of calculation.
In the first phase of the work were taken into account two forcing, approximated with a sinusoidal
profile, corresponding to two types of waves more realistic for the site in which it was made the
experimental apparatus.
Subsequently it has been developed an analysis of the boundary condition in order to
simulate in the best way the incident wave.
Obviously it is possible to investigate more in detail the model realized in order to
optimize the simulation and validate the model with more experimental data.
