Abstract
The Wavesax device has been conceived to be installed in ports and harbours, in
the Mediterranean sea. Therefore, two aspects are quite important: flexibility of the device to
fit in different structural configurations and replication in a large number of units.
Preliminary numerical modelling of the fixed component of the device has been performed using
Computational Fluid Dynamics analysis (RANS-CFD model) and considering four regular wave
conditions typical of the Mediterranean sea.
Main issues to be considered in the first stage scale modelling analysis are the effective
functionality of the device conception (scale 1:20), the optimization of the design and position of
the device in terms of generated velocity gradients in the working section where the turbine blades
are installed. The main parameters to be investigated, both with numerical modelling and ocean wave
basin tests, are the pressure field in different sections of the device, water levels for
different wave conditions and device sinking.
Following the scale model test, the numerical model was calibrated and validated. The
paper presents the results of the numerical simulations related to different configurations of
the device, under typical Mediterranean wave climates.
