Abstract
Tidal energy industry is currently involved in a strong growth phase and it is
expected to play an important role as far as meeting the renewable energy
targets is concerned.
The product development strategy adopted by tidal energy companies is
nowadays broadly based on a gradual increase of the prototypes scaling factor.
Thus, the prediction of important engineering quantities such as drag at
intermediate stages becomes of vital importance for developers.
The diversity and complexity of the geometries adopted by second-generation
tidal energy converters preclude the use of already existing drag scaling
methods conceived for specific applications such as ship design. In this context,
numerical simulations are regarded as a suitable alternative.
This study addresses the use of Computational Fluid Dynamics (CFD) to
determine the drag of the unique tidal energy converter developed by
Sustainable Marine Energy (SME) called PLAT-O.
Several preliminary simulations were performed on the isolated PLAT-O
components. The results were compared with previous CFD studies devoted to
similar form bodies and good agreement was found.
Following this stage, the drag predictions on the whole PLAT-O device were
undertaken and compared to existing experimental data. Significant differences
between them were observed.
This work has demonstrated that a RANS flow solver is not an efficient tool to
predict the resistance of a small-scale PLAT-O device. In addition, this study
has predicted that CFD will be suitable to assess the design of larger-scale
prototypes.
