CFD for Wind and Tidal Offshore Turbines

CFD for Wind and Tidal Offshore Turbines encompasses novel CFD techniques to compute offshore wind and tidal applications. All the included papers have been presented at the 11th World Congress on Computational Mechanics (WCCM XI) organised together with the 6th European Conference on Computational Fluid Dynamics (ECFD VI) in Barcelona 2014. The book includes contributions of researchers from academia and industry.

This work presents analytical estimates for various flow scales encountered in cross-flow turbines (i.e. Darrieus type or vertical axis) for renewable energy generation (both wind and tidal). These estimates enable the exploration of spatial or temporal interactions between flow phenomena and provide quantitative and qualitative bounds of the three main flow phenomena: the foil scale, the vortex scale and wake scale. Finally using the scale analysis, we show using an illustrative example how high order computational methods prove beneficial when solving the flow physics involved in cross-flow turbines.

In particular, offshore wind and tidal turbines have seen increasing interest from academia, industry and government bodies, during recent years, as offshore sites present huge energy potential. The new engineering challenges presented by these technologies, together with the difficulty to undertake experimental test under offshore environments, have raised the interest on Computational Fluid Dynamics (CFD) to design appropriate turbines and blades, understand fluid flow physical phenomena associated with offshore environments and predict power production,
among others.
