I'm studying the optimum arrangement of arrays of tidal stream turbines within tidal channels. This requires understanding the channel dynamics and the interaction of wakes from individual turbines. This is work is for my PhD through the University of Otago's Ocean Physics Group and NIWA's Marine Physics Group, supervised by Ross Vennell and Craig Stevens.
I'm using Gerris, to numerically model array layouts within a channel to compare power output from different array arrangements over a tidal cycle. The range of scales from turbine diameter (~20m), up to channel length (kms) and the reversing nature of the flow make excellent use of Gerris' adaptive mesh.
