A small tidal marine turbine farm with simulated flow over irregular seabed. The current is going from left to right. The flow is three-dimensional over an area 6km x 6km x 500m.

The model uses computational fluid dynamics (CFD) to resolve the flow, with large eddy simulation (LES) modelling the turbulence. The turbines themselves are modelled using an adapted hybrid blade-element momentum technique, which dynamically reacts to the flow with continually changing power output, blade pitch, and RPM.

This video shows a vertical slice through the adaptive mesh, coloured by velocity magnitude.
