Finite Element Analysis to Assess Fish Mortality from Interactions with Tidal Turbine Blades

February – December 2017

The research project used finite element analysis (FEA) to simulate the impact of a tidal turbine blade on fish, and assess whether mortality of marine life can be expected in such an event.
