Understanding Fish and Turbines

Written by

Illustration of a fish encountering an underwater turbine. Text reads, "Fish detect turbulence signals using the lateral line system. Turbulence as viscous hydrodynamic disturbances."

Using LES, scientists describe the flow downstream of the spinning turbine. Flow is moving left to right, colored by velocity magnitude. Text reads, "3D periodic vortical structures, marking highly turbulent wake"

With the turbulence simulation in place, researchers look at how real fish trajectories compare to the flow. Text reads "Merging experimental fish trajectory with LES results." The fish is circled in a dashed green circle labeled "Near pass".
