Abstract
To study the wet natural frequency (in water) and dry natural frequency (in air) of a tidal current turbine, we conducted a two-year measurement campaign by deploying a full-scale prototype of the system. In this article, a theoretical model is developed and validated with the frequency measurements. It reveals the measured wet natural frequency of the system could approach half that of the dry one. The measurements also show that inflow turbulence is very important in the excitation of system resonances that can lead to system failure. We also briefly discuss how the wet frequency varies over a long period. (C) 2014 AIP Publishing LLC.
