Comparison between one-way and two-way fluid-structure interaction simulations of a horizontal tidal current turbine
CFD and FSI methods have been used to predict the performance of tidal current turbines.However, few researches compared the difference of various FSI methods to power efficiency and structural response of turbine blades.In this study, we first used BEM method to design and optimize hydrofoil.Then one-way and two-way FSI methods were realized in ANSYS CFX to compare the difference.The results showed that one-way FSI method overestimated the power efficiency and underestimated tipvortex strength comparing to two-way FSI.However, blade deformation and stress distribution presented limited variations for different methods.We also found that the maximum blade displacement and Von-Mises stress amplitude had nearly a linear relationship with TSR, while maximum stress location was unchanged in different working conditions.
