High-Fidelity 2-Way FSI Simulation of a Wind Turbine Using Fully Structured Multiblock Meshes in OpenFoam for Accurate Aero-Elastic Analysis

With increased interest in renewable energy, the power capacity of wind turbines is constantly increasing, which leads to rotor sizes. ever larger diameters, complex and non-linear fluid-structure interaction (FSI) effects on turbine aerodynamic performances become significant, can be fully studied using hi-fidelity 2-way FSI simulation. In this study, a two-way model developed implemented Openfoam investigate NREL Phase VI turbine. The structured multiblock (MB) mesh method used for fluid solid domains achieve good accuracy. A coupling based ALE ensure rotation deformation happen simultaneously smoothly. simulation results show that CFD (Computational Fluid Dynamics) CSD Structural -based provides high accurate multi-disciplinary design optimization (MDO).
