Abstract
In this study, aeroelastic response analyses have been conducted for a 3D MW‐Class wind turbine blade model. The complex composite laminated blade rotates in the unsteady fluid. Advanced computational fluid dynamics (CFD) and computational multi‐body dynamics (CMBD) coupling method has been developed in order to investigate aeroelastic responses of the rotating composite blade in unsteady fluid. Reynolds‐Averaged Navier‐Stokes (RANS) equations with k‐ε turbulence model were solved for unsteady flow problems of the rotating turbine blade model, and modal analyses of rotating wind‐turbine blade have been conducted by using the general nonlinear finite element program. A fully implicit time marching scheme based on the Newmark direct integration method is used for computing the coupled aeroelastic governing equations of the 3D turbine blade for fluid‐structure interaction (FSI) problems. Detailed dynamic responses and instantaneous velocity contour on the blade surfaces which considering flow‐separation effects were presented to show the multi‐physical phenomenon of the huge rotating wind‐turbine blade model.
