Investigating Aeroelastic Performance of Multi-MegaWatt Wind Turbine Rotors Using CFD

Recent trends in wind power technology are focusing on increasing power output through an increase in rotor diameter. As the rotor diameter increases, aeroelastic effects become increasingly important in the design of an efficient blade. A detailed understanding of the fluid elastic coupling can lead to improved designs; yielding more power, reduced maintenance, and ultimately leading to an overall reduction in the cost of electricity. In this work, a high fidelity Computational Fluid Dynamics (CFD) methodology is presented for performing fully coupled Fluid- Structure Interaction (FSI) simulations of wind turbine blades and rotors using a commercially available flow solver, AcuSolve. We demonstrate the technique using a 13.2 MW blade design.

DSHplus and AcuSolve - Fluid Power System Simulation Hand in Hand

This was a 2013 European ATC presentation given by Dr. Heiko Baum from FLUIDON Gesellschaft für Fluidtechnik mbH. Today the dynamic behavior of complex fluid power systems is typically simulated with 1D system simulation programs such as DSHplus. But, if accuracy requires modeling details at component level this technique comes to its limits. The representation of pressure losses of complex flow channel geometries, such as the bores in hydraulic manifold of heavy machinery or the customized pipe layouts in automotive applications or aerospace applications, cannot be achieved with a series connection of 1D system components.
