Multi-physics simulation of wind turbines
High-fidelity multi-physics simulations
of large structures constitute a key technology for the design and optimization of high-performance wind turbines. They critically support efficiency optimization, weight reduction, and the application
of new materials and can reliably
predict important failure mechanisms such as aero-elastic instabilities or composite fatigue. CEGE researchers are developing computational methods that seamlessly integrate parametric geometry modeling, isogeometric structural analysis, embedded domain computational aerodynamics, and fluid- structure interaction. The resulting simulation framework can be readily applied for the simulation-based design of wind and hydrokinetic turbines. Due to the ubiquitous deployment of turbomachines as a key enabling technology, even moderate enhancements in energy conservation can significantly improve global energy efficiency. Therefore, novel computational methods that facilitate simulation-based design optimization have a significant impact on improving sustainability. [40–42]
