Effects of rotor deformation in wind-turbine performance: The Dynamic Rotor Deformation Blade Element Momentum model (DRD-BEM)

摘要

Understanding the multi-physics phenomena associated with blade dynamics constitutes a fundamental factor for the continuous development of wind-turbine technology and the optimization of the efficiency of wind farms. Large size differences between wind-tunnel models and full scale prototypes preclude the proper extrapolation of experimental data, especially when several coupled physical phenomena are acting simultaneously; thus the need of an advanced Virtual Test Environment where innovative designs could be tested at reasonable computational cost.
