Nonlinear frequency domain solution method for aerodynamic and aeromechanical analysis of wind turbines

The aerodynamic simulations of wind turbines are typically carried out using a steady inflow condition. However, the aerodynamics and aeroelasticity turbine blades can be significantly affected by wakes due to environmental conditions or presence neighbouring turbines. In this paper, effects flow unsteadiness on rotor investigated. It is found that wake have an impact field around it could also influence turbine. One distinctive features paper application highly efficient nonlinear frequency domain solution method for modelling harmonic disturbances aeromechanical analysis A test case selected as well validation used. different material properties along with large vibration amplitude parameter known damping blade investigated in present work. Compared conventional time methods, which require prohibitively computational cost solving turbines, proposed reduce one two orders magnitude.
