Theme 1.5 : Multiple wake impacts on machinesContact: Dr Philip Hancock, Surrey University Wind turbines, particularly those sited well within large wind parks such as will be increasingly the case offshore, are subject to complex impinging wake structures often coming from more than one machine upwind. The aerodynamic loading model developed in Supergen Wind 1 to investigate unsteady rotor loading from single incident wakes will be extended to multiple wake interactions. The work will involve time domain simulation of multiple wakes with validation against experimental data provided by Surrey University, followed by a study based on numerical simulation of the unsteady loading generated on immersed rotors. The study will use the numerical aerodynamic rotor loading model and be validated against experiments with an instrumented rotor in wind tunnel simulations of the atmospheric boundary layer (ABL) and upstream rotor wakes. Interacting with Theme 2.2. The work will report on the implications for blade fatigue life and provide inputs to control strategies (such as trailing edge camber control) to reduce the unsteady loading.
