Beschreibung:
This study develops a high-order numerical model, AL-PyFR(DAWT), to analyze multi-rotor diffuser-augmented wind turbine (MRDAWT) systems using the actuator line method within PyFR. The model is validated against a 5-rotor DAWT experiment, accurately capturing asymmetric rotor power, wake interactions, and diffuser effects. A parametric study on a 9-rotor system shows rotor spacing and tip speed ratio strongly affect power output and efficiency, highlighting the need for system-level optimization.
