Numerical Study of a Horizontal Wind Turbine under Yaw Conditions

Over recent years, considerable attention has been devoted to the optimization of energy production in wind farms, where yaw angles can play a significant role. In order quantify and maximize such potential power, simulation wakes is vital. present study, an actuator line model code was implemented OpenFOAM flow solver. A tip treatment applied involve effect induced by pressure equalization from suction sides. The Leishman–Beddoes dynamic stall (LB-DS) modified Sheng et al. employed consider phenomenon. developed ALM-CFD solver validated for NREL Phase VI turbine reference case. then used simulating yawed turbine, power variation compared with UBEM CFD. Overall, according obtained data, coupled well There improvement terms prediction phase delay that due stall. However, there still negligible overestimation deep conditions. Based on results, it suggested reduction output follows cosine X function angle. visualizing wake, results demonstrated current ALM satisfying enough simulate skewed wake vortices trajectory. advancing retreating blade captured. It found led concentration velocity downstream, resulting lower deficit broader area, which essential farm optimization.
