Research on the Parametric Modelling Approach of Vortex Generator on Wind Turbine Airfoil

چکیده
Counter-rotating vortex generators (VGs) are typically employed to delay airflow separation on wind turbine blades. Large-size blades equipped with small size VGs make the computational fluid dynamics (CFD) researches require a great deal of resources. Parametric models can effectively improve numerical research efficiency VGs. In order accuracy such parametric models, this study proposed series modeling approaches determine positions adding source term in Cartesian coordinates, VG core radius, etc., airfoils. These techniques integrated maximum circulation algorithm by considering interactions between pairs predict performance DU91-W2-250 blade section The model and an entity at different angles attack (AoAs) implemented section. Our approach is validated using experimental data. Comparisons demonstrate strong agreement modelled results, proving high two models. results then compared analyzed incoming flow velocities AoAs verify universality approaches. reveal consistency structure, velocity profile above surface distribution pressure coefficient calculated This proves demonstrates potential replacing model. expresses parameters program, which arrangement

Effect of Wind Speed and Load Correlation on ELCC of Wind Turbine Generator
Utilization of wind turbines as economic and green production units, poses new challenges to the power system planners, mainly due to the stochastic nature of the wind, adding a new source of uncertainty to the power system. Different types of distribution and correlation between this random variable and the system load makes conventional method inappropriate for modeling such a correlation. In...
