Numerical Study of Flow Around Iced Wind Turbine Airfoil

摘要

AbstractThis investigation analyzes the impact of ice accretion on the aerodynamic coefficients of a wind turbine airfoil. Three blade sections located at different radial positions were analyzed. Numerical simulations were conducted over a two-dimensional clean and ice-accreted NACA 63–415 airfoil at various angles of attack. The results for pressure, lift, and drag coefficients were inspected at an angle of 13° for which experimental data were available. The streamlines around the clean and iced airfoil were also inspected, in order to evaluate the ice impact on lift and drag. The simulations were carried out using the commercial package FLUENT, and turbulence was addressed with the SST k - ω) model.
