Abstract
Icing accretion on wind turbine will degrade its performance, resulting in
reduction of output power and even leading to accidents. For solving this
problem, it is necessary to predict the icing type and shape on wind turbine
blade, and evaluate the variation of aerodynamic characteristics. In this
paper the icing types and shapes in presence of airfoil, selected from blade
of 1.5 MW horizontal-axis wind turbine, are simulated under different
ambient temperatures and icing time lengths. Based on the icing simulation
results, the aerodynamic characteristics of icing airfoils are simulated,
including lift and drag coefficient, lift-drag ratio, etc. The simulation
results show that the glaze ice with two horns presents on airfoil under
high ambient temperature such as -5?C. When ambient temperatures are low,
such as -10?C and -15?C, the rime ices with streamline profiles present on
the airfoil. With increase in icing time the lift forces and coefficients
decrease, and the drag ones increase. According to the variations of
lift-drag ratios of icing airfoil, the aerodynamic performance of airfoil
deteriorates in the presence of icing. The glaze ice has great effect on
aerodynamic characteristics of airfoil. The research findings lay
theoretical foundation for icing wind tunnel experiment.
