ICING DISTRIBUTION OF ROTATING BLADE OF HORIZONTAL AXIS WIND TURBINE BASED ON QUASI-3D NUMERICAL SIMULATION

ABSTRACT
For researching on the rules of icing distribution on rotating blade of horizontal axis wind turbine, a Quasi-3D method is proposed to research on icing on rotating blades of horizontal axis wind turbine by numerical simulation. A two-dimensional and three-dimensional method of evaluating the irregular shape of ice has been established. The model of rotating blade from a 1.5 MW horizontal axis wind turbine is used to simulate the process and shape of icing on blade. The simulation is carried out under the conditions with four important parameters including ambient temperature, liquid water content (LWC), medium volume drop diameter (MVD) and icing time. The results reveal that icing mainly happens on 50%~70% of the blade surface along wingspan from tip to root of blade. There are two kinds of icing shapes including horn shape icing and streamline shape icing. The study can provide theoretical basis and numerical reference to development of anti and deicing strategy for wind turbine blades.
