Abstract

The dynamic stall characteristics of wind turbine airfoil under different diameter particles are modeled and simulated by CFD method. First of all, the continuous-phase and discrete-phase coupling is stimulated by the SST k-ω turbulence model for 2D NACA 0012 airfoil. After that, the accuracy of the SST k-ω turbulence model is verified, and the probability of the discrete-phase model is analyzed. The final step is to analyze the influences of particle diameter on the dynamic stall aerodynamic performance, and to obtain the distribution of concentration for the mass of particles with different diameters. The study presents that increasing the diameter of particles leads to larger lift coefficient when diameter of particles is less than 50 μm, resulting in more vortex volume near the leading edge of the airfoil, and plenty of particles gathering in the suction surface of the airfoil. As for the diameters equaling to 50 μm, the lift coefficient will decrease for any angle of attack of the airfoil movement to the oscillation cycle. The vortex volume and vortex intensity reduce because of the change of flow field at the leading edge of the airfoil. Consequently, a massive amount of particles accumulate at the pressure surface of the airfoil and the separation point shifts back. When it comes to the diameters larger than 50 μm, the larger attack angle has larger effect and vice versa, while lift coefficient decreases under both larger and small attack angles. The vortex volume near the leading edge of the airfoil decreases with the increasing of particle diameter, and a large number of particles are gathered on the whole pressure surface of the airfoil.
