摘要：

The two-dimensional unsteady viscous flow of H type vertical axial wind turbine with pitch angle changing is numerically investigated by using CFD numerical simulation method in this paper. An experiment model with three blades of H type wind turbine is selected; Cartesian grid dynamic simulation method and SST turbulence model are used. Power coefficients with tip ratios 2.15 and 2.27 are compared in the condition of pitch angle changing and without pitch angle. In addition, variation of loads of single and three blades with azimuth is investigated. Two-dimensional unsteady flow details through vortices contours with azimuth in one rotation cycle are analyzed. The cause of the wind turbine aerodynamic load increased after pitch angle changing is revealed. © 2015, Science Press. All right reserved.
