摘要

The flow field of 1.2MW wind turbine rotating wind wheel by SST k —ω was simulated. Power output and turbulent kinetic energy were compared with single blade's. The interacting between rotating blades is also analyzed. Computational results showed that the attaches vortex shedding from upper rotating blades was occurred during the operation, which lead to the change of lower blades environments, which has great influence on total moment and power output. It is very necessary for improving efficiency and reaching optimal operating condition to consider the interacting between blades during optimization design.
