The Numerical Simulation of Aerodynamic Performance for Wind Turbines’ Blade Wheel

Abstract:

It’s necessary to research on the interaction of blade wheel with incoming flow. The CFD method was used in this paper for numerical simulation of the aerodynamic performance for wind turbines’ blade wheel at rated wind speed. The first thing was the establishment of wind turbine dynamic model of blade wheel. Then using Fluent software to simulate the three-dimensional flow field around it. The visual images on pressure distribution，flow rate distribution and velocity vector of the blade were obtained. Also, the load and the torque of the blade were calculated. The reliability of this numerical simulation is inspected in this paper. Some technical parameters and instructional suggestions about how to design the blade as well are proposed.
