摘要
Aerodynamic characteristics of small-scale of Archimedes spiral wind turbine blade are presented in this paper.Numerical simulation for aerodynamic performance of the blade was carried out for different configuration of inlet velocity.Numerical approaches on the prediction of aerodynamic characteristics of the blade were performed by using XFlow which has been written based on lattice Boltzmann method.Wall-Adapting Local Eddy-viscosity(WALE) model has been applied as is has a good properties near and far from solid body and wall for both laminar and turbulent flows.Particle Image Velocity(PIV) has been used to prove the obtained results of numerical simulation and investigate the aerodynamic physiognomies of the spiral wind turbine.In order to verify the numerical analysis velocity behavior around the blade are captured and compared with experimental results.The prediction of velocity outlines by using XFlow is in a good agreement with the trajectory and greatness of tip vortices engendered by the Archimedes spiral wind turbine blade from experimental results.
