Analysis of Aerodynamic Performance for Lift Wind Turbine and Lift-drag Wind Turbine
摘要
Abstract
In order to deeply research aerodynamic performance for lift wind turbine and lift-drag wind turbine , based on the CFD software this article used k-ωSST turbulent model ,adopted double moving mesh technology ,carried out field calculation on lift wind tur-bine and lift-drag wind turbine, calculated their start-up wind speed and cut-in wind speed, research their aerodynamic performance under low wind speed .The result showed that lift-drag wind turbine had the larger starting torque , smaller cut-in wind speed and smal-ler start-up wind speed ;lift-drag wind turbine was easier to start-up than lift wind turbine at low wind speed while the lift-drag wind tur-bine’s output power was larger before stall , but its output power was lower than that of lift wind turbine after stall .关键词
