风电机组多部件融合气动分析
Aerodynamic analysis of multi-component fusion of wind turbine
摘要
Abstract
SL1500/61 which is Sinovel 1.5 MW wind turbine with variable speed constant frequency doubly-fed induction generator is chose as the basic model. Hub with three different types of nose cone and blades are fusion modeled, then verified the rationality of the whole model through numerical simulation method. Under extreme wind velocity of three conditions analysis aerodynamic characteristics near the flow fields of nose cone and nacelle, the results show that blades' wake velocity difference is about 1 m/s, there is largest high pressure area at the frond part of resistance-type nose cone, with a W-type nose cone e pressure characteristics of nacelle surface are superior to other types,eddy viscosity is obvious different with the surface of nose cones. Blade fusion technology could remarkably solve flow of angular area between the blade root and nose cone endwall to reduce the error of diversion effect.关键词
