摘　　要：传统Savonius型(S型)直叶片风力机与城市景观适配度不高,为此郁金香型垂直轴风力机逐渐受到行业与用户的青睐。为探明传统S型直叶片与郁金香型垂直轴风力机气动性能差异以及叶片型线对郁金香型风力机的影响,本文采用3040型线和半圆形型线设计了郁金香型垂直轴风力机并开展了全尺寸三维数值模拟研究。结果发现:对于S型直叶片风力机,3040型线的最高功率系数相较于半圆型线高出约6%。相比于S型直叶片风力机,郁金香风力机半圆型线及3040型线的功率系数在各个叶尖速比下均有轻微下降。对郁金香风力机性能进行分析后发现:在叶片弦长较大的区域,3040型线的扭矩值略高于半圆型线;在叶片中弦长较小的区域,半圆型线的风力机扭矩值较高,性能更好;当叶片弦长下降时,相比于半圆型线风力机,3040型线风力机的扭矩值下降速度更快,整体呈现非线性关系。Traditional Savonius-type(S-type)vertical blade wind turbine(VAWT)is not suitable for urban landscape,so tulip-type VAWT is favoured by industry and users.In order to find out the difference of aerodynamic performance between traditional S-type straight blade and tulip-type VAWT and the influence of blade profile on tulip-type wind turbine,the tulip VAWT is designed with 3040 and circular arc profiles,and the full-scale three-dimensional numerical simulation is carried out in this paper.The results show that the maximum power coefficient of the 3040 type profile is about 6%higher than that of the semicircle type profile for the S-type straight-blade VAWT.Overall,tulip-type VAWT is slightly lower than that of the S type straight-blade type wind turbine for each blade profile and blade tip speed ratio.For tulip type VAWT,the torque value of the 3040 type line is slightly higher than that of the semicircular type profile at large chord length area.And the torque value of the wind turbine of the semi-circular type profile is higher than that of the 3040 type profile in the region where the chord length of the tulip blade is smaller,and the performance of the wind turbine of the semi-circular type profile is better.When the chord length of the tulip blade decreases,compared with the semi-circular type profile,the torque of the 3040 type profile decreases faster,showing a nonlinear relationship.
