产生RvKVS涡型的可能性较小。LEV涡型导致轻动态失速,造成VAWT叶片发生高频俯仰振动,但对叶轮转矩和VAWT功率影响不大。RvKVS涡型的出现,伴随叶片升力和转矩幅值增大以及平均推力的产生,会使VAWT叶片扭矩载荷增大,也会使叶轮转矩和输出功率提升。据此提出基于VAWT的新式风墙构型,在继承Nes浮式风墙构型优点的基础上,进一步提升了功率系数和风能输出密度。
In order to study the aerodynamic response of the vertical axis wind turbine (VAWT) foil to different wake vortex shedding patterns
an analog experiment of the sinusoidally pitching foil was carried out based on the similarity of the variation of angle of attack. In the chord-based Reynolds number range of ~

three vortex patterns are identified in the wake: leading-edge vortex (LEV) pattern
undulating wake (UW) pattern
and reverse von Kármán vortex street (RvKVS) pattern. For VAWT
the reduced frequency

. The light dynamic stall caused by the LEV pattern makes VAWT foil pitch at a high frequency
but the rotor moment and the VAWT power are not affected significantly. The appearance of the RvKVS pattern causes the increase of amplitudes of lift and moment coefficients as well as the production of mean thrust on the foil
which increases the torque load on the foil
the r
otor moment
and the output power. Based on the results and discussions of the analogue experiment
a new configuration of the wind-catching wall with two-straight-foil small-scale VAWT units is proposed
which further improves the power coefficient for a given area of land
compared to the Nes configuration of the floating wind-catching wall with horizontal-axis wind turbine units.
