Background technique
It usually will be installed several vortex generators on modern wind generator blade, for generating high energy wingtip vortex, inhibit
Aerofoil profile upper surface flow separation postpones stall, improves generated energy.Common vortex generator structure includes two as shown in Figure 1
Symmetrical fin and a pedestal, fin are typically normal to pedestal and in a certain angle with flow direction.About fin
Shape, the design scheme for also having many patent disclosures different at present.The geometric shape of vortex generator generates class in flow field
Like the wing tip " whirlpool " of aircraft wing tip, high-velocity fluid energy outside boundary layer is brought into boundary layer by rotation by wing tip " whirlpool "
It is interior, the ability that boundary layer overcomes adverse pressure gradient is increased, the burble point of flow boundary layer is delayed, vortex generator increases leaf
Maximum lift coefficient in piece operating condition improves lift resistance ratio, and then improves wind energy capturing efficiency.
There is an angle in existing vortex generator and flow direction, due to the presence of the angle, increase fin vertical
Directly in the projection on flow direction, form drag is increased.Since the fin of vortex generator is " eight " font arrangement, it will lead
It causes the resistance coefficient of aerofoil profile to increase, and then influences the whole of vortex generator and increase effect fruit.If but without this angle, parallel current
Vortex generator fin is skimmed over, the favorable current vortex structure of fin induction is very faint, and it is extremely limited to the disturbance of tail, inhibit stream
Dynamic separating effect is bad.
