低Reynolds数下合成双射流控制结冰翼型流动分离的数值模拟
|
摘要
通过FLUENT软件数值模拟的方法,分别对结明冰、混合冰、霜冰翼型的气动特性进行了研究,分析了合成双射流对改善结冰翼型流动分离的影响规律.结果表明:3种冰形均破坏了翼型的流线型,对翼型的气动力特性有不同程度的影响,其中霜冰对翼型气动力特性影响最小,明冰对翼型气动力特性影响最大,混合冰介于两者之间.开启合成双射流激励器,在小攻角情况下,结冰翼型的气动特性得到了有效的改善.而在大攻角情况下,合成双射流激励器不能完全消除分离涡,但可以推迟分离涡,分离涡厚度增加,分离涡最厚点推后.
The numerical simulation of a wing with glaze ice, mixed ice and rime ice was carried out by FLUENT. The effect of dual synthetic jet on flow separation for iced airfoils was analyzed. The results show that these three ice shapes change the streamline of the wing, and the aerodynamic characteristics of the wing are affected to different degrees. The effect of rime ice on aerodynamic characteristics of the wing is the least, and the effect of glaze ice is the largest. Because of the synthetic jet actuator, the aerodynamic characteristics of iced airfoils are improved effectively at small angle of attack.At high angle of attack, the actuator can not inhibit flow separation for iced airfoils completely. But it can effectively delay the separation vortex.
