| 摘 要： | 应用Gao-Yong湍流模型模拟了吹气对翼型表面分离流控制的影响.结果表明,该模型不仅能够对翼型绕流的分离点、表面压力分布、升阻特性等做出较好预测,而且还能模拟出控制分离的吹气效果:①有效消除翼面分离涡;②"裹携"翼面来流进一步提高升力系数.提高吹气动量系数,升力曲线上移的幅度也相应增加;而吹气角度对吹气射流"裹携"作用的强弱也有一定的影响,当吹气方向相对于翼弦偏上时,吹气射流"裹携"来流与消除分离涡的作用增强,升力提升更为明显.

| Abstract: | Gao-Yong turbulence model was applied to simulate the influence of blowing jet on the flow separation control of the airfoil surface.The results show that Gao-Yong turbulence model can not only successfully simulate the location of separation and the aerodynamic force coefficients,but also effectively simulate the blowing effect of flow separation control.Other than increasing lift by inhibiting flow separation vortex on the airfoil surface,the blowing jet can also induce much higher lift through the "packa... |
