It results lift improvement and drag decrease. Turbulence of oscillating jet forms a forced eddy at the suction surface of the airfoil and forced it break off from the surface at the same frequency of the oscillating jet.
数值模拟结果表明,定常吸气通过抽走翼型吸力面附近低能流体,增加了翼型吸力面附近流体的动能,提高了翼型的升力,减小了阻力;振荡射流将吸力面稳定的低能涡变成以一定频率脱落的强制分离涡,增加了翼型吸力面流体的动能,从而提高了翼型的升力。
