Numerical simulation and analysis on aerodynamics of three-element airfoil in ground effect

  • 摘要: 通过数值模拟方法研究多段翼型的地面效应,采用有限体积法求解质量加权平均平均Navier-Stokes(N-S)方程,湍流模型采用Spalart-Allmaras (S-A)模型,采用滑移壁面模拟地面的相对运动.计算结果分析表明:随着飞行高度的降低,多段翼型的升力、阻力和低头力矩均减小;升力系数的减小主要是由于地面效应引起流场改变,下翼面压力的增加量小于上翼面吸力的减小量引起;地面效应使翼型上表面逆压梯度增加,后缘襟翼容易出现分离.
