摘要
为了计算亚音速和跨音速三维机翼阻力,文中利用尾迹积分法对空气产生的阻力进行了数值计算研究。结果表明,尾迹积分法相对于物体表面积分,可以把亚音速时有粘流中机翼的总阻力分解为黏性阻力和诱导阻力,跨音速时有粘流中总阻力分解为黏性阻力、诱导阻力和激波阻力,是一种可行的阻力预测方法。
The wake integration method was employed to predict wing drag in subsonic and transonic flow. Compared to traditional surface integration method, the wake integration method introduced was able to decompose the total wing drag in to its physical components-viscous and induced drag in subsonic flow; viscous, induced and wave drag in transonic flow. The result indicates that wing drag prediction based on wake integration is a reliable, viable method, and provides better understanding of drag generation sources
