摘要: 采用中心差分的有限体积方法和分区技术求解了N-S(Navier-Stokes)方程,在分区求解技术中采用了满足通量守恒的内边界耦合条件.分析讨论了三维襟翼的绕流流场,对"剪刀差"处的三维分离进行了探讨,初步揭示了绕流的主要特征及对附近物面压强的影响.同时,分析了三维襟翼前缘的分离流动.

Abstract: The N-S equation is solved using a finite volume method with central difference scheme and a domain decomposition technique, an internal coupling condition satisfying the conservation of flux is used in the domain decomposition method. The complex flow field passing through a three-dimensional wing with flap is analyzed, the main features of the separated flow field are shown, it is discussed the formation of the flap side-edge vortex and its influence on the aerodynamics characteristics; meanwhile, the flap leading-edge bubble separated flow is also illustrated.
