| 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. |
