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 。
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 characteristic, meanwhile, the flap leading-edge bubble separated flow is also illustrated.
