Calculation and Analysis of the Flow Passing through a Multi-Element Wing

  • Received Date: 30 Dec 1999

  • 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.
