| Abstract: | This paper investigates some important problems about the separated vortex,including the solution method of the incompressible and compressible viscous vortex core equations,the vortex breakdown region,the effects of the initial and the outer-flow parameters on the vortex breakdown,the mechanism of the vortex breakdown.A theoretical method simulating the separated vortex breakdown over the leading edge of the slender delta-wing was presented.The results about the effects of the initial parameters on the vortex breakdown at high speed motion,the motion feature of the compressible viscous vortex and the effect of the compressibility,were especially emphasized. |
