| Abstract: | In Ihis paper, the phenomena of separated flows arc described. The separation criterion for three dimensional steady, viscous flows is given and the behaviour of separated flows is studied. The six models applied to separated flow's and related governing equations arc given. The numerical methods for solving N-S equations and the prospective of numerical simulation arc discussed. Especially, the problems of numerical simulation of Eulcr equations applied to separated flows arc studied. |
