Development of a method for numerical modeling of the separation flow at the entrance to a rectangular exhaust channel with sharp edges

We have developed a method for mathematically simulating flow separation at the entrance to exhaust channels of rectangular shape, using stationary discrete vortices in an ideal incompressible liquid full spatial setting. When designing model, straight and curvilinear quadrangular vortex frames, horseshoe-shaped were used. Using computational procedure computer program, outline zone entry channel with sharp edges axial velocity air are determined. The results compared studies by different authors, as well calculations methods theory functions complex variables slotted exhausts earlier obtained us calculation square opening means non-stationary quasi-symmetric further direction research will be related investigation flows detached hoods method, CFD methods. Then it is necessary identify regularities change local resistance coefficient hood, shaped found outlines zones.
