Separation flow past bodies with fixed separation sites

Separation flow past bodies was studied by way of computer experiments. Flow in a continuous medium at a high Reynolds number (Re = 100,000-ten to the 7th power) was simulated on the basis of Euler equations for nonsteady flow of an ideal medium and by two fundamentally different methods. The method of discrete vortices was used for solving nonlinear steady-state and transient-state equations applicable to bodies in incompressible media. This method yielded reliable results in analysis of flow past carrier surfaces with vortex trails, plane flow with initial Prandtl or Karman vortex trail behind plates, plane flow with mixing and rotation in vane cascades, three-dimensional flow with acceleration past bodies made of permeable materials, and three-dimensional flow with transformation of vortex sheet into vortex filaments at wings. The method of large particles was used for flow of a gas at subsonic and supersonic velocities, plane axisymmetric flow, and three-dimensional flow with vortex spirals. The results obtained by both methods were verified by other mathematical methods.
