RESUMO

The steady axisymmetric flow around a body of revolution in the uniform flow of an incompressible fluid at high Reynolds numbers is considered. Based on an asymptotic analysis of the system of Reynolds equations for time-averaged functions, it is shown that the flow at the body scale is described by the solution of the problem of the flow with a free-stream surface in accordance with the Kirchhoff scheme. The flow is turbulent in the closure region of the separation zone and the wake. Outside these regions, the turbulent stresses are exponentially small. The streamwise and transverse sizes of the separation zone are rather large; in the main approximations, this zone has the form of an ellipsoid with a small relative thickness.
