Laminar flow separation on a spheroid at incidence
Abstract
Changes in separation patterns and the associated flow topology have been investigated in steady, incompressible, laminar flow on a spheroid over a range of incidence angles. Numerical solutions of the full Navier-Stokes equations are obtained for the case of axes ratio 6, at a Reynolds number 50,000, for incidences up to 30 deg. It is concluded that a region of closed separation over the rear of the body can be identified by singular points in the skin-friction lines, or limiting streamlines, on the body surface. At zero incidence, the solution is found to be axisymmetric over most of the body, but it became three dimensional in the vicinity of separation.
