The flow in the cross-flow separation region of an axisymmetric paraboloid at high angles of attack has been investigated experimentally by smoke visualization technique and hot wire anemometer. The relations between separated vortex and the other flow regions are characterized by calculating two-points velocity cross- correlation.
