The phenomenon of three-dimensional separation of the flow over a slender body at high angles of attack is difficult to model and still challenging problem. The singularity of the flow is caused by mutual intervention of three-dimensional separation and separated vortices. In this study, the flow in the cross-flow separation region of an axisymmetric paraboloid at 30,40,and 50 deg angle of attack has been investigated experimentally by hot wire anemometer. The growth of turbulence in separated vortices is discussed by r.m.s. and probability density function of velocity fluctuation in addition to Reynolds stress.
