Abstract
Three-dimensional separation of the flow over a slender body at high angles of attack is difficult to model and still a challenging problem. The singularity of the flow, such as large side forces and yawing moments, is caused by mutual interactions of three-dimensional separation and separated vortices. In this study, the flow in the cross-flow separation region of an axisymmetric paraboloid at 40 and 50 deg angles of attack has been investigated experimentally by hot wire anemometer. Reynolds numbers are in the range from 1.8×10^4 to 7.5×10^4 referred to the base diameter.
