Experiments of the flow around circular cones normal to a flat plate were conducted using the flow visualization method. The horse shoe vortex around the circular cone was observed nearby the flat plate. On the other, the arch type vorticies existed behind the circular cones. In a detailed observation, it was shown that the secondary flow fluid motion with three-dimensionality in the vertical direction on the back face of the cones and the bevel flow on the side surface of them existed. Comparing to the experiments, results of calculation were good agreement and represented behaviors of vortex motion in the wake flow.
