An abrupt change of flow pattern is possible to occur at a certain position along the axis in a swirling flow field, when the azimuthal velocity is relatively large as compared with the axial velocity. The phenomena are known as the vortex breakdown. The aim of the present research is to clarify the essential properties of the phenomena, and to obtain reasonable explanation to the multiformity of the breakdown form as well. First, the elastoid-inertia oscillation of the rotating fluid in a cylindrical vessel is examined experimentally and theoretically. As the result, some characters of the inertial wave in rotating fluid are clarified. Then the vortex breakdown phenomena in a circular pipe are investigated.
