Abstract
The rotating flow inside an enclosed cylindrical rotor–stator cavity is studied. Within a certain range of governing parameters, vortex breakdown phenomenon can arise along the axis. Very recent papers exhibiting some particular three-dimensional effects, have concentrated new interest on this topic. The study is carried out by a numerical resolution of the 3D Navier–Stokes equations, based on spectral approximations. Three-dimensional behaviours of the flow and in the structure of the associated vortex breakdown are numerically exhibited for the first time in a cavity of large axial aspect ratio.
