A one-equation model previously tested for parabolic flows and 2-D separated flows was implemented for rotating flows. Flows in rotor-stator disk systems, and in sealed cavities between contrarotating and corotating disks, were calculated and compared with known experimental and numerical data. For buoyancy-driven flow in a rotating cavity, an analytic solution for the turbulent regime was obtained. [S0098-2202(00)01302-X]
