... in the central jet. When one or both of the disks were heated, the flow in the cavity became non-axisymmetric, and cyclonic and anticyclonic vortices were observed, as shown schematically in Fig. 4 . Farthing et al. used the so-called linear equations for rotating flows to explain that, as stated above...
