The temporal behaviour of the three-dimensional flow (that does not vacillate) in a non-isothermal rotating cavity with an axial throughflow of air is explored. This behaviour is contrasted with that in a heated rotating annulus. Generally, for both systems, the ratio of the flow angular velocities to the system boundary's (angular velocity ratios) are found, even close to boundaries, not equal to unity. However, for the cavity, the angular velocity ratio tends to unity in the vicinity of the throughflow air. Both systems exhibit similar radial distributions of averaged temporal velocity gradient components. Most unsteadiness is found to correspond to regions of high tangential velocity gradients. As a result of the flow drift, these spatial gradients are converted to temporal gradients. The cavity heat transfer is shown to vary almost as much in the tangential direction as in the radial. For the present flows, computations suggest judicious coordinate system angular velocity choices may reduce demands on both convective term treatments and computer resources.
