The non-monotonic distribution of the radial velocity component is important for the onset of the driving force of the angular instability. This instability and the existence of the radial fluid motion give rise to the angular volume force. The strong gradient of entropy in the boundary layer of the inner rotating conical cylinder is a dominant source of vorticity. The solution presented as a result of the theoretical analysis includes discussion and comparison with rough preliminary experimental data. The rotating fluid action is obviously of interest for further research. An improvement in efficiency is the genuine motive for further research.
