The extreme regimes of spatial turbo-pumps are sources of complex hydrodynamic phenomena that may be critical to their operation: appearance of instabilities, excitation of vibrational modes, new sources of dissipation and heat transfer. Understanding and accurately predicting the hydrodynamics in these systems play a crucial role in the stability and the performance of these machines.
