5. Dimensional analysis
This analysis was inspired by Tremende's doctoral thesis .
In the presence of an initial two-phase mixture (e.g. a liquid-gas mixture), the performance of any pump, expressed in terms of pressure coefficients and flow coefficients, is always degraded compared to the single-phase case. The parameters influencing the level of degradation depend on the type of pump (and therefore on their specific speed Ω), the configuration of the two-phase flow itself, the angular speed of rotation of the...
