I'm hardly a hydrodynamics expert, but I would think that total storage volume in the system is the other critical factor. A chamber stores that volume close by. But a long simple tube with multiple feeders would provide a similar sort of effect - i.e. once the system empties some of itself, the pressure relieves enough that the lower water begins to flash to steam as well. This might explain the water phase/steam phase system. Or I could be applying far too simplistic an explanation as well.
