I see now. So this is actually the region where some recovery takes place in the void between the gear before it sends that chunk across to the high-pressure side. I don't know all the proper terms but I think I get what you're saying.
Do you agree that the restriction is further upstream?
That over-driven, the whole cavity between the critical restriction and the pump gears is foam?
In this context, the bubbles collapsing in that region does make sense. I wonder if the taper isn't a feature just to stabilize that activity.
