Search under:venturi,venturi tube,aspirator,venturi tube simulation,venturi tube flow calculator.

BTW: water is a refrigerant
Would it be possible to put another form of vacuum device between the reservoirs and the Mazzei injectors? If I could find some kind of vacuum pump which can be driven by the excessive flow of fluid coming from the injector, that vacuum pump would then do the real work. The Mazzei injectors produce such an excessive flow for this system, that they really beg for something to do with that flow. Granted, they don't produce hydraulic pressures. But something should be able to be done with that flow to contribute to the overall design.

The first-stage vacuum device(s) would create the vacuum necessary for boiling the water. The injector then would only have to move that vapor into the fluid stream.
