In solving the momentum equation which is more realistic BC's, mass flow rate or pressure drop. How can we justify mass flow boundary condition for BWR and SCWR? Is there any reactor practically working on controlled mass flow rate or something like that?
Any help is greatly appreciated. Thanks

Good day !
In my opinion BC with velocity distribution (= mass flow rate) at the inlet are more stable. If you want use pressure at inlet nozzle then you need to prepare long input branch (5-7) diameters.
Best regards,

I agree with Serge, the best BC are mass flow rate for the inlet, and pressure for the outlet.

But how can we give mass flow rate BC in reactors? is there any pump which is ideally providing constant mass flow rate?
