Hello,

Let's have a water boiler - closed tank full of water. The hot water is outleted from the top, cold water is inleted in the bottom.

Inlet water temperature is to be fixed. Outlet temperature changes accordingly to heat ballance and transfer in the system.

To keep the ammount of consumed heat, I need to change the inlet=-outlet mass flux (or velocity) on deltaT of the system. With other words: to control mass flux by outlet water temperature.

How to realize this ? Give me a direction, please.
Is it a case for groovyBC ?


It should be the start of some design test case. The idea is to solve it in transient. Is the buoyantBoussinesqPimpleFoam suitable solver for that simple case?


Thanks a lot
