Hello friends.
I'm modeling a shell and tube heat exchanger in Fluent.
It contains 27 tubes. All tube inlets are organized in one component as "tube inlet" with 0.02 kg/s mass flow rate.
Will this mass flow rate be automatically divided between tubes by fluent (like .02/27 kg/s) or I have to divide it?
Thanks for reply.

If the tube inlets are all one boundary zone then I would expect that they would share the mass flow rate of 0.02 kg/s, whereas having 27 individual inlet zones would have a total mass flow rate of 27*0.02 kg/s. Regardless, you should double check with Postprocessing > Reports > Surface Integrals to ensure that the inlet condition is what you intended.
