Mass flow calculation in a 2D ANSYS model

theo1 · May 11, 2013, 07:27

Hello,

I am well ware this is most probably a very basic question, but here I go...

I am modeling a 2D heat exchanger in ANSYS (water in a duct flowing over heated tubes). The inlet boundary condition is a velocity (0.5m/s), the duct diameter is 0.1345 m. Is it possible to get a mass flow rate for the fluid in the duct? I have sen other posts and am rather unsure of the result it gives me.

Any help would be hugely appreciated.

Thanks in advance!

If you know the cross sectional area of the duct, can't you use

density*Area*Velocity

to get the mass flow rate?
