Default Mass Conservation
Posts: n/a

I am injecting Helium in a 10m X 2m Rectangular Closed domain. The mass flow rate is 0.0017Kg/s.This is unsteady problem.

After few seconds I am calculating the total mass injected by Time*mass flow rate. This should be equall to mass averaged species mass fraction which is reported in Volume integrals. But i am getting 10 times higher values by Fluent. Can anyone suggest what the problem is.

Thanks in advance.
