Mass flow rate calculation from steady state simulation

Using SimScale
1

Hello Support team,
I want to know how to calculate mass flow rate from steady state simulation of incompressible fluid, The steady state simulation is running for safety relief valve. Please help with this.

Thank you.

Hi @akash_rai,

Thanks for posting your question. Mass flow rate value is just available for Subsonic analysis type for now. For incompressible analysis type, it is not possible have this direct result yet. However you can get volumetric flow rate:

So in this case it will be a matter of using the density of the fluid to get this mass flow rate manually.

best,

As @goncalves said, you can use density to calculate the mass flow rate.
There is also a more detailed answer available. Check out the solution on this post SIDEPOD outlet mass flow rate - #2 by tsite
