Reactor - axissymmetric

Hello everyone!

I have some doubts regarding the mass flow rate specification in boundary conditions (Ansys Fluent 19.2).  I know the inlet mass flow rate for a real 3D circular shape reactor. Now if I consider 2D axissymmetric reactor,  then for the inlet should I somehow change this mass flow rate value ? Because honestly when changing nothing, I obtain very small velocity field.

Cheers

I mean like we model only half of it, so some division by 2, or  something with the PI number?

No if you are specifying it as mass flow rate that you correspond to the 360°.

Best regards,
