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.

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

Best regards,

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