Hi everyone,

I'm new on this forum, but i saw that simulations about perforated plates had been discussed already but i didnt find solution to my problem.
I am working on CFX on part-time, so i didnt explore most of possible options...

Let me explain... (and sorry if my english is approximate sometimes...)

I want to simulate a thin perforated plate in a HVAC application.
I would like to use perforate plates as inlet, outlet and as "connexion" between two domains (representing 2 different rooms for example).

I am looking for the good method to obtain the right flow and the right velocity on the total surface

For example,
1x1m plate, 50% open surface.
A flow through the plate of 1m3/s.

The resultant velocity at the plate outlet would be 2m/s.

Is it possible to obtain this velocity with a 1m² inlet/outlet in my model ?


I tried to simulate the plate as a porous domain between 2 rooms. But my first results show an incorrect air profile at the outlet of the porous domain.

I tried to understand how porous domains work with the CFX tutorial (catalytic converter)...

If my description is not accurate enough or hard to understand, dont hesitate to ask me more informations.

Waiting to read you...

Thanks !

Julien
