Hi all

I am thinking to simulate a CO2 decay inside a ventilated room (single inlet, single outlet)and validate my model. I have the following experimental data.

- impulse input concentration of CO2 at the inlet -Ventilation rate -CO2 concentration decay record at 10 positions inside the room

Is there some one who did the same kind of simulation before, please help, It is the first time to work for me with concentration.

thanks cfx4.3user
