Hi

I am having a domain (just a simple box domain). Inside the domain there are some chemical reactions taking place which results in release of heat, water vapor, carbon-di-oxide and ammonia. I want to disperse the CO2, NH and the water vapor out of the domain

Now i am blowing dry air through one end of the box which will help me carry away the contaminants (CO2, NH and water vapor). The other end of the box is exposed to atmosphere. So one side is Velocity Inlet(for air), other side is pressure outlet(as exposed to atmosphere).

I want to study the effectiveness of the air at a certain velocity to disperse the contaminants

I am not sure which model should i go for VOF or species transport model?

Kindly advise

Thanks in advance
