3 different CO2 concentrations in one room -- CFD Online Discussion Forums

January 3, 2013, 13:35	3 different CO2 concentrations in one room	#1
wangy1767 Member yang Join Date: Jun 2012 Posts: 39 Rep Power: 14	Dear all, I want to simulate a room with 3 different initial CO2 concentrations in the top (high CO2%), middle (middle CO2%) and low (low CO2%) parts of the room, separately, using CO2 as an additional variable. There are 3 inlets of fresh air flow in the low part of the room and one outlet in the top of the room. Hence, whether I need create a box with 3 bodies as 3 parts of the room in ICEM? Then whether I need create 3 domains and 2 interfaces for the room in CFX-Pre? Or could you users please give me some suggestions for the case in details? Many thanks in advance! Br. yang wang
