Specifically, I have a chimney that is emitting smoke and nearby is an inlet duct that is drawing air for cooling a certain device. I need to know the percentage of smoke (contaminated air) that is drawn into the duct.
Osama Ragab, thanks for your reply, but the link you sent is simply an advertisement for Solidworks Flow Simulation - software to which I already have access. I need tips specifically on how to use it for simulation of the flow of miscible gases.
