how can simulate mixuring of two gases?

immortality · March 19, 2013, 14:26

i want to simulate a closed tube of stationary air that opens to a gas (that's the result of burner like CO2) that flows into from a patch and mixes with air.
How can i set a patch so that only gas flow into the domain of problem?

what are your advices or hints OpenFOAMers?
I only want a different gas enters from a patch into damain of air.
What things should be considered?

should I use two phase modeles or two species modeles?how?
all full helps or only little hints are appreciated!

Have a look at the combustion solvers. ReactingFoam with reactions turned off might fit for your purpose, I don't know the other ones.

thank you Robert
I hadn't thinked about combustion solvers.
I'll try it.

which gas or simple combination can better stand for burned gas from combustion in gas turbines?
A single gas is better so it suffice be only different from air.
is Co2 for example suitable for burned gas?

is reactingFoam compressible?which gas is more suitable for burnt gas out from gas turbine combustor?or how to model it?with a combination?
