Induction thermal plasma simulation
 
Hi everybody,
I created my geometry in Gambit and I read the msh file with Fluent. Now I am going to solve it, but as I am a beginner in Fluent and especially Plasma simulation, I would like to know what I should do for the starting point. My question is more about how to define the plasma in Fluent and how to import data for plasma.is there any option or module for induction plasma in FLUENT 6.2?
P.S. the geometry consists of plasma torch (with five coil) followed by a tubular reactor. I have three inlets for the torch and one inlet for the reactor + one outlet.
thank you very much

I have not studied physics to the level of plasma, simply said I do not know if plasma can be treated as a continuum.
As you know, Fluent or other CFD programmes solve the Navier-Stokes equation which is developed as a result of considering fluids to follow the continuum hypothesis.

Now and after reading the following article
http://en.wikipedia.org/wiki/Plasma_(physics)

http://en.wikipedia.org/wiki/Plasma_%28physics%29

" The basic premise is that heating a gas dissociates its molecular bonds, rendering it into its constituent atoms. Further heating leads to ionization (a loss of electrons), turning it into a plasma: containing charged particles, positive ions and negative electrons.[1]"

I am a bit confused,
1- Can an equation of state be written to describe the flow of ionized particles
2- Can this flow of ionized particles be considered a continuum

If you know the answer to these two questions, I guess you can decide by yourself whether Fluent could be used or Not, and how

I hope someone with direct plasma experience could help
Good Luck

Thank you very much for your response,
I know that we can do it with Fluent and it has been already done. But I dont know how to do it. considering having all info, data, .. in hand how can I use Fluent for this problem? shoudl I write a code? or if I have the code how to use it with Fluent thats the Q.
Anyway, thank you again and hope someone could help
