Ideal Gas Mixture, non reacting
I'm a newbie in OOP programming and numerical modelling. I'm trying to simulate a gas mixture flowing in a complex 3D geometry, but I don't know how to write my thermophysical model. I tried to learn something from the forum but I didn't find a clear response.
I have a gas mixture of: 90% Helium, 9% N2 and 1% Xenon. I would like to use the ideal gas law to calculate rho during the numerical simulation.
I thought something like:
Thanks in advance
About my previous question,
I send you in attachment my ThermophysicalProperties file. I guess should be right, but my doubt is that in this way I have an homogeneous mixture. And this is not what I want, because I have inhomogenoeus mix.
Where can I define my rho... something like rho=0.9*rho_He+0.09*rho_N2+0.01*rho_Xe, or maybe define the partial pressure?
I look forward to hearing you
have a look at the combustion examples there you will find how to define mass or volume fractions.
I have a similar problem in finding a thermophysical model for the simulation of an inert mixture of gases. All I want is to use temperature dependent thermophysical properties of a gas mixture where I can arbitrarily define its composition.
I am so far as to believe that this must be either trivial or very hard, because all I can find concerning this topic are threads like this, where the answer is rather unsatisfying.
Do I understand correctly that the pureMixture model is not capable of treating mixtures the way I want?
Looking at the combustion tutorials did not help me very much to be honest, because those are dealing with chemical reactions - or is it a common workaround to use those models without chemical reaction?
thanks in advance, best regards
im working on a simliar problem i need a mixture of different gases. But the puremixture is not supporting that.
Im trying now to implement the combustionthermodynamics in rhoCentralFoam.
has anyone experience with that?
i also want to model a compound of gases without reaction.as well as question that propounded i have a question that
Which combination should i choose for gases coming out from a typical gas turbine combustion chamber? I want to analyze this compound to another device without any combustion or reaction.
