Hello All,
I am wondering if there is a possibility to run conjugate heat transfer such as chtMultiRegionFoam using a real gas Equation of State such as Peng–Robinson.


Many thanks in advance.

Very keen to know if this is possible at all, adapting Peng-Robinson into chtmultiRegionFoam

Yes, I used Peng-Robinson in a simulation with chtMultiRegionFoam and it worked.

Which version are you working with? Can you provide more details of the thermophysical file ?

Thank you

Hi,

As long as Peng-Robinson is implemented in the thermophysical models, it should be possible to use it with chtMultiRegionFoam : https://www.openfoam.com/documentati...onOfState.html

Searching the forum might also help to find answers: Usage of PengRobinsonGas

I hope this helps,
Yann

I used the following thernophysical file

PHP Code:

and following error came up

Update;

I tried to update src/thermophysicalModel/basic/rhoThermo/rhoThermos.C

as

PHP Code:
makeThermos
(
    
rhoThermo,
    
heRhoThermo,
    
pureMixture,
    
constTransport,
    
sensibleEnthalpy,
    
hConstThermo,
    
PengRobinsonGas,
    
specie
); 
But still the error is

--> FOAM FATAL IO ERROR: (openfoam-2206)
Unknown rhoReactionThermo type

Valid rhoReactionThermo types :

70
(
heRhoThermo<homogeneousMixture<const<hConst<PengRo binsonGas<specie>>,sensibleEnthalpy>>>
heRhoThermo<homogeneousMixture<const<hConst<incomp ressiblePerfectGas<specie>>,sensibleEnthalpy>>>
heRhoThermo<homo..............

Thank you for any help.

Hi Dasith,

OK I understand, this error usually happens when trying to use an invalid thermo package: it's not possible to use any combination of models (thermo type, transport, thermo, equationOfState, etc)

After a quick search I found this thread: PengRobinsonGas crashing with high pressures on fine mesh
where Peng-Robinson is used with this thermo package:

Code:
thermoType
{
    type            hePsiThermo;
    mixture         pureMixture;
    transport       polynomial;
    thermo          hPolynomial;
    equationOfState PengRobinsonGas;
    specie          specie;
    energy          sensibleEnthalpy;
}
So I guess you have 2 options: using a suitable thermo package to be able to use Peng-Robinson, which will require to adapt your case setup (no idea if this will be compatible with chtMultiRegionFoam) or compile your own thermo package to be able to use it as you wish. But it might require to adjust a bunch of stuff in the code and you need to be sure your changes make sense, physically speaking.

Hi All,

Thank you for all the ideas, finally figure it out.

OpenFoam Version 10 facilitates PengRobinsonGas model with chtMultiRegionFoam solver, my model works fine now.

Cheers,
Dasith

Hi Dasith,

Thanks for your feedback.
Would you mind sharing your thermophysicalProperties setup? It could help other people who want to use PengRobinsonGas model.

Thanks,
Yann
