Steady state Multi species non-reactive model
 
hi,
I am new to OpenFOAM. I want to develop steady state multi species non reactive model. How to go about it?

Do I need to modify the simpleFoam code to introduce the species equation? If yes, how to do it? Correct me, if I am wrong.

Is there any otherway to do this?

Hello,

I guess it would be easier the way round. Start with reactingFoam and switch off the chemistry source terms. Then you can make it a steady state solver. Maybe buoyantSimpleFoam is also a good start because it already deals with temperature.

Regards Markus.

Hi Markus,

I will try your suggestions. I will get back to you if I face any difficulty. Have a good day!!!:)

Thanks

Steady state Multi species non-reactive model
 
Hi Hrushi,

Were you able to implement a steady state solver steady state multi species non reactive model. I am working on the same thing and was using the Particle-tracking LTSReactingParcelFoam with everything turned off, but my pressure was blowing up. I also used porousExplicitSourceReactingParcelFoam transient solver, but my rho and temperature was not changing. I was thinking if a combustion solver will be better with the reaction turned off.

reactingFoam to steadyState
 
Hi Hrushi,

As per the previous question from Kiyya,

Where you able to development and implement reactingFoam as a steady state solver?

In addition to switching off chemistry (chemistryProperties) and combustion (combustionProperties) what other steps must be taken in order to adapt the reactingFoam solver into a steadyState solver?

Kind regards,

James
