RhoCentralFoam-MultiSpecies-NonReacting
 
Hi,

I need to adapt rhocentralFoam to do mulitspecies non reacting simulation. Basically, at the inlet, I would like to inject 2-3 types of gases.

Can anyone gives me a suggestion of how to go about this matter?

The rhoCentralFoam.C looks much more complicated compared to other solvers and hence, I dont have much clue to change the codes so that I can take in multispecies/gases I need to inject in.

Thank you very much.

Hi Azanulbizar,
Have you solved this problem?
So is it possible to introduce 2-3 non-reacting gases mixture in rhoCentralFoam?
I am working on delaval nozzle and I want to introduce them at nozzle inlet.

Thanks in advance!

Hi,
I have published a couple of years ago a paper on a new OpenFOAM solver we have developed for a two-phase model using a central scheme approach similar to that used in rhoCetralFoam:

La Spina, G. & de' Michieli Vitturi, M. High-Resolution Finite Volume Central Schemes for a Compressible Two-Phase Model SIAM Journal on Scientific Computing, SIAM, 2012, 34, 861-880

In a more recent work we have also introduced mass transfer in the model.
If you are interested you can send an email to the first author asking for the code.

Ciao

P.S. I have attached a figure from one of the papers comparing the results of a simulation with those of a lab experiments for the interaction of a shock wave with a cylindrical bubble.

Thanks demichie for your reply. I have gone through the paper but it's for 2 phase flow. How do I edit rhoCentralFoam.C to simlulate multi-species in the gaseous phase? Thanks in advance!
