Hi All,

I have been trying to create a model for multi-species turbulent reacting flow (not Combustion). After going through the threads, I am finding it difficult to understand some of the key issues which I am listing below:

1) What *.H files are required ?

I have included the following:
i) multiComponentMixture.H
ii) UEqn.H, pEqn.H, hEqn.H,YEqn.H
iii)turbulenceModel.H, transportModel.H
iv) chemistry.H, reactingMixture.H,readChemistryProperties.H

2) I have modified the reactingFoam.C file to remove/add the required files to convert into a Multi-Component-Reacting file --- will this change work ?

3) Since I am using a incompressible turbulence model, what changes are required to convert the simpleFoam into a multispecies reacting flow model ? What header files are to be included ?

4) In the transportProperties and thermophysicalProperties input files, how do I include rho and Cp as a function of the species mass-fraction?

Pls let me know as soon as possible. It would be great if there are some examples or tutorials.

Thanks in advance.

Hi Sanjib,

can you tell us more about your case?

- You have a certain number of species, a mixture of reacting gas/liquid?
- How do you define the reactions?

I was wondering why "reactingFoam" isn't suitable for you. Is it because of the chemistry library in OpenFOAM?
