rhoReactingFoam
 
Hello,

Since there is no tutorial for rhoReactingFoam, I tried to develop a tutorial case. However I was not successful. It seems that this solver still uses CHEMKIN style for chemistry input.

I tried with foam.inp and foam.dat from another case and it did not work.

Is there some way to make this solver work? I would be thankful if a tutorial case could be put in the OF-1.6.x.

Thanks,
Rachel

We have uploaded a tutorial for reactingFoam in OpenFOAM-1.6.x:

tutorials/combustion/reactingFoam/ras/counterFlowFlame2D

this could also be altered to run with rhoReactingFoam.

rhoReactingFoam tutorial,
 
Dear all,

Would you please confrim following changes, which I made to keep "counterFlowFlame2D" working under "rhoReactingFoam"? (but I am not sure it should be the same for every other case)

1- In chemistryProperties; rhoChemistryModel ODEChemsitryModel<gasThermoPhysics>;
2- In ThermophysicalProperties; thermoType hRhoMixtureThermo<reactingMixture<gasThermoPhysics >>;
3- In fvSolution;
pFinal
{
solver PCG;
preconditioner DILU;
tolerance 1e-7;
reTol 0;
}

What kind of problems this solver is basically designed to solve?

Thank you in advance,
Hamed

Dear all,
I have to simulate the effects of a Boiling Liquid Expanding Vapor Explosion (BLEVE) on a 3D environment. After being released, the gas may burn. The overpressure due to the exploding evaporation (and the fire ball) must be simulated. Is this "rhoReactingFoam" solver appropriate to do such a calculation ? I found no documentation about this solver and I encountered difficulties to make it run on a 3D mesh for a simple case. Any informations about documentations (or tutorial) would be very appreciated.
I thank you for your attention,
JB

Hi, friend. could you tell me how to alter the reactingFoam to rhoReactingFoam tutorial. Do you know what kind of combustion model is used in rhoReactingFoam? also PaSR?
