Hi Read this paper -...

Hi

Read this paper - http://powerlab.fsb.hr/ped/kturbo/Openfoam/docs/FabianPengKarrholmPhD2008.pdf

It has details on how reaction source term is modeled in OF.

As I said in previous post,...

My solver is running for around 500 time steps beginning with 0.

It goes to a time of around 2e-6 and then I get the above error that T has exceeded 5000 K limit to become ~5200K.

I have also...

No I don't use the standard version of reactingFOAM.

I have modified it for supersonic combustion and hence the energy equation has been modified to solve for supersonic flows.

Actually I have...

Hi Valerio,

Correct me if I am wrong but I think that if assumption of Le=1 is there then we should have alpha instead of mu in the species equation.

In hs-equ. also for Le=1 they have used...

Hi,
Do you mean that at higher velocities when you did the simulation with unit Lewis No., you again got temperature inconsistencies?

Are you getting agreeable results with combustion(reaction)...

Hi kaka22,

How much is your maximum temperature?

If its only a little more, it might be due to sudden compression of gas in some regions of your domain.

If its considerably more then I don't...
