Hello everybody,

I would to simulate a (steady) laminar flame using a detailed kinetic scheme, but it seems to me that there is not a standard solver available for this case.
I had a look to the simpleFoam and icoFoam solvers but I don't know if it is possible (and easy) to adapt them to take into account non-uniform gas density.
Is there anybody who already solved this kind of problem? Do you have any suggestions?

Thank you,
Danilo

Hi,

I think 'reactingFoam' is suitable for your case.

Hi,

probably this is the best choice, but I have to modify the solver because I need a laminar code; in particular I don't need any model to close the reaction rates.
I will try to eliminate the equations for epsilon and kappa, using at the same time the reaction rates without the PASR correction. Does it make sense?

Thank you

Hi everybody,

I need to calculate the reaction rates for every species included in the kinetic scheme (I'm using the reactingFoam solver) but I didnt understand the 'solve' function in the 'chemistryModel' object.
Is this function used for solving an ODE system? Why? In my case I need just the local reaction rates as predicted by the Arrhenius law (the flame is laminar); which function I have to use to obtain this kind of information?

Thank you,
Danilo
