reactingFoam output 'a'

lollo15 · April 14, 2021, 09:44

Hello everyone!

I'm a rookie with reacting flows and now I'm using reactingFoam.
I'm using 'EDCv2005' as combustion model and a an ode/standard chemistry combustion solver like the tutorial SandiaD_LTS. Also the themophysical file is set as the tutorial file.

Between the output there is a field called ''a'', i tried to look for the the file where the filed 'a' is defined but I failed.
Does everyone know how it's defined or where ?

Thanks in advance.

My first guess would be from the radiation model (which is used in the sandia tutorial), where "a" designates an absorption coeff. The following snippet is from absorptionEmissionModel.H :

Code:

                //- Absorption coefficient (net)
                virtual tmp<volScalarField> a(const label bandI = 0) const

I've not tracked down if/where this may be written, but it seems plausible at least. If anyone has a better idea, please correct me.
