Hello everyone,

I am currently using and modifying the wallHeatFlux utility in order to calculate other values, that are calculated from the heat flux. However, I am not quite sure how the utility calculates the heat flux... to be specific, I don't quite get this part:

Code:
surfaceScalarField heatFlux
        (
            fvc::interpolate
            (
                (
                    turbulence.valid()
                  ? turbulence->alphaEff()()
                  : thermo->alpha()
                )
            )*fvc::snGrad(h)
        );
What are alpha and h in the code?

I am using OpenFOAM 2.2.x

I would really appreciate it, if someone could assist me with this by pointing out which equation is being used here to calculate q.

Thanks in advance.
