I have a couple of questions about writing a transport model.
I would like to model mixing with a viscosity which is a function of the volume fraction gamma. I think the best way to go about this would be to create a new transportModel. I looked at the header and c file for the CrossPowerLaw model, but am still a bit confused.
Can I introduce gamma using the syntax
const volScalarField& gamma
in the constructor? I would then need a way to call the local gamma to calculate the viscosity, in a way similar to the strainRate() function?
My end goal is to be able to specify coeficients for a polynomial in gamma n0,n1,n2,... so that
nu = n0+n1*gamma+n2*pow(gamma,2)+....
Can I introduce the set of n's the same way the nu_0 and etc are introduced in the CrossPowerLaw header and C file?
Am I thinking about this correctly? Have I missed some documentation that already covers this?
