reactingParcelFoam: particle heating
 

Hallo,

I am trying to figure out how paticle heating is implemented in reactingParcelFoam when using the Ranz Marshall heat transfer model. As I could figure out in RanzMarshall.C OpenFOAM uses the Nusselt number

Nu=2+0.6*sqrt(Re)*cbrt(Pr)

However, I cannot find the differential equation describing the heat transfer between fluid and lagrangian particle. I assume something like

mparticle*Cpparticle*dTparticle/dt=Nu*lambda/dparticle*Ap*(Tfluid-Tparticle)

should be implemented.

Can anybody give me a hint were the heat transfer between fluid and particle is implemented in reactingParcelFoam?
