Hi All,

I am reading the file of LaEuScalarTemp.C and would like to study how to calculate the heat convection in the coupling work. I am not sure the following line is correct or not:

Rep = 2*rs*magUr/nuf;
Pr = Cp_*nuf*rho_[cellI]/lambda_;

The CFDEM version I use is CFDEMcoupling-PUBLIC-2.2.x.

I think in the Li and Mason's paper (2000, 2002)
Rep = rho_[cellI]*2*rs*magUr/nuf;
and
Pr =Cp_*nuf/lambda_;

the density items should be with particle Reynolds numbers.

Thanks!

Kun

Hi Kun,
Li & Mason refer to the dynamic viscosity, LaEuScalarTemp is calling the kinematic viscosity. They're equivalent the way it's written in the code.
