Calculate characteristic length, Schmidt number and Peclet number for laminar non-reacting species?

    • kvehar

      Hi all,

      I am trying to calculate the Peclet number for mass transfer but I’m having trouble finding/calculating the variables.  I am running a laminar 2D axisymmetric model with non-reacting species diffusion. Does anyone know how I can calculate in CFD-Post the characteristic length for the grid/mesh/cell?  The Schmidt number? And/or the Peclet number? Is there a way to extract the characteristic length used to calculate the cell Reynolds number?

      Any help on the matter would be greatly appreciated, thank you!
