PHOENICS 3.5 temperature calculation

November 10, 2003, 07:41

The definition for Cp has been changed in PHOENICS 3.5, where internally it is defined by PHOENICS where T=(h-h_base)/Cp. By using our previous equation (prior to version 3.5) which is given by -(k/Cp).grad(h) for conduction term, we defined only the value of the term (k/Cp), now in PHOENICS 3.5, how can we calculate this k value? Do we need to calculate this value?

Thank you for any volunteer trying to help me.

Jas,

I know very little about conduction but it seems to me that k is a "coefficient of conduction", similar to e.g. ENUT for turbulent diffusion. If so, is not k specific to the material in which the conduction is taking place? Is it not something you pick out of tables of material properties?

Correct me if I've misunderstood your question.
