Specific heat USRSPH
 

Hello all...

I'm using the routine usrsph in cfx 4-4.

What's the difference between CP e CPBAR?

Thanks

Andrea

CP is the value used in the energy equation diffusion term.

CPBAR is used in converting temperatures to enthalpies and vice versa.

CPBAR should be calculated as the integral of CP from Tref to T, divided by (T-Tref). This gives the mean over the range from T to Tref. CP is the acual value at T.
