hi, does anyone know what Del Giudice and Lemmon mean? I think it's about phase change. thanks for your help. nick

I did a search and came up with names of people. I also tried a universal translator and Del Giudice seems to be Italian. There was no translation for Lemmon.

Well I probably not much help but...

As far as I know, del Giudice and Lemmon came up with different ideas to calculate the specific heat cp (or to calculate cp*rho) from enthalpy and temperature for further use in the discretized Fourier equation in FVM.

Hope this is what you are looking for, Martin

thanks guys for your help In fact, I have seen these words in a book of Lusas. In material properties I have the choice for a parameter: 0 = phase change not required (default) 1 = Del Giudice 2 = Lemmon That's why I think Del Giudice means one phase change (solid-liquid) and Lemmon 2 phase changes (solid-liquid-gas). But I would like to be sure.
