COCO - CAPE-OPEN to CAPE-OPEN simulation environment

Internal Energy

Internal Energy, for all phases, is calculated from:

U = H - P V

for which enthalpy and volume need to be available.

For the overall phase, internal energy can be calculated by summation over the existing phases, taking phase fraction into account.

If TEA's internal calculation routines for enthalpy and volume are used, the internal energy will not include the formation terms (heat of formation).
