In Aspen--tools--pure---property, the terms AVAIL CP CPCV CPTG CV DG DGPC DH DHPC DHVL DS G..... what do they all mean? ? ?
CP: Constant-pressure heat capacity of a pure component. CPCV: Specific heat capacity of a pure component (CP/CV). CV: Constant-volume heat capacity of a pure component. CPIG: Heat capacity of an ideal gas composed of a pure component. DG: Change in free energy of a pure component. DGPC: Pressure-corrected change in free energy of a pure component. DH: Change in enthalpy of a pure component. DHPC: Pressure-corrected change in enthalpy of a pure component. DHVL: Vaporization enthalpy of a pure component. DS: Entropy change of a pure component. G: Free energy of a pure component. GIG: Free energy of an ideal gas composed of a pure component. H: Enthalpy of a pure component. HIG: Enthalpy of an ideal gas composed of a pure component. PHI: Fugacity coefficient of a pure component. PHIPC: Poynting factor of a pure component. PL: Vapor pressure of a pure component. RHO: Density of a pure component. S: Entropy of a pure component. SIG: Entropy of an ideal gas composed of a pure component. V: Volume of a pure component. U: Internal energy of a pure component. SONVEL: Speed of sound (? ) K: Thermal conductivity; MU: Viscosity of the pure component; SIGMA: Surface tension of the pure component. The above are all my personal interpretations; please feel free to point out any errors
It is better to translate CPCV as adiabatic index (CP/CV), as it is used in the calculation of compressor power. The English term for DH is enthalpy departure; translating it as free energy change is acceptable, but what concept in thermodynamics does it correspond to? Remaining enthalpy? Or something else? I also looked up some information before; it seems that the term \"departure\" is not used to describe enthalpy changes. Let’s discuss this – the situations regarding DG and DS are similar to those of DH.
Reply 2# *aohaiyi8080 DH should be the enthalpy of formation, right?
I’ve learned it! This is very useful. I wonder if a more comprehensive version can be found
It’s explained in the status bar below; take a look
