Thermomixer

Calculator for multicomponent and multiphase compounds.

Allows you to calculate thermodynamic properties for clean components or for mixtures of arbitrary composition:
- Temperature, Pressure, Volume, Vapour Fraction, Enthalpy, Entropy by Peng-Robinson (1975) EOS
- The equilibrium compositions of vapour and liquid phases
- Liquid density by Yen-Woods eq.
- Heat of evaporation (EOS)
- Cp – heat capacity isobaric (EOS)
- Cv – heat capacity isochoric (EOS)
- sonic speed (EOS)
- adiabatic coefficient (EOS)
Thermophysical properties:
- Thermal conductivity (Stiel-Thodost eq. for gases, polynomial for liquid)
- Viscosity (Jossi-Stiel-Thodost eq. for gases, polynomial for liquid)
You can calculate thermodynamic characteristics of some apparatus:
- Heat exchanger
- Isoenthalpic valve
- Polytropic compressor
- Polytropic expander

CO2 freezing utility (you can define temperature of freezing or concentration of freezing).

Extensive macro language (Description: http://sggdev.blogspot.com/2012/02/thermodroid-hd-macro-language.html, Samples: http://sggdev.blogspot.com/2012/03/thermodroid-hd-macro-calculation-of.html).
(only for clear components now)
