All components are based on thermodynamic property and state calculations. Thermolib computes enthalpy, entropy, free Gibbs enthalpy and heat capacity using the well documented JANAF thermophysical tables in the NASA polynomial representation. Condensable gases, liquids and their mixtures are adequately modeled.
The thermophysical data for calculating the properties of the various species and their mixtures, including the vapor fractions, are provided through an extendable and expandable species database. Furthermore, Thermolib provides blocks for convenient conversions of state variables to other state variables.

Thermolib contains different blocks for modeling chemical reactions. The user can choose between a chemical reactor with equilibrium chemistry or a reactor with irreversible overall reaction and prescribed conversion. Reactions
can be configured to be adiabatic or non-adiabatic. The user can modify the chemical reactions via parameter masks.

Thermolib provides predefined blocks for modeling reformer and water gas shift reactions, combustion, preferential oxidation reactor etc.
