ThermoC—properties

pure fluids

• sublimation pressure curve
• melting pressure curve
• vapour pressure curve
• spinodal curve
• virial coefficients
• single-phase properties (for given pressure or molar volume): internal energy, enthalpy, entropy, compressibility, heat capacity, speed of sound, compression factor, …
• single-phase compression/expansion (isothermal, isenthalpic, adiabatic)
• adiabatic two-phase compression/expansion
• viscosity (from friction theory)
• surface tension (from friction theory or gradient theory)
• parameter fitting

mixtures

• fluid–fluid phase equilibria (vapour–liquid, liquid–liquid, gas–gas)
• solid–fluid phase equilibria (e.g., solid + supercritical fluid)
• isobaric-isenthalpic mixing and isobaric-isentropic mixing
• critical curves (all critical curves of a mixture in a single sweep)
• spinodal curves
• single-phase properties (for given pressure or molar volume): same as for pure fluids; in addition: excess properties
• transitiometer/DSC simulation (calculates heat during a temperature or pressure scan of a mixture with a fixed overall composition)
• single-phase compression/expansion (isothermal isenthalpic, adiabatic)
• two-phase adiabatic compression/expansion
• limiting diffusion coefficients of solutes in fluids (from friction theory)
• surface tension (from gradient theory)
• decomposition pressure of solids (hydrates, carbonates, …)
• parameter fitting
