N2 - Sustainable power production requirements call for extended ranges and more detailed accuracy in calculation of material properties in dynamic simulation of new designs of combustion power plants. Better thermal efficiency may be gained from increasing the steam temperatures to the over critical region. More detailed calculation in condensers requires also non-condensable gases to be considered in the steam and water circuits. Carbon capture and storage (CCS) concepts require that the flue gas circuits can include liquid carbon dioxide calculation. Oxy fuel concepts require separation of oxygen and extension of the material properties of air with liquid nitrogen and oxygen. Versatile use of dynamic simulation in design evaluation of such novel power production concepts require fast and accurate calculation of the material properties. The APROS thermal hydraulic solvers provide information on pressure, specific enthalpy, and mass fractions of mixture in each control volume as input for the material property calculations. The material properties calculated include the temperatures and void fractions of each control volume as well as the properties needed for each phase such as the mass fractions, densities, viscosities, specific heat coefficients and specific enthalpies. Extended range calculations of the material properties, as well as example applications, are presented.
