Equations of State

We are building clusters for higher end binary mixture modeling work. A cluster comprises of a series of thermodynamic property models we create, or equations of state (EOS) for a given binary fluid mixture.

Previously completed clusters contain a given fluid mixed with the following: Oxygen, Methane, Ammonia, Water, Ethylene, Ethane, Hydrogen Sulfide, Argon, Propylene, Carbon Dioxide, Propane, Acetone, Butane and Isobutane, Pentane and Isopentane, Benzene, Cyclohexane, Hexane, Toluene, Heptane, Octane, Nonane, Nitrogen, and Decane. It is important to note that a thermodynamic property model can only being created for binary fluid mixtures that contain experimental measurements. Therefore, not all clusters may be comprised of all the above fluid mixtures.

A series of clusters have been completed with the following fluids: Methanol, Methylcyclohexane, Ethanol, Ethylene, Propylene, Benzene, and Toluene.

Currently in review is a cluster of 24 EOS of methanol binary mixtures (See Publications and Patents). More journal articles will follow encompassing the completed clusters.

Currently we are comprising a series of clusters containing the following cryogenic fluids: Helium, Hydrogen, Hydrogen Deuteride, Deuterium, Tritium, Methane, Neon, Nitrogen, Carbon Dioxide, Oxygen, Ammonia, and Argon. Our goal is to create a cluster of all possible binary combinations of the cryogenic fluids stated.

The following combinations are already underway: Helium/Hydrogen, Helium/Methane, Helium/Neon, Helium/Nitrogen, Helium/Carbon Dioxide, Helium/Argon, Hydrogen/Methane, Hydrogen/Neon, Hydrogen/Nitrogen, Hydrogen/Oxygen, Hydrogen/Ammonia, and Hydrogen/Argon.

 

Things to look for in upcoming posts:

  • In-depth instructions and coding on how to implement use an EOS. This will be done using Engineering Equation Solver (EES) software.
  • Research progress updates for the methanol journal article under review
  • Cryogenic EOS development updates
