Reference Quality Equation of State (EOS) Fitting
We are building clusters for higher end binary mixture modeling work. A cluster comprises of a series of thermodynamic property models, or equations of state (EOS) for a given binary fluid mixture. At the HYPER Lab we are able to create binary fluid mixture models, pure fluid mixture models, and have the capability to create experimental measurements with a Rubotherm, which is currently retrofitted for cryogenic service.
Previously completed clusters for binary fluid mixtures 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 be 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.
As of date, Deuterium and Iso-octane are the only completed pure fluids. For the Deuterium Journal Article please see the Publications and Patents page or click here to be directed to the JPCRD website.
Currently we are comprising a series of clusters of binary fluid mixtures 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.
