The Pitzer-Lee-Kesler-Teja (PLKT) Strategy and Its Implementation by Meta-Computing Software

  • Ronald W. Missen University of Toronto


An extension of the corresponding states approach of Pitzer and of Lee and Kesler (Pitzer-Lee-Kesler (PLK) strategy) based on the work of Teja, et al., (PLKT strategy) provides a clear pedagogical setting for describing the underlying basis of the PLK strategy itself and also its extension to families of non-normal fluids.  Application of the strategy to two families of non-normal fluids is illustrated.  Furthermore, the PLKT implementation using meta-computing software provides a convenient tool to perform quantitatively accurate calculations while simultaneously emphasizing the thermodynamic problem structure.  Procedures and an example are given for illustration.
