  2. Fluid Phase Equilibria - Wikipedia

    en.wikipedia.org/wiki/Fluid_Phase_Equilibria

    Fluid Phase Equilibria is a peer-reviewed scientific journal on physical chemistry and thermodynamics that is published by Elsevier.The articles deal with experimental, theoretical and applied research related to properties of pure components and mixtures, especially phase equilibria, caloric and transport properties of fluid and solid phases.

  3. Statistical associating fluid theory - Wikipedia

    en.wikipedia.org/wiki/Statistical_associating...

    Statistical associating fluid theory (SAFT) [1] [2] is a chemical theory, based on perturbation theory, that uses statistical thermodynamics to explain how complex fluids and fluid mixtures form associations through hydrogen bonds. [3] Widely used in industry and academia, it has become a standard approach for describing complex mixtures.

  4. Mie potential - Wikipedia

    en.wikipedia.org/wiki/Mie_potential

    The reduced phase diagram of a fluid consisting of particles interacting through a Mie potential with different values for the repulsive exponent (), all with the attractive exponent =. The cross indicates the critical point.

  5. Damköhler numbers - Wikipedia

    en.wikipedia.org/wiki/Damköhler_numbers

    The Karlovitz number (Ka) is related to the Damköhler number by Da = 1/Ka. In its most commonly used form, the first Damköhler number (Da I ) relates particles' characteristic residence time scale in a fluid region to the reaction timescale.

  6. Non-random two-liquid model - Wikipedia

    en.wikipedia.org/wiki/Non-random_two-liquid_model

    The NRTL parameter set to use depends on the kind of phase equilibrium (i.e. solid–liquid (SL), liquid–liquid (LL), vapor–liquid (VL)). In the case of the description of a vapor–liquid equilibria it is necessary to know which saturated vapor pressure of the pure components was used and whether the gas phase was treated as an ideal or a ...

  7. UNIQUAC - Wikipedia

    en.wikipedia.org/wiki/UNIQUAC

    In statistical thermodynamics, UNIQUAC (a portmanteau of universal quasichemical) is an activity coefficient model used in description of phase equilibria. [ 1 ] [ 2 ] The model is a so-called lattice model and has been derived from a first order approximation of interacting molecule surfaces.

  8. PSRK - Wikipedia

    en.wikipedia.org/wiki/PSRK

    PSRK (short for Predictive Soave–Redlich–Kwong) [1] is an estimation method for the calculation of phase equilibria of mixtures of chemical components. The original goal for the development of this method was to enable the estimation of properties of mixtures containing supercritical components.

  9. Thermodynamic modelling - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_modelling

    In case the development of a cubic model for a pure component is targeted, the purpose would be to replicate the specific volume behaviour of the fluid in terms of temperature and pressure. At a given temperature, any cubic functional form results in two separate roots which makes us capable of modelling the behaviour of both vapour and liquid ...
