Statistical Surface Thermodynamics of Liquid Mixtures

Thermodynamics of Liquid 'he- " He Mixtures

The osmotic pressure of 3He-4He solutions is shown to follow in a natural way from the separation of the specific heat in a quasiparticle contribution and a 4He-contribution. Expressions for important thermodynamic properties such as the chemical potentials, the internal energy, the entropy, specific heat, osmotic pressure, etc. are given for the case the quasiparticle gas can be treated as a n...

Thermodynamics of Liquid (Xenon + Methane) Mixtures

A new apparatus for the study of vapor-liquid or vapor-liquid-liquid equilibrium has been assembled. The apparatus, based on a static and analytical method, can perform measurements at temperatures from 185 to 320 K and pressures up to 8 MPa. The equilibrium vapor pressures of (xenon + methane) binary mixtures have been measured at seven temperatures, from 189.78 to 273.18 K, and at pressures u...

Statistical Thermodynamics of Material Transport in Non-Isothermal Mixtures

The Liquid Density of Complex Liquid Mixtures

A second virial coefficient correlation suitable for two different temperatures ranges, (T*)-2£180 and (T*)-2>180, where T* is RT/DHvap is presented. The equation of state can be calculated for different, complicated non-polar, and slightly polar liquid mixtures at any temperature over the range from Ttp to T<su...

Surface Tension Prediction for Liquid Mixtures

Recently Escobedo and Mansoori (AIChE J. 42(5): 1425, 1996) proposed a new expression, originally derived from statistical mechanics, for the surface tension prediction of pure fluids. In this report, the same theory is extended to the case of mixtures of organic liquids with the following expression, σm = [(1-Tr,m) Tr,m exp (0.30066/Tr,m + 0.86442 Tr,m) (P 0,m ρL,m P 0,m ρv,m)] 4 P0,m = { ΣiΣj...
