Master crossover behavior of parachor correlations for one-component fluids

Statistical Mechanics 2007-12-11 v1

Abstract

The master asymptotic behavior of the usual parachor correlations, expressing surface tension σ\sigma as a power law of the density difference ρLρV\rho_{L}-\rho_{V} between coexisting liquid and vapor, is analyzed for a series of pure compounds close to their liquid-vapor critical point, using only four critical parameters (βc)1(\beta_{c})^{-1}, αc\alpha_{c}, ZcZ_{c} and YcY_{c}, for each fluid. ... The main consequences of these theoretical estimations are discussed in the light of engineering applications and process simulations where parachor correlations constitute one of the most practical method for estimating surface tension from density and capillary rise measurements.
