Master crossover behavior of parachor correlations for one-component fluids

Abstract

The master asymptotic behavior of the usual parachor correlations, expressing surface tension $\sigma$ as a power law of the density difference ${\rho }_L-{\rho }_V$ 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 $({\beta }_c{)}^{-1}$, ${\alpha }_c$, $Z_c$ and $Y_c$, 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.
