Temperature dependence of homogeneous nucleation rates for water: near equivalence of the empirical fit of Wölk and Strey, and the scaled nucleation model.

It is pointed out that the temperature fitting function of Wölk and Strey [J. Phys. Chem. 105, 11683 (2001)], recently shown to convert the Becker-Döring [Ann. Phys. (Leipzig) 24, 719 (1935)] nucleation rate into an expression in agreement with much of the experimental water nucleation rate data, also converts the Becker-Döring rate into a form nearly equivalent with the scaled nucleation rate ...

Scaled vapor-to-liquid nucleation in a Lennard-Jones system.

Scaling of the homogenous vapor-to-liquid nucleation rate, J, is observed in a model Lennard-Jones (LJ) system. The model uses Monte Carlo simulation-generated small cluster growth to decay rate constant ratios and the kinetic steady-state nucleation rate formalism to determine J at four temperatures below the LJ critical temperature, T{c}. When plotted vs the scaled supersaturation, lnS/[T{c}/...

Homogeneous nucleation of n-propanol, n-butanol, and n-pentanol in a supersonic nozzle.

We have measured the nucleation conditions of n-propanol, n-butanol, and n-pentanol in a supersonic Laval nozzle, and estimated that the maximum nucleation rate J is 5 x 10(16) cm(-3) s(-1) with an uncertainty factor of 2. Plotting the vapor pressures p(J(max) ) and temperatures T(J(max) ) corresponding to the maximum nucleation rate as ln(p) versus 1T, produces a series of well separated strai...

Efflorescence and ice nucleation in ammonium sulfate particles: Analysis of experimental results using scaled nucleation theory

Temperature-dependent efflorescence and ice nucleation results of ammonium sulfate aerosol obtained from flow tube studies are analyzed using a newly developed model based on scaled nucleation theory. The presented thermodynamic model defines trajectories of constant reduced nucleation barrier height as a function of temperature and yields simple analytic expressions for the liquid-solid nuclea...

Island-size distribution and capture numbers in three-dimensional nucleation: Comparison with mean-field behavior

The scaling of the monomer and island densities, island-size distribution sISDd, capture-number distribution sCNDd, and capture-zone distribution is studied as a function of the fraction of occupied sites scoveraged and ratio D /F of the monomer hopping rate D to the sper sited monomer creation rate F in a three-dimensional s3Dd point-island model of irreversible nucleation and island growth. O...
