RUSSIAN JOURNAL OF EARTH SCIENCES, VOL. 17, ES4001, doi:10.2205/2017ES000604, 2017 ![]() Figure 1. The efficiency of molecule condensation onto the particle surface vs the particle radius. Shown is the correction factor defined as the ratio of the particle condensation efficiency to its free-molecule value $\pi a^2v_T$. This dependence overlaps all regimes of the molecular motions, but in contrast to the Fuchs-Sutugin formula expresses $\beta(a)$ in terms of "observables", the molecular thermal velocity and the diffusivity (rather than the molecular mean free path). The correction factor remains almost constant up to $a=\rm10\,nm$. Copyright 2017 by the Geophysical Center RAS. Generated from LaTeX source by ELXpaper, v.1.5 software package. |
