Рубрики: ФИЗИКА Кл.слова (ненормированные): CRITICAL CAVITATION POCKETS -- lENNARD-JONES FLUID Аннотация: Surface tension γ and effective radius R of critical cavitation pockets in a stretched Lennard-Jones fluid have been determined from the data on pocket formation work W *. The W * value has been calculated in terms of the stationary homogeneous nucleation theory from the results of molecular dynamics simulation of the parameters of cavitation process in a range of reduced temperatures T* = k B T/ɛ = 0.35–0.8. The calculated data have been approximated by the extended Tolman equation, which, in addition to linear correction (∼δ∞/R), takes into account the quadratic correction (∼l 2/R 2) for curvature to the surface tension of a critical pocket. It has been shown that parameter δ∞ is negative and amounts to a few tenths of an atom diameter, with the value of l being substantially dependent on temperature and reaching the diameter of a Lennard-Jones atom at the upper boundary of the considered temperature range. \\\\expert2\\nbo\\Colloid Journal\\2015, V.77, N2,119.pdf |
