Modeling of micro- and nanodroplets

CZU: 53.091:532.614:539.61:544.7

Authors:

Baranov S.

Summary:

In this review, a formula that determines the curvature-dependent surface tension in a droplet with two phases has been discussed. Taking into account the dependence of the surface tension on the system size, nonlinear differential equations describing the droplet profile have been derived. It has been shown that, if the droplet size is not too large compared with the thickness of the surface layer (micro- or nanodroplets), the dependence of the surface tension on the curvature is extremely important.

În această lucrare se examinează formula care determină dependența tensiunii superficiale de curbură într-o picătură cu două faze. Ținând cont de dependența tensiunii superficiale de dimensiunile sistemelor, au fost obținute ecuațiile diferențiale neliniare care descriu profilul picăturii. S-a demonstrat că, atunci când dimensiunea picăturii nu este prea mare în comparație cu grosimea stratului de suprafață (micro- sau nanopicături), dependența tensiunii superficiale de curbură este foarte importantă.
