Nucleation stage in supersaturated vapor with inhomogeneities due to nonstationary diffusion onto growing droplets

, 2013
An analytical description of nucleation stage in a supersaturated vapor with instantly created supersaturation is given with taking into account the vapor concentration inhomogeneities arising as a result of depletion due to non-stationary diffusion onto
