On Marangoni instability during desorption accompanied by evaporation

摘要

It has been proved theoretically that the combined process of desorption and evaporation can take place both in stablke and unstable regimes. The conditions of hydrodynamic instabiity of the process have been determined. It has been shown that carbon dioxide desorption from water comboined with its evaporation into dry nitogen takes place in a hydroidynamically unstable regime. Numerical solution of the spectral problem of this process for small perturbations has been performed. The time during which the process passes into an unstable regime has been estimated.
