摘要: Present work is focused on the numerical study of evaporation sessile liquid droplets top smooth solid substrates. The process a droplet has lots different applications both in industry and research area. This been under for many years, still it an actual problem, solution which can give answers some fundamental practical questions. Instantaneous distribution mass heat fluxes inside outside evaporating studied this using computer simulations. The deduced dependences instantaneous are applied self-consistent calculations time evolution droplets. proposed theory validated against available experimental data, shown good agreement. Evaporation surfactant experimentally. theory, two stages evaporation, fits data well. An additional stage, specific solutions, observed described. Mathematical modelling stage requires further adsorption its influence value receding contact angle. Numerical microdroplets conducted order to evaluate significance mechanisms (diffusive kinetic models evaporation) physical phenomena (Kelvin s equation, latent vaporization, thermal Marangoni convection, Stefan flow).
