Abstract

Combined transfer processes in evaporating semitransparent liquid droplets and in their surrounding medium are investigated. The method of numerical research evaluates selective radiation absorption in droplets and its influence on the interaction of combined transfer processes. The influence of heat transfer peculiarities on the change of the evaporating droplet state is indicated. The regularities of the variation of heating and evaporating water, n-heptane and n-hexane droplet surface temperature are discussed. The results of the numerical research are compared to the results of experimental studies.
