Abstract

Evaporation of a water-methanol solution droplet is experimentally studied. This process is mathematically modeled. Based on the results of a comparative analysis of the results of physical and numerical studies, the parameters of the evaporation of a water-methanol solution droplet are determined for the purpose of using its combustion in mathematical modeling. The results of numerical studies of the combustion of a gas flame with the injection of the water-methanol solution droplets into it in an industrial plant are presented. These results satisfactorily correlate with experimental data.
