| Riassunto: | Title screen The results of two-dimensional (2D) mathematical modeling of binary collisions of liquid droplets in a gaseous medium using volume of fluid are presented. The computations were performed for water droplets in air. The model testing has shown acceptable agreement with the known experimental data. Here we also studied the impact of the following factors on water droplet collision regimes: droplet velocities and size ratios, Weber numbers, and temperature of liquid. The findings show the effect of angular and linear impact parameters as well as properties of the liquid on droplet disruption behavior. Droplet collision regime maps are presented showing the areas of maximum droplet atomization. The integral characteristics of secondary atomization are calculated for liquid droplets. |
