EXPERIMENTAL STUDY ON EVAPORATION BEHAVIOR OF WATER DROPLET WITH METALLIC INCLUSION

Abstract

We perform the experimental research on particularities of phase changes of heterogeneous droplets based on water with single metallic inclusions. We applied the metals and alloys which are typical of power engineering. Moreover, the lifetimes of 5-15 µl water droplets were determined. We also established the estimated proportion of phase change energies (vaporization) as well as those absorbed by water and metallic inclusions. Finally, we formulated the recommendations how to use the suspensions of water with metallic inclusions in cooling systems of hot surfaces of power engineering equipment, as well as high-temperature gas-vapor flows.
