Abstract

We report the executed experimental investigation of initial sizes and velocities of water droplets movement influence on integral characteristics of its transfer (motion trajectories, velocities, sizes, relative concentration) through high-temperature (more than 1000 K) gas area. It was used the optical methods of two-phase gas-vapor-droplet mixtures diagnostics ("Particle Image Velocimetry" and "Interferometric Particle Imaging"). The limiting values of gas velocities, velocities and sizes of water droplets have been established when the complete droplet evaporation in high-temperature gas mixture is possible. Several modes of droplet motion through the gas flow in intensive evaporation conditions have been singled out and the dependences have been received which allowed to predict these modes.
