The processes of retardation and subsequent entrainment of droplets of size 50–500 μm of a polydisperse water flow by high-temperature (about 1100 K) gases are investigated by means of the "Particle Image Velocimetry" and "Interferometric Particle Imaging" optical methods, cross-correlation cameras, and pulsed lasers. The initial velocities of motion of water droplets and gases varied within the ranges 0.5–5 m/s and 0.5–2.5 m/s. The limiting relationships between the initial velocities and dimensions of droplets at which the conditions for the entrainment of them by a gas countercurrent flow are implemented established. A dimensionless criterion for prognostic evaluation of the retardation conditions and of the subsequent entrainment of water droplets by high-temperature gases under analyzed conditions is introduced into consideration.
