“…The results of these experiments (in particular, [1]) can be used for pre dicting typical conditions for deceleration of drops in the counter flow of gases and their subsequent entrain ment in the direction opposite to the initial motion. These processes are important for various technologies using gases at high, moderate, and low temperatures (in particular, [11][12][13][14][15][16][17]). However, experimental results [1][2][3] have not been generalized in the form of criterion expressions characterizing the conditions of deceleration and possible subsequent entrainment of drops by a high temperature gas flow.…”

On the basis of the results of experimental investigation of motion of water drops (from 50 to 500 μm in size) through high temperature (about 1100 K) gases, we determine the conditions (in the form of criterion expressions) for deceleration of these drops and their entrainment by gases moving in the opposite direction. We introduce the Reynolds numbers of the dispersed and carrier phases as the characteristics of the given process. Optical particle image velocimetry (PIV) and interferometric particle imaging (IPI) methods, cross correlation video complex with a pulsed laser, and a high speed (10 5 frames per second) video camera are used. The initial velocities of the counter motion of water drops and gases are varied in ranges typical of many applications (0.5-5.0 and 0.5-2.5 m/s, respectively). The possibility of predictive simulation of drop deceleration conditions based in a relatively simple model of interaction of solitary elements of the disperse phase and high temperature gases is demonstrated.
