Experimental investigation of trajectory of motion of water drops in a flow of high-temperature gases

Research output: Contribution to journalArticlepeer-review


The conditions of slow-downs, hang-ups, and turns when drops of sprayed liquid are in an opposite flow of high-temperature gases (temperature was around 1100 K) using panoramic optical methods of particle image velocimetry, interferometric particle imaging, shadow photography, and Tema Automotive software have been dedicated. The distances passed by the drops until the full slowing down have been measured. Investigations have been carried out on the change in the characteristic dimension (conventional average radii) of drops in the range of 0.05–0.5 mm. The initial velocities of their motion and gases were varied in the range of 0.5–2.5 m/s and 0.5–5 m/s, respectively. The processes of water drops slowing down at the comparable initial velocities with gases in the conditions of intensive evaporation have been studied. The possible directions of improvements of chemical technologies of water and emulsions purification on its basis in the field of energy conservation using the results of experimental investigations carried out have been set.
