Regularities in Evaporation and Carryover of Polydisperse Water Flow Droplets During Motion Through High-Temperature Gases

  • Published:
Chemical and Petroleum Engineering Aims and scope

The macroscopic regularities of the motion of water droplets (initial size 50–500 μm) moving through a counter-flowing high-temperature gas at about 1100 K were investigated using panoramic tracer visualization optical methods (Particle Image Velocimetry and Interferometric Particle Imaging). Characteristic velocities of water droplet evaporation, as well as conditions for their retardation and subsequent carryover by high-temperature gases, were determined. The limiting initial velocities and sizes of droplets for which the conditions of retardation and carryover are implemented were established. Recommendations for improvement of the effectiveness of thermal (high-temperature) water cleaning were formulated.
