Comparison of droplet dynamics in low-speed gaseous counterflow: Pressure-swirl and twin-fluid spra

Popis výsledku v původním jazyce

CO2 release into the atmosphere, responsible for global warming, can be reduced by spray scrubbing. Sprays are deployed to create an interfacial area for efficient gas-liquid contact in the spray column. The counter-flow of air interacts with the spray and causes droplet deceleration, momentum transfer, and air/droplet entrainment. Understanding the spray/air flow interaction can improve the pressure loss and droplet entrainment models, improve the estimation of entrained air velocity, and provide better insight into the spray column function. Twin-fluid effervescent atomizers, operated at injection pressure of 0.025 MPa and GLR ratios of 2.5 and 5%, were compared with hollow-cone and full-cone atomizers, operated at injection pressures of 0.05 and 0.2 MPa, under the counter-flow conditions. A vertical wind tunnel was used to simulate counter-flow conditions with an air flow velocity ranging from 0 to 1 m/s. The flow was seeded with water mist, generated by the ultrasonic atomizer, so that th
