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