摘要: Droplet behavior in the wave-type flow channel is discussed, especially with the secondary
droplet generation due to impingement of droplets on the wall considered. A numerical
method is suggested to simulate the droplet behavior in the flow field. Calculations are
compared with experimental data on the pressure drop and separating efficiency. Good
agreement exists between the calculations and air-water experiments. The numerical method
developed gives a reasonable description of the droplet deposition and secondary droplet
generation, and it can be applied to predict the performance of wave-type vane separators.
