the flow field of gas and liquid in a ф150mm rotating-stream-tray (rst) scrubber is simulated by using computational fluid dynamic (cfd) method. the simulation is based on the two-equation rng k-ε turbulence model, eulerian multiphase model, and a real-shape 3d model with a huge number of meshes. the simulation results include detailed information about velocity, pressure, volume fraction and so on. some features of the flow field are obtained: liquid is atomized in a thin annular zone; a high velocity air zone prevents water drops at the bottom from flying towards the wall; the pressure varies sharply at the end of blades and so on. the results will be helpful for structure optimization and engineering design.
