The research of gas-liquid-solid flow in aeration tanks

Author(s): Yuxian Hu, Bing Chen, Yabing Guo

The characters of the gas-liquid-solid hydraulic flow in an aeration tank have enormous influence in treatment efficiency. The thesis modeled the three multi-phase flowcharacteristics in aeration tank, and combined with the measure of PIV. The simulation results agreed well with 3DPIV experiment results. The simulation results of flowstructure reveal the internal circulation of the water in the tank and the water with upward flow in the center region and downward flow near the wall.
