Numerical Simulation of the Two-Phase Flow in Novel Combined Top and Corner Spray Degassing Tank for Aluminum Melt

Abstract:

The Eulerian two-fluid model incorporated with the multiple reference frame approach is adopted to predict the gas-liquid two-phase flow in the novel combined top and corner spray degassing tank for aluminum melt. The influence of different parameters, such as gas velocity or hole areas at the tank corners on the gas-liquid flow behavior is also investigated. Results show that little gas emerges near the wall of tank equipped with traditional rotating spray degasser. Using the combined top and corner spray degasser, the distribution of bubbles in the tank, especially near the tank wall, is improved significantly, which advantages the hydrogen removal. With the increasing gas velocity or hole areas at the tank corners, the width of ring zone with low gas volume fraction decreases, and thus enhances the effect of hydrogen removal.
