| Abstract: | The three-phase mockup experiments were processed respectively in three units with different draft tube structure,employing the quartz sand as the solid phase,the ambient air as the gas phase and tap water as the liquid phase.Successively used the draft tube with the diameter of 75mm and 60mm,and set the bottom gap height as 17mm and 30mm.The superficial velocity and the phase holdup under the same solid loading and initial liquid level,and the axial distribution of each phase at the same velocity were rese... |
