Considerable attention has been devoted in the past to the determination of the minimum agitation speed, N HQ , required to just suspend solids in mechanically stirred tanks. However, the effect of the impeller off-bottom clearance has not been well established, particularly when the impeller is pos
## Abstract A computational fluid dynamics (CFD) model is adopted to simulate the turbulent immiscible liquidβliquid flow in a stirred vessel based on a twoβfluid model with a __k__βΟ΅β__A__~P~ turbulence model. An improved innerβouter iterative procedure is adopted to deal with the impeller rotatio
