Abstract
In our previous research, we mentioned about mixing of small solid sedimentary particles using a swirl motion of a bubbling jet. The lifting behaviors of the particles were classified into two types depending on the aspect ratio (LN/D) of the bath, where LN the nozzle depth and D the bath diameter. The two types of lifting behaviors were closely associated with the isolated vortex appearing for LN/D=0.2–0.4 and twin vortices appearing for LN/D=0.5–0.8. These vortices were similar to the tornado. In this study, empirical equations are proposed for the volume of sedimentary particles lifted up by a swirl motion of a bubbling jet as functions of the gas flow rate, vessel diameter, bath depth, and the physical properties of fluids.
