The above-mentioned gas–liquid–soli

The above-mentioned gas–liquid–solid systems are the cases
of heavier particles (settling in liquid phase) suspended in liquids.
The mixing of gas–liquid floating particles is another branch
of three-phase systems and is also encountered in process Consequently, liquid-mixing is of vital importance for the reliable
design and scale-up of gas–liquid–liquid stirred reactors. In
addition, the mixing time information is a very useful indicator
for fluid dynamic behavior as the fluid dynamic characteristic of
gas–liquid–liquid systems is difficult to be determined directly for
its complexity.
