Since the language of "transition and modulation" or "modulation and transition" seems obscure and the logical relation confusing, it is necessary to make a further disc.

Computational fluid dynamics (CFD) simulation of the internal flow in a labyrinth screw pump;

The theoretical study results and the experiment results on the principle,working characteristic of the labyrinth screw pump are summarized,and the method to determined its characteristic is presented.

Pumping mechanism of labyrinth screw pump(or seal),as yet incompletely understood,was analyzed based on numerical simulation of computational fluid dynamics(CFD) and pump performance experiments.
