Application of this solution in the fully-developed rotating pipe flow shows that the ASM suffers from two major defects; (a) the analytical solution gives rigid-body-rotation solution if the wall reflection influence is neglected* in contrary to measurements; (b) the symmetry behaviour of turbulence .

Then turbulent rotating pipe flow behaviors are investigated.

Status-monitoring of rotary diodes used in brushless exciting system;

A kind of swirling-rotating centrifugal equipment was developed,in which the centrifugal force field was intensified and the separation efficiency was improved remarkably.
