Analysis on turbulent flow in impeller of centrifugal pump;

Analysis of turbulent flow in the impeller of bittern transfer pump;

Discretization algebraic equation of nonaxisymmetry three dimension turbulent flow;

In order to improve the separation mechanism, LDV (Laser Doppler Velocimetry) was used to measure the characteristics of gas turbulence flow in the cyclone tube.

Experiments show that the formation of Taylor bubble in gas\|liquid two\|phase flow is due to the intensive congregation and amalgamation of small bubbles driven by void fraction waves and that the highly turbulent flow is able to restrain this formation.
