Improving traditional process aerating evenness and controlling the centrifugal inertia effect of tiny vortex of multiphase would contribute to the mass transfer and the alternative of interface,then the efficiency of biochemical reaction was improved and the process was shortened observably.

The conventional flocculation tank was reconstructed according to the tiny vortex theory, and the result showed that the modified tank is able to reduce the turbidity of settled water and improve removal efficiency of COD _(Mn) and algae.

Applicability of turbulence models in numerical simulation of vortex flow in pump sump;

Study on characteristics of vortexes in front of intakes of Three Gorges Underground Power Station;

Research on electromagnetic vortex flowmeter;

The eddy,by which the utilization rate of assembly unit is promoted,is the critical symbol of the turbulent transportation.

The large eddy simulation(LES) method was used to simulate the steady divergent pressure flows.

It shows through the model test that sucking eddy,shock wave and energy dissipation exist in the original layout plan.

It is concluded that the erosion is caused by vortex flow.

But in the semi-spiral suction chamber,swirls occur beside the tongue and sealed block a.

It needs the initial value of eddy to discuss Bose-Einstein Condensate by a numerial value method,and various initial values of eddy for different parameters.
