Abstract: The turbulence structure control by adding component parts similar to the large eddy break up device and riblets in the hydrocyclone was investigated by studying the characteristics of the turbulent pressure field,and the relationship between turbulence structure variation and energy consumption reduction was also studied. The results showed that all the time-averaged characteristics of turbulenyt pressure distribution,pressure fluctuation,relative pressure fluctuation and the probability density distribution characteristics of fluctuating pressure in the hydrocyclone were controlled effectively by adding a winged core and adopting a spiral type cone,and the energy consunmption in the hydrocyclone separation process was reduced remarkably.The winged core is very effective in controlling the trubulence structure and reduceing the energy consumption in the hydrocyclone.
