Comparison of several turbulent models for calculating turbulent separated flows passing on sill

Phosphoric acid production wastewater was treated by flocculation-cyclone separation process and recirculated to phosphoric acid production process,recovering phosphorussubstances from the wastewater and saving a great quantity of industrial water.

The paper introduces a cyclone separation cleaning technology,and some problems should be solved in applying it.

Now that the current 3-phase separators have many defects,by means of the study of gas-liquid’s kinematic relation in cyclone separation and the study of oil/water separation in gravity sett.

Characterization of wheat flour particles utilizing gravitational field-flow fractionation and digital image processing;

Application of the technology of gravitational field coupled with thermal field-flow fractionation to Niuhuangqingfeisan

This paper discusses the feasibility of Chinese traditional medicine separation using gravitational field-flow fractionation.

The experimental investigation was performed for votex generator jets(VGJs)controlling flow separation occurred in the suction side of low pressure turbine at low Reynolds number conditions.

The flow filed of compressor cascades with three large camber angles at different incidences is measured by five-hole probe in details,and the influence of flow separation and vortex structure on the compressor bowed cascade aerodynamic performances was numerically studied.

90×10~4,the flow separation around the circular cylinder can be suppressed effectively,the separated flow field can also be improved greatly owing to the flow disturbance.
