Abstract.
Based on computational fluid dynamics (CFD) method, applying FLUENT software, taking a de-oil hydrocyclone as an original structure, the effect of porous overflow pipe on the performance and pressure characteristics is analyzed.
Structure Parameters Simulation Effect of Overflow-pipe Diameter Du1.
The simulation of the POP hydrocyclone is compared with that of the traditional hydrocyclone.
By comparing the numerical simulation results of hydrocyclones, oil concentration of the POP hydrocyclone overflow is increased, which is beneficial for the upward movement of oil phase.

Recent years, due to the development of numerical simulation method, the gas flow conditions within the valve was gradually well revealed,which made an inevitable trend in studying the aerodynamic noise characteristics with the combination of the flow field simulation.
The numerical simulation research status of the valve.
With the development of the computer technology and CFD-Computational Fluid Dynamics, numerical simulation plays an increasingly important role in solving flow problems.
In recent years, in the fluids research inside of the valve, numerical simulation was also widely used.
As mentioned above, the acoustic frequency of the turbulent mixing noise and broadband shock noise generated inside of the valve is high, and thus in the simulation of unsteady flow, it must use a very small time step.In addition, the large-eddy simulation is recognized an accurate turbulence model, suitable for noise prediction, however, large-eddy simulation has a high requirement on the grid scale.
