Reliability Analysis for Application of CFD to Hydrocyclone Internal Flow Field

CFD technology was introduced briefly,with which numerical research was carried on. Computational models for Hydrocyclone were discussed,including the choice of turbulence model,multiphase flow model and calculation method for air column. Numerical simulation for taper hydrocyclone was taken as an example.Static pressure cloud chart,velocity cloud chart and vectorgraph of hydroclone internal flow field were achieved. Comparison between the simulation results and practice was made to prove the reliability with the directive significance to hydrocyclone optimization design and performance analysis.
