Abstract
The flow field of a new T2shaped stirrer was simulated using the multiple reference frame (MRF) method in the com2 putationalfluiddynamics(CFD)softwareFLUENT.Theintensityofturbulence,flowfieldcharacteristics,meanvelocitydistri2 bution, and mixing pow er of the T2shaped stirrer, open turbine stirrer, and rushton turbine stirrer w ere analyzed and com pared, and the results suggested that the T2shaped stirrer has a better flow field distribution to achieve better mixing effects. T he mix2 ing characteristicsofT2shapedstirrerwithdifferentmountingheightswereanalyzed,andthebestmountingheightwasobtained as 150mm under the condition of fixed stirred tank size. The turbulence intensity and mixing pow er of the T2shaped stirrer with different numbers of blades were investigated, which showed that the mixing power increases with the increasing number of bladesandtheT2shapedstirrerwith3bladeshasthebestturbulenceintensitydistribution.Theresearchcanprovideanimpor2 tant basis for the analysis and development of new stirrer.关键词
