| Abstract: | The separating property of a horizontal settling centrifuge is studied,and FLUENT software is used to build 3D model of two-phase turbulance in the centrifuge.It is mainly analyzed the effect of different ratio of length to diameter of the centrifuge drum on the separating property of the centrifuge,and indirectly given a relationship range of different ratio of length to diameter,the best geometrical size of centrifuge drum is got,which offers a reference to the further study of the influence on the effective separation by the centrifuge parameter and its structural optimization. |
