【 摘 要 】

This paper presents the results of the numerical studies of the non-spherical particles separation in the hydrocyclones. The calculations are done for freely rotating particles, and particles with orientations fixed by means of an external torque exerted by a strong orienting field. The results demonstrate that separation characteristics of the hydrocyclone are strongly depends on the flow shear rate, particle size, and particle shape. The model is validated by the good agreement between the measured and predicted results.
