| Abstract: | A packing model of rotating ellipsoids was presented to simulate the pack-ing state of magnetic acicular particles in this paper.The packing fractionand the packing density of particles have been calculated.In those calcula-tions,the effects of packing form,axis ratio,azimuth factor,orientating factorand size uniformity on the packing fraction have been also evaluated.The cal-culating results are consistent with the experimental values quite well. |
