Shape Description and Sedimentation Characteristics of Non Spherical Regular Particles

摘要：

　　The research progress on settling characteristics of non-spherical particles is summarized.Three new filling coefficients in three directions of cuboid are defined.Combining with the existing parameters, a new mathematical model of drag coefficient CD is proposed that using six variables describes the shape information of arbitrary shape particles.This equation is derived and shows reasonable accuracy with the error being less than 1%.
