Abstract: The sedimentation of slender particles with different densities in stagnant Newtonian fluid was studied. Different from former studies based on the concept of sphericity, the drag coefficient of slender particles is quantitatively correlated with the orientation and Reynolds number based on the particle cylindrical diameter. With the aid of Galileo number,the particle cylindrical diameter, the proposed correlation represents very well the experimental data with aspect ratios, orientations, particle material and fluid properties in wide ranges.
