GRAVITY SEDIMENTATION OF A SET OF SOLID SPHERICAL PARTICLES IN THE REGIME OF A PARTIALLY BLOWN CLOUD

Results of experimental study of the process of gravity sedimentation of a set of solid spherical particles in the regime of a partially blown cloud in a wide range for Reynolds numbers have been presented. A new method to create a spherical cloud of particles has been proposed. Based on the experimental data on the change in the settling velocity of the particles as a function of time and of the covered distance, a criterial dependence has been obtained for the coeffi cient of resistance of the set of particles in the sedimentation regime under study.
