SALINAS-SALAS, Gonzalo  and  ESPINOSA-FUENTES, Fernando. EXPERIMENTAL EVALUATION OF THE BEHAVIOUR OF THE SEDIMENTATION VELOCITY OF PARTICLES. Rev. ing. univ. Medellín [online]. 2012, vol.11, n.20, pp.239-250. ISSN 1692-3324.

This article presents the theoretical aspects, methodology, results and conclusions of a study developed to determine the behavior of the terminal settling velocity of noncolloidal particles systems of average sizes smaller than 1,000 nm in comparison to larger particles system. In order to do this, an analysis of the behavior of the reduction factor of terminal velocity of sedimentation was made. Due to the extreme complexity of the phenomenology of the sedimentation process of average particles systems in diameters smaller than 1,000 nm, an experimental work was required. The results indicate that there is a difference between the behavior of the velocity settling of particle systems greater than 1,000 nm, for systems of particles which size is smaller than this, what impacts the value that takes the correction factor.

Keywords : Velocity of sedimentation; systems of particles; correction factor; experimental work.
