One-dimensional structure of multi-component fine particle (dust) clouds under gravity

Publication date: Available online 10 April 2019Source: Physics Letters AAuthor(s): Hiroo TotsujiAbstractThe structure of electrostatic potential and the distribution of fine particle (dust) clouds are analyzed in the case where we have fine particles of multiple components in plasmas under gravity. This extends the model for one-dimensional structures of fine particle cloud based on the enhanced charge neutrality in clouds to multi-species cases. Fine particles of different species are shown to form stratified clouds with simply expressed mutual separations. The results may be applied to analyze or segregate mixtures of dusts in atmospheres.
