Microparticle Dynamics In Electrostatic And Flow Fields

This Thesis Proposes Approaches For Modelling Ing Interactions And Electrostatic Interactions Between Microparticles In The Framework Of The Discrete Element Method And Presents A Systematic Investigation On The Agglomeration, Migration And Deposition Of Microparticles In Presence Of Electrostatic And Flow Fields. It Reports An Exponential-form Scaling For The Size Distribution Of Early-stage Agglomerates In Homogeneous Isotropic Turbulence And Formulate The Agglomeration And Deagglomeration Rates. The Evolution Of Spherical Clouds Of Charged Particles That Migrate Under The Action Of An External Electrostatic Field Is Then Investigated.
