描述This thesis proposes new approaches for modelling contacting 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. Scaling laws of cloud radius and particle number density are obtained by solving a continuum convection equation. Finally, it investigates the deposition of charged particles on a flat plane and fibers. A dimensionless adhesion parameter is constructed to predict the structure of deposits. The temporal evolution of the deposit structure, particle capture efficiency, and the pressure drop are displayed with varying values of Coulomb repulsion and adhesion magnitudes.?

,A Fast Discrete Element Method for?Adhesive Particles,ays are analyzed and the effect of particle size, and impact angles on the critical sticking velocity is discussed. An explicit formula is put forward as a sticking/rebound criterion for collisions of micron-sized particles covering different impact angles, particle sizes, and size ratios. We then p

,Migration of?Cloud of?Low-Reynolds-Number Particles with?Coulombic and?Hydrodynamic Interactions,namic interactions are modelled by Oseen equations and the Coulomb repulsion is calculated through pairwise summation. It is shown that a strong Coulomb repulsion can prevent the breakup of the clouds covering a wide range of particle Reynolds number and cloud-to-particle size ratio. A dimensionless

,Deposition of?Microparticles with?Coulomb Repulsion,rocess and the final obtained structures of ballistic packings are studied to show the effect of interparticle Coulomb force. It is found that increasing the charge on particles causes a remarkable decrease of the packing volume fraction and the average coordination number, indicating a looser and c
