Particles' Re-entrainment in Electrostatic Precipitators
This paper is aimed at investigating the reentrainment phenomena of particles in wire-duct electrostatic precipitators. This calls for assessment of the forces acting on a particle positioned in the precipitator nearby the collecting plate. These include Van Der Waals, Johnsen Rahbek and repulsion forces. Re-entrainment takes place when the repulsion force exceeds the resultant of both the Van Der Waal ... إقراء المزيد

On the Development of Upward Streamers from a Tree-shaped Multi-needle Arrangement during Progress of a Downward Leader
This paper is aimed at investigating the development of an upward streamer from a grounded tree-shaped multi-needle arrangement during the progress of a downward leader. The downward leader is simulated by a point charge at tip and a finite line charge extending along the leader length. The field enhancement in the vicinity of the needle arrangement in presence of the ... إقراء المزيد
