Analysis of corona discharge in wire-cylinder ESP with and without particle loading

2016 | الكلمات المفتاحية Electrostatic precipitator, corona discharge, particle loading, electric field, Poisson's equations,
Analysis of corona discharge in wire-cylinder ESP with and without particle loading
This paper is aimed at investigating thoroughly the corona performance in the wirecylinder ESP with and without loading by suspended particles in the exhaust of a diesel engine. The onset voltage of negative corona on the discharge wire is calculated based on the criterion of self-sustained discharge. The ionized space between the discharge wire and the collecting cylinder of the ... إقراء المزيد

Corona performance in wire-cylinder ESP with particle loading
This paper is aimed at investigating thoroughly the corona performance in the wire-cylinder electrostatic precipitor (ESP) with loading by suspended particles in the exhaust of a diesel engine. The onset voltage of negative corona on the discharge wire is calculated based on the criterion of self-sustained discharge. The ionized field in the ESP is mathematically modeled for calculating the spatial ... إقراء المزيد

Corona performance in wire-cylinder ESP without particle loading
This paper is aimed at investigating thoroughly the corona performance in the wirecylinder electrostatic precipitor (ESP) without suspended particles. The onset voltage of negative corona on the discharge wire is calculated based on the criterion of self-sustained discharge. The ionized field in the ESP is mathematically modeled for calculating the spatial distribution of the space-charge density due to the corona ... إقراء المزيد

Particles' Re-entrainment in Electrostatic Precipitators

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

Performance of Positive Corona in Tree-Shaped Multi-Needle-to-Plane Configurations

2015 | الكلمات المفتاحية Charge simulation, positive corona, streamer theory, , tree-shaped electrodes, corona onset voltage,
Performance of Positive Corona in Tree-Shaped Multi-Needle-to-Plane Configurations
This paper is aimed at investigating the electric field, the positive-corona onset-voltage and current-voltage relationship of tree-shaped multi-needle-to-plane configurations. The configurations include 1, 5, 9, 13 and 17 needles arranged in one, two and three layers. The well-known charge simulation method was used to calculate the electric field in the gap spacing between positively-stressed needle-arrangements and opposite ground plane. Based ... إقراء المزيد
