A domain decomposition method for three species modeling of multielectrode negative corona discharge with applications to electrostatic precipitators
Journal article, 2015
The negative corona discharge problem for multi-electrode geometries is modeled by a three species
model. The equations are solved using domain decomposition, by recognizing that multiple species are
only present in a small part of the domain, and hence only need to be incorporated locally in the model.
The method is applied to an industrially relevant three wire electrostatic precipitator geometry. The
calculated current density is in good agreement with experimental data. To further illustrate applications
of the three species solution, it is used for coupled particle, fluid, and electrostatic simulations to analyze
particle collection properties.
