A finite volume method for electrostatic three species negative corona discharge simulations with application to externally charged powder bells

A domain decomposition method for three species modeling of multi-electrode negative corona discharge – With applications to electrostatic precipitators

“…Readers are referred to [1,10,22,23,27] for a more detailed description. Simulations will primarily be performed in air, except for Section 4 where oxygen is used.…”

“…Denoting electrons by e and following [10,27], we let the positive and negative ions in the model be represented by the positive and negative oxygen ions O þ 2 and O À 2 . These are associated with linear ionization and attachment reactions:…”

“…We have previously presented an approach using a finite volume discretization for both the charge densities and the potential in Ref. [10].…”

“…The three species part of the simulation domain is solved using the method presented in Ref. [10], which uses an unstructured two dimensional mesh. We will therefore restrict this study to electrodes with a symmetry direction, i.e.…”

Simulation of physical processes in devices with non-magnetic, milk-dispersed secondary part

“…It should be noted that in the study of physical processes in the "comb-grid" type of organization, modeling is performed proceeding from the assumption of a plane-parallel picture of the field in the interelectrode space [10][11][12][13]. Such an assumption becomes possible in the case when the distance between the electrodes belonging to the same comb is small enough to introduce significant distortions in the picture of the processes occurring.…”
