W. Egli et al., 3D COMPUTATION OF CORONA, ION-INDUCED SECONDARY FLOWS AND PARTICLE MOTION IN TECHNICAL ESP CONFIGURATIONS, Journal of electrostatics, 40-1, 1997, pp. 425-430
Recent achievements in the development of a theoretical model for elec
trostatic precipitation are described. The challenges are the treatmen
t of complex three-dimensional geometries, and the complexity of the p
hysical effects together with the multi-disciplinarity of the overall
problem. Different computational modules are used for the computation
of the electric field, the corona discharge, the ion drift regions and
their interaction with the main gas flow. Results are given for curre
nt density distributions, secondary flow patterns and the particle dis
tribution. The computational modules are integrated in a domain-decomp
osition based environment that allows for concurrent engineering and p
rogram development.
