The agglomeration phenomenon of the charged smoke particle has been investigated by the electricfluid mechanics and transport theory of external force field and depending on several simplifying assumptions the theoretical expression for the agglomeration rate of the smoke particles has been developed. In a model of electrostatic precipitator the agglomeration mechanism of charged particles has ...

The ability of a nitride light-emitting diode (LED) to withstand electrostatic discharge (ESD) is important because of the insulating property of the sapphire substrate. Therefore, damage caused by ESD to a nitride LED is a valuable subject. However, damage is caused by ESD in a very short period, so monitoring its evolution is very difficult. Accordingly, ESD experiments are performed and the ...

Let u be the equilibrium potential of a compact set K in R. An electrostatic skeleton of K is a positive measure μ such that the closed support S of μ has connected complement and no interior, and the Newtonian (or logarithmic, when n = 2) potential of μ is equal to u near infinity. We prove the existence of an electrostatic skeleton for every convex polytope. Our proof raises several interesti...

personal samplers or in general blunt body samplers are widely used in occupational hygiene for collecting air contaminants in the work environments. this work is part of an ongoing research into the performance evaluation of personal samplers, particularly in terms of their aerodynamic properties. velocity profiles have been measured around and within typical cylindrical sampling devices, plac...

Fly ash (FA) and Air Pollution Control (APC) residues collected from three municipal solid waste incinerators (MSWI) in Denmark and Greenland were treated by electrodialytic remediation at pilot scale for 8 to 10 h. The original residues and the treated material were analysed for mercury (Hg) in order to assess the influence of the electrodialytic treatment on the concentrations of this element...

The description of molecular systems using multipolar electrostatics calls for automated methods to fit the necessary parameters. In this paper, we describe an open-source software package that allows fitting atomic multipoles (MTPs) from the ab initio electrostatic potential by adequate atom typing and judicious assignment of the local axis system. By enabling the simultaneous fit of several m...
