Electrohydrodynamic and Charged Particle Transport and Deposition
A corona is an instrument that is used in copy machines and printers. Since the
contamination by particles causes that the quality of prints or copies decrease
dramatically, finding the methods that decrease the amount of contaminants looks
necessary. In this regard, by analyzing the movement of particles inside and outside
of a corona, some methods can be offered to decrease the amount of the contaminants.
In corona, charged particles move in a charged flow in the presence of an external
electrical field, so this problem is categorized as a EHD problem. The governing equations
for the flow and electrical fields are strongly coupled that have to be solved numerically
and then the result of that step is used in the Lagrangian equation of motion for particles
that gives the desired information.
