Aerosol charging has been subject of research for a long time. The theoretical charge limits, the charging mechanisms and experiments of charging of aerosol particles have been reported in literature, in several research fields. In the applications different kinds of chargers are used, resulting in different amount of charges on the same aerosol particle.
We are interested to find the highest charge level that can be achieved
with a (corona) charger. In this paper a robust method to compare electrical aerosol chargers is presented. This model makes the charging theories more transparent and is not dependent on assumed values of for example
w the MathML source"">Nit. The particle charging equations, kno
wn from aerosol technology, are combined
with basic physical models kno
wn from electrical engineering. The model is experimentally tested
with a corona needle charger and
with results from literature.
