Effect of coagulation on the asymmetric charging of aerosols

Charge distributions of aerosol dioctyl sebacate particles charged in a dielectric barrier discharger

“…This was attributed to the increase in charging probability with increasing particle size. Moreover, the results show that the ratio between positive and negative charges decreased with increasing particle size, as discussed in the previous studies (Dhanorkar & Kamra, 2003;Hinds, 1999;Hoppel & Frick, 1986). Table 1 shows the average particle charge (positive or negative) at different particle sizes.…”
