This study introduces a plasma-based aerosol control method using a rotary electrode dielectric barrier discharge reactor (RE-DBDR). Inorganic NaCl aerosol particles were generated and introduced into the reactor, and their collection efficiency was evaluated over a wide particle size range of 10–3000 nm. Experiments were conducted at a fixed electrode rotational speed of 2400 rpm while varying the applied voltage from 0 to 30 kV. Particle number concentrations upstream and downstream of the reactor were measured using a scanning mobility particle sizer (SMPS) and an optical particle counter (OPC). The results demonstrate that increasing the applied voltage significantly enhances aerosol collection efficiency for both submicron and micron-sized particles due to plasma-induced particle charging and electric-field-driven migration. The study clarifies the electrostatic collection behavior of the RE-DBDR and confirms its effectiveness for wide-size-range aerosol control.
