It is possible to trace the ions and particles trajectories with COMSOL Multiphysics. Fig.8 shows the ion trajectories inside the ion collector at different operating collecting voltage of 10e40 V and air flow rate of about 3 L/min or air flow velocity of about 7.073 m/s. In this simulation, the ionic mass and radius was assumed about 310
18 g and 3010 12 m, respectively[17].It has been observed that the collection efficiency of ions increases with respect to the applied collecting voltage. It was also found that
