Abstract

This paper presents an wall loss reduction technique using electrodynamic disturbances. First, the proposed technique is applied to a general microchannel as a feasibility test, and then it is applied to a virtual impactor, which is an inertial airborne particle classifier used for environmental monitoring. In the microchannel application, when the electric potential was 3 kV at 1 kHz, wall loss was decreased by 16% for particles with a 0.89 μm diameter. In the virtual impactor, wall loss curve of 1 kV at 1 kHz showed a maximum wall loss reduction of 10% compared with initial wall loss curve.
