“…Removal of PMs is one of the major objectives for air filtering technology. Nowadays, fibrous filtering and electrostatic precipitation are the two most common technologies for removing the airborne PMs [13][14][15][16][17][18][19][20][21]. The fibrous filter, which uses multilayered randomly or regularly organized fibers to separate the PMs from the air stream with the minimum energy consumption, as shown in figure 1(a), has been widely applied for simple structure and low material costs [13,14].…”

“…The removal efficiency and pressure drop have the contrary relationship, determining the performance of the fibrous filter together. The electrostatic precipitator adopting the electrostatic precipitation technology has been widely applied in industry filter [18,19]. Compared with the fibrous filter, the electrostatic precipitator has the obvious advantages of high removal efficiency and low pressure drop [20].…”

Air pollution becomes more and more serious with the rapid development of the society, and the haze caused by particulate matters (PMs) has become a global problem. Thus seeking an effective technology for removing the airborne PMs or other pollutants is much desirable for alleviating the air pollution. The newly invented triboelectric nanotechnology can realize efficient air filtering with obvious advantages over traditional fibrous filtering and electrostatic precipitation. Here, a review is provided for recent progress in air filter by utilizing the triboelectric nanotechnology, starting from the choices of triboelectric materials and main features of triboelectric nanotechnology. The mechanism of triboelectric air filtering technology was presented as the coupling of triboelectric filtering and mechanical filtering. Then the approaches of air filtering were summarized as the triboelectric nanogenerator (TENG)-driven air filtering, TENG-enhanced nanofiber air filtering, and self-powered triboelectric air filtering. The device structure, working principle and filtering performance were systematically discussed. Furthermore, the industry products which have been developed based on the triboelectric filtering technology were introduced.

A dielectric barrier discharge actuator to control airflow along a flat dielectric plate has been numerically investigated in this paper. In order to avoid large computing times, streamers, Trichel pulses and the ionic reactions involving photons and electrons are neglected. The numerical model assumes two types of generic ions, one positive and one negative, whose drift in the electric field produces the electrohydrodynamic flow. This study provides detailed insights into the physical mechanisms of DBD that include the electric field, space charge transport, surface charge accumulation and air flow motion. The results show the V-I characteristics, velocity profiles and drag force estimates. In addition, the effects of the voltage level, frequency and inlet air velocity on the actuator performance are presented and interpreted. The simulation results show a good agreement with theoretical expectations and experimental data available in literature.
