“…A constant 10 cm s À1 air ow is chosen because it is a typical condition chosen in the literatures. 23,48,49 For both modes, the spatial and temporal dispersions of PM are monitored using a home-made laser light scattering setup, as described below.…”

“…In addition to the effect of the induced ow, other factors could potentially inuence the PM removal behavior such as particle densities, 28 particle size distribution, 35 composition of particle, 34 distance between discharge and ground electrode, 26 and the electrode geometry. 23 The existence of a conned area within which PM is removed effectively provides a new route for developing personal and wearable cleaning devices to purify air. With the geometry connement, ESP devices can more efficiently remove PM in the localized region dened by the electrode and the geometric design.…”

“…18,19 ESP devices consist of an electrode with a small radius of curvature and collecting plates. 20 These devices are typically designed in the wire-plate (parallel-plate ESP), 21 needle-plate, 22 or wire-duct (tubular ESP) 23 geometries. To generate corona discharges around the sharp edge, a high voltage with either positive or negative polarity is applied to the electrode.…”

“…In this regard, some research has focused on how poor indoor air quality amplifies the effects of airborne viruses, including the COVID-19 coronavirus [17]. One of the most important strategies to address this 2 of 20 issue is using indoor air filtration and purification devices, besides the air ventilation systems [18][19][20].…”

In addition to public health measures, including social distancing, masking, cleaning, surface disinfection, etc., ventilation and air filtration can be a key component of a multi-pronged risk mitigation strategy against COVID-19 transmission indoors. Electrostatic precipitators (ESP) have already proved their high performance in fluid filtration, particularly in industrial applications, to control exhaust gas emissions and remove fine and superfine particles from the flowing gas, using high-voltage electrostatic fields and forces. In this contribution, a high-voltage electrostatic sanitizer (ESS), based on the electrostatic precipitation concept, is proposed as a supportive measure to reduce indoor air infection and prevent the spread of COVID-19 coronavirus. The finite element method (FEM) is used to model and simulate the proposed ESS, taking into account three main mechanisms involving in electrostatic sanitization, namely electrostatic field, airflow, and aerosol charging and tracing, which are mutually coupled to each other and occur simultaneously during the sanitization process. To consider the capability of the designed ESS in capturing superfine particles, functional parameters of the developed ESS, such as air velocity, electric potential, and space charge density, inside the ESS are investigated using the developed FEM model. Simulation results demonstrate the ability of the designed ESS in capturing aerosols containing coronavirus, precipitating suspended viral particles, and trapping them in oppositely charged electrode plates.
