“…A microplasma actuator similar to the one shown in Figure 2 was developed. The schematic of a DBD microplasma actuator is shown in Figure 10 [ 32,41]. It consists of 20 strip-like electrodes with a 200 μm width and 16 μm thickness (top-side electrode) which are placed above a plate-like electrode (bottom-side electrode) with a dielectric layer of 25 μm thicknesses in between.…”

Dielectric barrier discharge (DBD) plasma actuators are a technology which could replace conventional actuators due to their simple construction, lack of moving parts, and fast response. This type of actuator modifies the airflow due to electrohydrodynamic (EHD) force. The EHD phenomenon occurs due to the momentum transfer from charged species accelerated by an electric field to neutral molecules by collision. This chapter presents a study carried out to investigate experimentally and by numerical simulations a microscale plasma actuator. A microplasma requires a low discharge voltage to generate about 1 kV at atmospheric pressure. A multi-electrode microplasma actuator was used which allowed the electrodes to be energized at different potentials or waveforms, thus changing the direction of the flow. The modification of the flow at various time intervals was tracked by a high-speed camera. The numerical simulation was carried out using the Suzen-Huang model and the Navier-Stokes equations.

“…There are many electrostatic applications for the control of particle position (Matsusaka et al, 2008), separation (Dwari et al, 2015), classification (Kawamoto, 2008), and surface cleaning (Mazumder et al, 2007;Kawamoto et al, 2011). In addition, there are reports regarding particle levitation using various configurations of electrodes (Adachi et al, 2016;Blajan et al, 2017). These electric fields allow particles to move even in the absence of mechanical and/or pneumatic systems.…”

Electrostatic forces cause spontaneous movement of charged particles; subsequently, electrostatic technology is attracting attention because of its application in powder handling processes, such as separation, classification, dispersion, and collection. Dielectric and conductive particles are charged by induction in a strong electric field and moved by Coulomb forces. The magnitude and polarity of the transferred charges are controlled by the strength and direction of the electric field. The dielectric particles are also polarized in the electric field, and dipole interactions occur between particles or in the particle layers, complicating the particle behavior. This review paper presents induction charging, agglomeration, levitation, and other behaviors resulting from particle layers in electric fields. A series of particle phenomena occur in parallel electrode systems, which consist of a lower plate electrode and an upper mesh electrode. Charged agglomerates are formed on the particle layers, levitated by the Coulomb forces, and disintegrated with rotation when approaching the mesh electrode. The mechanisms of agglomeration and disintegration have been elucidated in multiple studies, including microscopic observations and theoretical analyses of particle motion, based on numerical calculations of the electric field. Furthermore, a new system is proposed for continuous feeding of dispersed particles using electric fields and vibration.

“…Microplasma actuator has small dimensions; thus the EHD flow measurements are difficult to carry out. Besides the experimental investigation, numerical simulation software was developed to study the microplasma actuator phenomena especially near the electrode surface where, due to the light emission, the measurements were difficult [25][26][27][28].…”

Dielectric barrier discharge microplasma is a nonthermal plasma discharge at atmospheric pressure which due to the micrometer size dielectric layer between the grounded and high-voltage energized electrodes enables to drive the device at less than 1 kV. Microplasma is an economical and ecological alternative for conventional technologies used for NOx removal, indoor air cleaning, surface treatment of polymers, biomedical applications such as transdermal drug delivery, or as an actuator. In this chapter, microplasma applications such as indoor air purification, skin treatment for drug delivery, particle removal, and flow control are presented.
