Electrohydrodynamic (EHD) technology generates airflow without moving parts, making it a reliable solution for various low-energy applications. EHD-based devices enhance patterns, resulting in significant energy savings air-moving systems. This airflow, also known as ionic wind, is created through Corona discharge, which accelerates electrically charged air molecules strong electric field. Curr...

Functional nano-microfibers and capsules developed using electrohydrodynamic (EHD) processing methods for the encapsulation of probiotics are reviewed. The properties polysaccharides, proteins, or hybrids compounds utilized encapsulation, characteristics tailor-made matrices by EHD, facilitate high long-term viability cells. ability electrospun fibers electrosprayed to incorporate other functio...

Fluidic interfaces disintegrate under sufficiently strong electric fields, leading to electrohydrodynamic (EHD) tip streaming. Taylor cones, which emit charged droplets from the of a conical cusp, are among most prominent and well-studied examples EHD instabilities. In liquid-liquid systems, more complex interface deformation modes than simple cones can be observed, with being pushed away elect...

Abstract The usage of journal bearings as planetary in wind turbines instead roller has become more common recent years. Their is advantageous, due to smaller installation space needed compared allowing for higher power densities turbine drive trains. However, this technology presents a challenge since there currently no standardized approach the design regarding wear. Due varying speeds and dy...

In our previous studies we have shown that particles adsorbed on the surface of a drop can be concentrated at its poles or equator by applying a uniform electric field. This happens because even when the applied electric field is uniform the electric field on the surface of the drop is nonuniform, and so particles adsorbed on the surface are subjected to dielectrophoretic (DEP) forces. In this ...

Previous work has characterized electrohydrodynamic (EHD) thruster performance, determining that thrust-to-power ratios are comparable with that of conventional propulsion at the laboratory scale. Achievable thrust density of EHD propulsion has yet to be experimentally quantified and could be a limiting factor in its application. In this paper, we quantify the achievable thrust density for a wi...

The conventional methods of drying Chinese wolfberry fruits cause loss of active ingredients and the drying time is very long. In order to explore and investigate the new method of drying Chinese wolfberry fruits, electrohydrodynamic (EHD) drying system was used to drying for Chinese wolfberry fruits with a multiple needle-to-plate electrode on five levels alternating voltage at 0, 20, 24, 28 a...
