04 O 01 The electrohydrodynamics of electrified conical menisci

摘要: Abstract Electrostatic atomization of liquids has become a hot research area since the new and promising characteristics resulting spray have been brought to light, namely its fairly monodisperse size distribution, small controllable droplet size. In present work, using perturbation techniques matched asymptotic analysis (Van Dyke, 1964; Kevorkian Cole, 1980) based on parameter 1 , Taylor's electrostatic theory for electrified liquid cones (Taylor, 1964) extended in order take into account charge emissions form capillary microjet. Our results show analytically first time size, charge, emmited current as functions properties (essentially electric conductivity, surface tension, density) injected flow rate . This allows serious approaching real design an entirely fuel injection device generation.
