Engineering The Preparation of Electrohydrodynamic Bridges from Polar Dielectric Liquids Adam D. Wexler1, Mónica López Sáenz2, Oliver Schreer2, Jakob Woisetschläger3, Elmar C. Fuchs1 1Applied Water Physics, Wetsus - Centre of Excellence for Sustainable Water Technology, 2IRCAM GmbH, 3Institute for Thermal Turbomachinery and Machine Dynamics, Graz University of Technology Horizontal and vertical electrohydrodynamic liquid bridges are simple and powerful tools for exploring the interaction of high intensity electric fields and polar dielectric liquids. The construction of basic apparatus and operational examples, including thermographic images, for three liquids (e.g., water, DMSO, and glycerol) is presented.
