About: Flow focusing

An Entity of Type: company, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org:8891

Flow focusing in fluid dynamics is a technology whose aim is the production of drops or bubbles by straightforward hydrodynamic means. The output is a dispersed liquid or gas, frequently in the form of a fine aerosol or an emulsion. No other driving force is required, apart from traditional pumping, a key difference with other comparable technologies, such as electrospray (where an electric field is needed). Both flow focusing and electrospray working in their most extensively used regime produce high quality sprays composed by homogeneous and well-controlled-size droplets. Flow focusing was invented by Prof. Alfonso M. Gañan-Calvo (who now teaches at ETSI in Seville) in 1994, patented in 1996, and published for the first time in 1998.
