This dissertation describes investigations on liquid atomization, the main subject being the development of a novel method of atomization for the production of sprays with small droplet diameters at low flow rates. The working principle of this atomization method is based on the production of monodisperse droplet chains by controlled break-up of liquid jets. These primary droplets disintegrate into small secondary droplets by impinging onto a solid surface, forming a fine spray. Experiments on drop impact atomization revealed that this method of spray production provides the smallest droplet diameters, especially at low flow rates.<\/p>\n
Additionally, a few fundamental studies on multiphase flows are described. The existing theoretical knowledge on the first wind-induced break-up of liquid jets could be extended by considering the axisymmetric gas boundary layer flow around the jets. For non-continuous or pulsating operation of controlled jet break-up, a relationship between the mechanical vibration amplitude and the fluid mechanical initial disturbance amplitude of the jet surface was found.<\/p>","protected":false},"excerpt":{"rendered":"
Die vorliegende Dissertation setzt sich mit der Zerst\u00e4ubung von Fl\u00fcssigkeiten auseinander. Das Hauptaugenmerk liegt auf der Entwicklung eines zeitlich modulierenden Zerst\u00e4ubungsverfahrens f\u00fcr die Erzeugung sehr feiner Sprays bei kleinen Durchs\u00e4tzen der zerst\u00e4ubten Fl\u00fcssigkeit. Das entwickelte Verfahren basiert auf der Erzeugung monodisperser Tropfenketten durch den kontrollierten Zerfall von Fl\u00fcssigkeitsstrahlen.
