Atomization of liquids by a novel technique

Abstract

The usefulness of sprays in a wide range of industrial applications (combustion, coating, spray drying, etc.) makes the understanding of the atomization process very valuable, specially to choose the most suitable atomizer for each application. Due to the great importance of the size of the resulting drops, new techniques that enable the control of the spray formation are emerging. One of these techniques is the vibrational excitation of at-fan liquid sheets developed by Brenn et al., which is the focus of the present work. Liquids with di erent properties are used to analyse the performance of the spray under several operating conditions. The main goal is to obtain the size of the droplets and their spectrum in each case.
