Sprays are among the most intellectually challenging and practically important topics in fluid
mechanics. This paper reviews needs, milestones, challenges, and a broad array of …

The production of a liquid spray can be summarized as the succession of the following three
steps; the liquid flow ejection, the primary breakup mechanism and the secondary breakup …

Understanding the transmission phenomena of SARS-CoV-2 by virus-laden droplets and
aerosols is of paramount importance for controlling the current COVID-19 pandemic …

Primary atomization of liquid injected at high speed into still air is investigated to elucidate
physical processes by direct numerical simulation. With sufficient grid resolution, ligament …

This work deals with numerical simulations of atomization with high Weber and Reynolds
values. A special attention has been devoted to the modelling of primary break-up. Due to …

Abstract Liquid Metal Jet Printing (LMJP) is a revolutionary three-dimensional (3D) printing
technique in fast but low-cost additive manufacturing. The driving force is produced by …

Droplet size distribution during ultrasonic atomization was investigated by laser diffraction
based on two phenomena—capillary waves and cavitation. The former was visually …

In this study, the measurement of droplet size distribution by means of a laser diffraction
technique in ultrasonic spray pyrolysis was investigated. Effects of precursor temperature …

To promote the design and optimization as well as a deeper understanding of pintle
injectors further, the progress on atomization and mixing characteristics of pintle injectors …

In order to allow for more reliable modelling of microscale processes in turbulent bubbly
flows, detailed experiments in a laboratory-scale double loop facility and a bubble column …
