Atomization and Sprays

Online Short Course, 22–25 February and 17–20 May 2021

Course description and aims

This year, the Short Course on Atomization and Sprays will be held online in February and May. As in the previous six editions, the aim is to present the current understanding and state-of-the-art of atomization fundamentals, their realization in atomizer systems and their application in a wide variety of engineering branches, including spray drying, spray coating, spray cooling, fuel injection, etc.

Course description


The current understanding of atomization fundamentals are first addressed theoretically in terms of hydrodynamic instabilities of liquid jets and sheets – primary atomization. This is followed by considerations about the break-up of single droplets – secondary atomization. Engineering solutions for realizing the different atomization mechanisms are then presented.

Characterization and diagnostics

The second day is devoted to experimental descriptors and diagnostics of sprays and droplets. Both non-optical and optical techniques are addressed. Focus is placed on drop size and velocity determination, but an overview is also given about more advanced techniques, allowing temperature and composition to be determined.

Modeling and simulation

The third day presents possibilities for simulating atomization and spray processes. Modelling of primary atomization is discussed, as well as transport processes within sprays and spray/wall interactions.

The final day of the course covers a wide variety of applications and how spray systems have been developed and customized to meet specific requirements and constraints.

Discuss with experts and the community

The program foresees discussions among the participants and the lecturers. The aim is to address on-going development and application problems suggested by the participants.

Who should attend?

This course is directed towards practicing engineers, researchers involved in R&D and the application of spray systems, and graduate students performing research on the subject of sprays and atomization. For those with little previous background, the course begins with fundamentals of atomization and proceeds through theoretical, experimental, numerical and application topics.

Format, fees and registration

Lectures will be aired using Webex, either live or recorded. In either case, the lecturer will be available during the lecture period and questions and discussions with lecturers will be moderated through the chat function.

Course fees

  • Industry: 200 EUR
  • Academia: 100 EUR

Course fees are VAT exempt according to article 132 (i) Council Directive 2006/112/EC.

The lectures will be available for streaming as of their time of airing and for the subsequent 24 hours, allowing those in different time zones or those unable to attend a particular lecture, to view the lecture at their convenience. The chat discussion during the lecture and discussion after the lecture with the lecturer will not be recorded and will only be available during the presentation.


We prefer payment via wire transfer (bank transfer). Payment via credit card (VISA and Master Card only) is possible upon request. Please contact Cameron Tropea () for the terms and conditions.
