Atomization and Sprays

Online Short Course, February 22 - 25, 2021

Course description and aims

The Short Course on Atomization and Sprays is to be held for the sixth time in 2021. 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.


These aspects 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.
