Short Course on Atomization & Sprays 2017
February 20-23, 2017 Darmstadt, Germany
We 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. The course is offered by the profile area Thermo-Fluids & Interfaces in cooperation with DFG SFB/TRR 75.
From theory to practice
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.
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 renowned expert and get in touch with people from the industry
The program foresees intensive discussions between the participants and the lecturers and also among the participants. The aim is to address on-going development and application problems suggested by the participants. Industrial exhibitors of spray diagnostics will be available on the second day for demonstrations and discussions.
The course language is English.
