Course Description & Aim

This short course aims to present the current understanding and state of the art of capillarity (wetting, capillary flow, surface fabrication), drops (sessile, impacting,  sliding) atomization fundamentals, and generation and application of sprays in a variety of engineering branches, including spray drying, spray coating, spray cooling, fuel injection, etc.

These aspects are addressed theoretically in terms of hydrodynamic instabilities of liquid jets and sheets, followed by mechanisms of breakup and coalescence of single drops.

These fundamentals are accompanied by topics on diagnostics and numerical simulations as well as advanced topics and applications. 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.
