Drops, Sprays and Atomization

Last Day for Registration : January 13, 2024


SKU: IIT Madras | Date: 17th - 20th January, 2024 Categories: ,

Course Description & Aim

This short course has the aim to present the current understanding and state of the art of atomization fundamentals, their realisation 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 drop-lets – secondary atomization. These fundamentals are followed by topics on diagnostics, numerical simulations, drop/wall interactions and further 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.
