The Laboratoire des Ecoulements Géophysiques et Industriels (LEGI) is looking for a PhD student to work on atomisation.
Assisted atomization is widely used in industry (manufacturing, pharmaceutical, agricultural…) to produce a high-quality sprays. A high-speed gas surrounds a low-momentum liquid jet, accelerating it and making it unstable, to successively break it into a cloud of fine droplets, namely a spray. In the context of propulsion application, the gas entering the nozzle goes through the jet engine turbines and becomes highly turbulent, with large velocity fluctuations as well as angular momentum, referred to as swirl.
The aim of this PhD project is to improve our understanding of this turbulent multiphase flow, suing a multiscale experimental approach, studying the spray from the near-field of the atomizer, where interfacial instabilities form on the liquid jet, to the far-field, where droplets are dispersed by the turbulent phase.
The LEGI is looking for a PhD candidate with strong background in fluid mechanics and a high interest in experimental research.
