معرفی
Nathanaël Machicoane is a CNRS Researcher at the Laboratory of Geophysical and Industrial Flows (LEGI) within Grenoble Institute of Technology at University Grenoble Alps. His research focuses on experimental and theoretical aspects of fluid dynamics, particularly in multiphase flows, atomization processes, and turbulence phenomena. He leads investigations using advanced imaging techniques including X-ray radiography and high-speed visualization to study complex fluid behaviors.
His educational background includes a Habilitation from University Grenoble Alps (2024), a Ph.D. in Fluid Mechanics from ENS de Lyon (2014), and a Master degree in Physics from ENS de Lyon (2011). Prior to his current position, he completed postdoctoral research at the University of Washington's Multiphase & Cardiovascular Flow Lab (2016-2020) and at FAST laboratory.
Machicoane's research interests span atomization and sprays, multiphase flows, turbulence, drops and bubbles, geophysical flows, particles/flow interactions and transport, heat transfer, mixing in two-phase flows, and Lagrangian and Eulerian approaches. His work combines theoretical modeling with sophisticated experimental techniques to investigate fundamental fluid phenomena with applications ranging from industrial processes to biomedical engineering. He has developed expertise in using synchrotron-based X-ray imaging to study liquid jet fragmentation and spray formation mechanisms.
His publication record shows a strong focus on atomization mechanisms, particularly gas-assisted atomization, with significant contributions to understanding liquid jet fragmentation, spray formation, and particle dynamics in turbulent flows. His recent work increasingly incorporates advanced imaging techniques and computational validation, with emerging applications in biomedical fluid dynamics as evidenced by his publications on intracranial aneurysm hemodynamics.
Machicoane actively participates in the EDT (Two-Phase Flows and Turbulence) team at LEGI, utilizing the laboratory's extensive experimental facilities including hydrodynamic tunnels, rotating platforms, and wave channels. His research often involves international collaborations with institutions such as the University of Washington, where he previously conducted postdoctoral research.
His laboratory work employs a variety of sophisticated experimental setups, including high-speed flow visualization systems, Phase Doppler Particle Analysis, and synchrotron-based X-ray imaging. These techniques enable detailed characterization of complex fluid phenomena at multiple scales, from macroscopic spray patterns to microscopic interfacial dynamics.
