Stéphane Viazzo

Stéphane Viazzo is a Lecturer with Habilitation to Supervise Research (HDR) at Aix-Marseille Université (AMU), affiliated with the M2P2 Institute (Institute of Mechanics, Civil Engineering and Environmental Sciences). He is a member of the Thermodynamics, Waves, Digital, Interfaces and Combustion research team within the Faculty of Science.

His research focuses on fluid dynamics, particularly in rotating systems. Key areas include:

• Rotating flows: Taylor-Couette systems, Taylor-Couette Poiseuille flows, baroclinic and stratorotational instabilities
• Direct and large-eddy turbulent simulations, including jet impacting rotating disks
• Numerical simulations around deformable bodies, with applications to fish swimming
• Development and application of high-order numerical methods for fluid flow problems

Dr. Viazzo's work demonstrates a strong emphasis on computational approaches to understand complex fluid phenomena, particularly those involving rotation, thermal effects, and turbulence. His research often bridges theoretical fluid dynamics with practical engineering applications.

His publication record shows consistent contributions to fluid dynamics journals, with recent work focusing on thermal effects in rotating annular systems, stratorotational instabilities, and advanced numerical methods. The articles demonstrate progression from fundamental flow instability studies toward more complex applications involving thermal gradients and deformable boundaries.
