About
IUTAM TRANSITION 2024
Transition from laminar to turbulent flow has attracted researchers since the work by Osborne Reynolds at the end of the 19:th century and is still an evolving and vibrant research field, both regarding the nature of various flow instabilities and the relation to the intrinsic mechanisms of turbulence generation as well as being important for many engineering applications. For the advancement of research of turbulence "embryology," nine IUTAM Symposia have so far been held since the first in Stuttgart 1979, followed every five years by Novosibirsk 1984, Toulouse 1989, Sendai 1994, Sedona 1999, Bangalore 2004, Stockholm 2009, Rio de Janeiro 2014 and London 2019. The coming IUTAM Symposium on Laminar-Turbulent transition will be held in 2024 in Nagano, Japan to build on the progress made over the past 45 years. The main topics will be, but not limited to:
- Boundary layer transition
- Flow instability
- Transition in engineering applications
- Control of transition
- Low Reynolds number turbulence or turbulent/laminar flow
- Turbulence generation in transitional and developing turbulent flows
We welcome theoretical, experimental, numerical, as well as AI research on these topics. We are looking forward to your participation and enthusiastic discussions among the participants.

Keynote Speakers
P. Henrik Alfredsson
P. Henrik Alfredsson obtained his doctoral degree in 1983 from KTH Royal Institute of Technology, Sweden, with a thesis titled “Experimental studies of turbulent channel flow”. He continued research on wall-bounded turbulence but soon focussed on various stability and transition problems, such as turbulent spots in channel flows, and instabilities in plane and curved channel flows under spanwise system rotation. The planning of a new low-turbulence wind tunnel at KTH started in 1986, which he together with his colleague A.V. Johansson inaugurated in 1990 (later named the MTL – Minimum Turbulence Level – wind tunnel). The wind tunnel has among other things been used for studies on Tollmien-Schlichting waves as well as the influence of free-stream turbulence on transition. In 1989, a unique – at that time – plane Couette flow apparatus was designed for the study of turbulent spots and transition to turbulence. Later this apparatus was placed on a rotating table to allow investigations of the influence of the Coriolis force on flow stability and turbulence. Around 2007 he started collaborating with R.J. Lingwood on the stability of flow over rotating disks, which has subsequently expanded to also include the flow over broad and slender cones. Other areas of interest have been wind-turbine wakes, separation flow control, and IC-engine related fluid mechanics. In 1986, he became “extra” professor at KTH, in 1989 full professor in fluid physics and was adjunct professor at II Facolta di Ingegneria, Universita di Bologna between 2007 and 2017. He served as the Dean of the Faculty of KTH between 1999 and 2003 and since 2019 is professor emeritus at KTH. He was elected as a fellow of the American Physical Society, Division of Fluid Dynamics, in 2012. Together with students and colleagues, he has contributed to more than 140 papers in peer-reviewed journals.
Georgios Rigas
Dr. Georgios Rigas is a Senior Lecturer in the Department of Aeronautics at Imperial College London. Before joining IC in 2019, he was a Postdoctoral Scholar at Caltech and the University of Cambridge. He received his Ph.D. in Aeronautical Engineering from Imperial College in 2015. He serves as an early Career member of the PRF editorial board.
His work is focused on the development of techniques to improve the efficiency of fluid-based systems, including wall bounded flows and wakes in transitional and turbulent regimes. He is particularly interested in the development reduced order models, data-driven techniques and the experimental wind tunnel implementation of flow control approaches in real time.
He leads a joint Imperial College-CNRS-ONERA project on Reduced order Modelling using Machine Learning techniques and the Special Interest Group on 'Flow Instability, Modelling, and Control' within the UK Fluid Network. His current work is funded by US AFOSR on the development of transition prediction and control tools for high-speed flows and the UK Research and Innovation (UKRI) on AI for Net Zero.

His main lines of research include instability and transition of boundary-layer and separated flows, modeling and prediction of high-speed jet noise and slat aero-acoustics.
Takahiro Tsukahara
Takahiro Tsukahara is a Professor in the Department of Mechanical and Aerospace Engineering at Tokyo University of Science (TUS). He was born in 1980, and received his PhD in Engineering from TUS in 2007. After working as a Research Fellow of JSPS (Japan Society for the Promotion of Science) and as a visiting researcher at KTH (Royal Institutive of Technology, Sweden), he has been a faculty member in the Department of Mechanical Engineering at TUS, first as an Assistant Professor (2008-2013), later a Lecturer (2013-2017), an Associate Professor (2017-2022), and currently a full Professor (2022-present). In 2011, he was a visiting researcher at the Technical University of Darmstadt. His research employs direct numerical simulations to study subcritical transitions and heat transfers in wall-bounded shear flows of Newtonian and viscoelastic fluids. His main research interests are on flow instability, wall turbulence, drag reduction, elasto-inertial turbulence, scalar transport, interfacial flow, blood flow, and machine learning.
