15-17 September 2025:: Euromech colloquium n°658 “Coherent structures and instabilities in transitional and turbulent wall-bounded flows”

Posted by on 23 March 2025 Comments Off on 15-17 September 2025:: Euromech colloquium n°658 “Coherent structures and instabilities in transitional and turbulent wall-bounded flows”

 

Euromech colloquium n°658 entitled “Coherent structures and instabilities in transitional and
turbulent wall-bounded flows” (https://658.euromech.org/),
organised by Stefania Cherubini and Jean-Christophe Robinet, to be held on 15-17 September 2025 in the sunny medieval city of Bari, Italy.

The objective of this conference is to provide an international forum for discussing
the latest developments in instability and coherent structures
computations for both transitional and fully turbulent flows.

The colloquium will bring together researchers studying the rise and
development of instability mechanisms leading to three-dimensional flow structures in
different shear flows, with the aim of trying to find some common features between
the structures triggering or sustaining turbulence in such different cases.
The deep knowledge of exact coherent structures in parallel flows, as well as
the recent possibility of performing instability analysis on complex three-dimensional
or fully turbulent flows begin to make possible the achievement of such an ambitious goal.

Main topics are:
—————-
– Modal & non modal instabilities
– Turbulence dynamics
– Receptivity, sensitivity
– Transition to turbulence
– Coherent structures
– Bifurcations and continuation methods

Important dates are:

Posted by on 6 February 2025 Comments Off on 27-30 July 2025:: iTi Conference on Turbulence XI in Bertinoro, Italy

Dear Colleague,

We are pleased to invite you to attend the iTi Conference on Turbulence XI in Bertinoro, Italy, July 27-30, 2025.
This year, the iTi conference will be combined with a one-day workshop organized by Gabriele Bellani (Università di Bologna) and Gioacchino Cafiero (Politecnico di Torino) entitled “Structure and control of wall-bounded turbulent flows” held on July 27, 2025. The aim of the workshop is to foster discussions on the latest advances and solutions for the control of turbulent boundary layers. In the spirit of iTi, the workshop promotes an interdisciplinary view of the problem including theoretical, experimental and numerical approaches. Two international keynote speakers, Marios Kotsonis (TU Delft, NL) and Peter Schmid (KAUST, Saudi Arabia) will give an overview of the current challenges and the most promising tools for the control of wall-bounded flows. Workshop attendance is optional and must be specified upon registration. Contributions to this workshop will be part of the iTi conference proceedings.
List of iTi conference key-note speakers:
Koji Fukagata (Keio University, Japan)
Susanne Horn (Coventry University, UK)
Alessandra Lanotte (CNR, Italy)
Joachim Peinke (University of Oldenburg, Germany)
Christina Vanderwel (University of Southampton, UK)
Dates and deadlines:
Abstract submission:                                      February 20, 2025 [already extended!]
Response/accepting the contribution:               March 2, 2025
Early registration for Workshop/Conference:     May 4, 2025
Late registration for Workshop/Conference:      July 26, 2025
Essential information is available on the conference website https://www.fdy.tu-darmstadt.de/iti/itihome_2.en.jsp, where also LaTeX and Word templates for the preparation of the abstracts are available. Further information for the conference proceedings will be made available very soon. In this regard, we would like to announce that we decided – after 20 years and 10 volumes of Progress in Turbulence – to switch from Springer to IOP for our conference proceedings, due to wishes of many participants to offer open access for all contributions and a timelier publication schedule.
We are very happy to welcome you in Bertinoro.
Best wishes

Ph.D. position in Numerical Simulation of Magnetohydrodynamic (MHD) flows in rectangular ducts with flow control

Posted by on 9 December 2024 Comments Off on Ph.D. position in Numerical Simulation of Magnetohydrodynamic (MHD) flows in rectangular ducts with flow control

from Prof. J. Schumacher and Dr. D. Krasnov at TU Ilmenau, Germany

INTRODUCTION: The Fluid Mechanics group of Prof. J. Schumacher at the Institute of Thermodynamics and Fluid Mechanics at TU Ilmenau has a broad experience and research interest in theoretical and numerical studies of turbulent flows, thermal convection and magnetohydrodynamic flows in channels and ducts as well as the development of corresponding reduced order models. We have developed a family of in-house flows solvers for performing direct numerical simulations (DNS) of turbulent flows at high-performance parallel supercomputers. The group participates in European high-performance computing initiative and is working in close collaboration with the German supercomputing facilities in Garching and Jülich. Over the past 20 years we have also established strong and active ties within the turbulence, convection and MHD communities world-wide.

PROJECT DESCRIPTION: A new research project, which is funded by the Deutsche Forschungsgemeinschaft (DFG), combines numerical studies in MHD flows with data-driven surrogate model development to control and optimize the heat and momentum transfer in these flows. The project is a collaborative effort between TU Ilmenau (Dr. D. Krasnov andProf. J. Schumacher, Mechanical Engineering) and TU Dortmund (Prof. S. Peitz, Computer Science).

More detailed, the project aims at studying the dynamics of liquid-metal flows in cooling blankets of fusion reactors. Liquid-metal blankets are an essential part of the TOKAMAK-type of fusion reactors, serving two important purposes: (i) withdrawing a huge amount of heat, produced by the plasma core and (ii) breeding of tritium fuel. Flows in such systems are exposed both to very strong thermal loads (due to neutron fluxes) and very strong magnetic fields (confinement of the plasma core). As a result, the overall flow dynamics is quite far from the usual hydrodynamic turbulence – the flows in blankets are known to exhibit highly intermittent states, anisotropic quasi-2D structures and random outbursts of excessively strong temperature fluctuations. In the project we will study such non-trivial dynamics and will explore novel promising concepts of their control by vortex promoters (e.g., flat jets) supplied at the duct entry. The ultimate goal is to embed an active control, capable of optimizing the heat and mass transport properties within a wide range of the parameter space. Therefore, the project is composed of two major topical and tightly linked parts – simulations of liquid metal flows and data analysis/development by machine learning. This will require active involvement of both parties, including regular research exchange and visits.

RESPONSIBILITIES: The main task of the Ph.D. student at TU Ilmenau is to perform simulations with an in-house Finite-Difference flow solver, to analyze the results, explore the mechanisms of magneto-convective instabilities and the associated flow structures. It will also include the development of data-driven models. Other responsibilities include contribution to writing research papers, reports and computing time proposals. The candidate will also be involved with a small load in the teaching (classes on basic fluid dynamics level) and in co-supervision of the local students at Master level.

PROFILE: Candidates are expected to have completed M.Sc. degree in one of the following programs: Mechanical or Aerospace Engineering, Physics, or Applied Mathematics.Experience in fluid mechanics with an emphasis on numerical simulations of unsteady flows are highly welcomed, but not compulsory. The same holds for skills in High-Performance Computing, parallel programming, or flow visualization. For applications or further questions on the opening please contact
