Going back to Kolmogorov, there has been the paradigm in the more fundamental turbulence community of one universal state of homogeneous isotropic turbulence. In the last 15 years or so it has become more and more clear that this is not the case and that there can be several different states of turbulence, with transitions between these states. The transitions between the different states normally are of subcritical nature, just as the transition from laminar pipe or channel flow to turbulent pipe of channel flow. There, the origin of the subcritical nature is the nonnormality of the operator, combined with the nonlinearity of the Navier-Stokes equation. The nonnormality is intimately related to the local shear of the flow. All this also holds for turbulent flow, where one locally also has strong shear.

Multiphase flows are common in nature and engineering. Atmospheric flows often involve the dispersion of droplets or solid particulate matter (dust, sand, ice crystals in clouds); marine systems are populated by plankton, sediments or microplastics. Industrial applications of disperse flows include particle separators,filtration systems, atomisers and combustion devices, spray dryers, bubble columns; interfacial and free-surface flows are widespread in chemical and process industry.

Cet ouvrage présente les bases de la turbulence aux chercheurs en écologie marine, et les couplages de l’écologie marine avec la turbulence, aux chercheurs en turbulence provenant d’autres disciplines. Il s’adresse aux doctorants, jeunes chercheurs et chercheurs confirmés intéressés par ces deux sujets et leurs interactions.

The Leeds Institute for Fluid Dynamics is delighted to partner with the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge, the UK Fluids Network, and the Journal of Fluid Mechanics to deliver a regular webinar series on fluids-related topics.

On behalf of my fellow conveners, I would like to invite you to submit contributions to the Geophysical Fluid Dynamics (GFD) session at the AGU Annual Meeting 2026, which will be held in San Francisco (USA) from 7 to 11 December 2026. Please note that there is a strong possibility that this will be the last AGU Annual Meeting held in San Francisco for a decade, making this a particularly good opportunity to attend in person.This is a reference session for many scientists affiliated with the GDRs Mécanique des Fluides Géophysiques & Astrophysiques and Navier Stokes 2.00 and, as in previous years, we expect numerous abstract submissions from these communities.Please note that AGU and the Nonlinear Geophysics (NG) section, which hosts the GFD session, support the participation of students and early career scientists in the Annual Meeting through the AGU Honors Program, poster awards, and travel grants.

Nous proposons un sujet de thèse sur les transferts d’énergie dans les plasmas spatiaux turbulents, pour lequel nous recherchons un candidat / une candidate. La thèse s’inscrit à l’interface entre la physique des plasmas et l’étude de la turbulence dans l’héliosphère, avec un intérêt particulier pour les processus de cascade et de dissipation de l’énergie à différentes échelles.

We will investigate the interaction between weakly inhomogeneous turbu-lence and sedimenting particles which are larger than the smallest flow structures. The objectiveis to determine the influence of particle size and concentration on both the particle motion andthe fluid flow. The study, which will be carried out in collaboration with a partner team in Franceperforming laboratory experiments, can be expected to generate unprecedented data-sets al-lowing for new insight into long-standing problems.
