MINISYMPOSIA

Biomechanics of swimming and flying
and bio-inspired propulsion
 
Francisco Huera-Huarte, Universitat Rovira i Virgili (ES)
Megan Leftwich, George Washington University (US)
We have seen in the last decades an increasing interest in the broad field of bio-locomotion and bio-inspired propulsion and in particular in all related to swimming and flying.We would like to bring together a broad scientific and multidisciplinary audience working in the intersection of biological, physical and engineering sciences, with numerical, theoretical or experimental approaches.
Topics may include but are not limited to: Swimming and underwater dynamics, flying and aerial locomotion, fluid-structure interaction phenomena, biomimetics and bio-inspired applications fluid dynamics, cooperative behaviour and collective dynamics.
Flows in porous media
 
Wim Paul Breugem, TU Delft (NL)
Francesco Zonta, TU Wien (AT)
The aim of this minisymposium is to review and discuss the current understanding of transport phenomena through porous media and through/along porous interfaces in environmental, industrial and biological applications. We welcome contributions from experimental, numerical and theoretical studies on topics including but not limited to: single and multiphase flow, hydrodynamic stability, convection, dispersion, reactive flows, isotropic and anisotropic porous media, dynamics of porous interfaces, wetting phenomena, flow at the pore scale and pore-elastic (deformable) media.
Fluid mechanics of particles at interfaces and surfactants
 
Lorenzo Botto, Queen Mary University of London (UK)
Recent interest in the dynamics of solid particles embedded in fluid interfaces has opened new opportunities for fluid mechanics research. This mini-symposium aims to bring together researchers interested in molecular surfactants and surface active particles, their transport to and in fluid interfaces, interfacial rheology, and interfacial effects on the dynamics of multiphase flows. In addition to fluid mechanicists, we welcome experts in physical chemistry with an interest in colloidal or molecular hydrodynamics. Some topics of interest are: interaction of particles with drops and bubbles, particle & surfactant transport in thin liquid films and threads, Marangoni effects, stabilization of foams and emulsions, particle-interface interactions near contact lines, and three-phase flows with particles.
Magnetic fluids
Stefan Odenbach, TU Dresden (DE)
Suspensions of magnetic particles show normal liquid behaviour coupled with superparamagnetic properties enabling a magnetic control of their properties and flows. This magnetic control, which can be achieved already with weak magnetic fields, enables fascinating possibilities in fluid mechanics as well as a wide range of applications. It will be the focus of the minisymposium to discuss recent developments in magnetic fluid research covering all major fields of research in this area – from heat and mass transfer and magnetic flow control over rheological properties towards all kind of applications of magnetic fluids.
Perturbation techniques in fluid mechanics
Stefan Braun, TU Wien (AT)
Helen Wilson, University College London (UK),
Bernhard Scheichl, TU Wien (AT)
The development of formal asymptotic methods has been largely driven by the ubiquitous presence of small or large non-dimensional key groups in the basic equations governing the motion of fluids, and closely related mechanisms as heat and mass transfer. Due to their unique strength and versatility, they enable a surprisingly deep understanding of various phenomena, including e.g. high-Reynolds-number flows: external and internal, laminar, transitional, and turbulent ones; gas dynamics; hydrodynamic stability; free-surface flows, including waves, and capillary flows; geophysical flows; and even complex fluids and multi-phase flows. We invite scientists in the above and other fields to present their progress using perturbation techniques. We welcome work on problems which arise in industry; those with practical impact; and open theoretical problems. In terms of methodology, we expect work which spans both analytical and numerical approaches to asymptotic analysis, and also comparison with results obtained by experiments and full simulation.
Recent advances in understanding of edge flame dynamics
 
Antonio Luis Sanchez, University of California, San Diego (US)
This minisymposium will review recent progress made in connection with the understanding of the structure, propagation velocity, and dynamics of edge flames, their interactions with the flow field, and their role in the ignition, liftoff, and extinction of laminar and turbulent flames. Controlled experiments in strained mixing layers, numerical simulations, and asymptotic analyses will all be addressed. The work is intended to advance fundamental understanding and predictive capabilities of reactive flows in practical combustion applications.
Sedimentary flows and patterns
 
Markus Uhlmann, KIT (DE)
Sivaramakrishnan Balachandar, University of Florida (US)
The focus of the Mini-Symposium will be on the following aspects related to fluid-mediated sediment dynamics:
  • Formation process of sediment bedforms.
  • Interaction of bedforms with turbulent flow.
  • Evolution of bedforms on large (temporal and spatial) scales.
At this event we would like to bring together researchers working with different methodologies (theoretical, experimental and numerical), in order to allow for a comprehensive dialogue. It is our hope that this exchange will lead to new ideas and ultimately help to advance the field.
