Symposium outlineInterfacial mixing and transport control a broad variety
of phenomena in fluids and materials, in nature and technology, over celestial to
atomistic scales. Examples include fusion and supernovae, planetary
convection and reactive and super-critical fluids, material transformation
under impact, colloidal assembly, wetting and adhesion, and turbulence and
turbulent mixing. Addressing the societal challenges posed by alternative
energy sources, efficient use of non-renewable resources, purification of water
and development of reliable diagnostics and therapeutics in medicine, requires
a better understanding of non-equilibrium dynamics.
Interfacial transport and mixing are non-equilibrium
processes coupling kinetic to meso- and macroscopic scales. Their dynamics
often involve sharp changes of vector and scalar fields, and may also include
strong accelerations and shocks, radiation transport and chemical reactions,
diffusion of species and electric charges, among other effects. Interfacial
transport and mixing are inhomogeneous, anisotropic, non-local, and statistically
unsteady. At macroscopic scales, their spectral and invariant properties
differ substantially from those of canonical turbulence. At atomistic and
meso-scales, the non-equilibrium dynamics depart dramatically from the standard
scenario given by Gibbs ensemble averages and the quasi-static Boltzmann
equation. At the same time, non-equilibrium transport may lead to
self-organization and order, thus offering new opportunities for flow diagnostics
and control. Capturing properties of interfaces and mixing can aid better
understanding of the fundamental of Eulerian and Lagrangian dynamics, and developing
methods of control of non-equilibrium transport in nature and technology.
Significant success has been recently achieved in
understanding of interfacial transport and mixing on the sides of theoretical
analysis, large-scale numerical simulations, laboratory experiments, and
technology development. This success opens new opportunities for studies
of fundamentals of non-equilibrium dynamics across the scales, and for developing
a unified description of particles and fields on the basis of synergy of
experiment, theory and numerics. This is the right moment to apply the
fundamentals of non-equilibrium transport for addressing contemporary
challenges of modern science, technology and society, including energy,
environment and health care. Alternative energy sources, efficient use of
non-renewable resources, purification of water and development of reliable
diagnostics and therapeutics in medicine - addressing these challenges requires
the in–depth understanding of non-equilibrium dynamics, and the strong
interplay of ideas and approaches from the interdisciplinary areas of research.
The symposium is focused on mechanics and hydrodynamic aspects of interfacial transport and mixing that
couples kinetic to macroscopic scales.
It provides the opportunity to bring together scientists
from different areas of fluid dynamics, applied mathematics,
statistics, chemistry and material science. The symposium is structured
to encourage participants’ interactions with experts from
various fields to motivate the discussions of rigorous mathematical
issues, theoretical approaches and state-of-the-art numerical
simulations along with advanced experimental techniques and
technological applications. Participants include experts and
researchers at experienced and early stages of their careers from
academia, national laboratories and industry, and graduate students
from national and international communities. The organizers expect the
symposium to explore and assess the state-of-the-art in the
non-equilibrium transport, and to chart new directions of the
interdisciplinary research for the future.
