Why this conference?
Transport phenomena are relevant in several fields, both for
applications and for fundamental research. Basically, the problem can
be divided in two large classes:
I- Macroscopic scale transport
II- Micro/nano transport
In class I we include the transport of inert and reacting substances
which is of great relevance on the fundamental level (chaotic
dynamics, Markovian processes) as well as for applications
(geophysics, combustion). This problem has been often approached by
means of continuous models (partial derivative equations) and
restricting the focus on the asymptotic dynamics. Many real situations
require non-asymptotic phenomena and discrete models to be considered
(e.g., in the case of reacting particles which, advected by the fluid,
change their "color" as consequence of the interaction with
neighbouring particles). At the same time, it is important to take
into account the problem of transport of impurities of finite size and
of different density with respect to that of the advecting
fluid. These situations, indeed, are commonly encountered in the study
of environmental problems, or when trying to improve industrial
processes, and are also essential in the understanding of important
physical problems (e.g. the formation of rain droplet). From the
theoretical point of view new phenomena appear, such as the formation
of "cluster" of particles and preferential concentration.
The micro/nano transport is also a relevant problem with a great
impact on applications. In this domain, the Knudsen number (ratio
between mean free path and typical system size) is high, making
kinetic theory inapplicable, particles are practically independent and
the problem can be studied in the framework of dynamical systems. An
important theoretical challenge is related to the difficulties of
using standard transport theories (e.g. the Fick equation), since an
asymptotic regime (in time) is usually not reached and/or diffusion is
anomalous.
In the last decade an increasing community of researchers had to deal
with anomalous transport while trying to tackle problems in basic
science as well as in applications and experiments. Actually, beyond
its conceptual interest, anomalous transport can provide an effective
tool for analyzing and understanding many practical problems like
transport in nanosystems.
The main goal of this school/conference is surveying the relevance
of non standard transport in various research domains ranging from
mathematics to geophysics and nanosystems.
The school/conference aims also at collecting
scientists from different research areas sharing a common interest
for diffusion and transport.
