Introduction


Reacting and two
-
phase flows are found in a variety of practical systems (energy
generation, propulsion, chemical engineering, meteorology…)

but are still
associated with many open theoretical questions. In many cases DNS are
essential a
s a complement to experimental investigations in order to understand
the basic coupling processes controlling complex flows. However, Direct
Numerical Simulations have very specific, strict requirements, generally not widely
known to students or researcher
s familiar mostly with the standard, Reynolds
-
averaged approach. Furthermore, the accurate
numerical modelling of
reacting
and two
-
phase flows requires a variety of physical sub
-
models, which must be
carefully chosen in order to obtain a reliable numerical

description of real flows.

This Summer S
chool will focus on the t
heory, implementation and choice of model

in the
DNS

of reacting
and two
-
phase
flows
and is intended for researchers as well

as
code developers (
PhD students or R&D e
ngineers) interested in
understanding
and implementing
DNS

methods, or simply
in
acquiring a better background on the
topic

in order to assess its possible contribution to real problem solving
. The
instructors are
all
experts in DNS, numerical methods,

and associated physical
mod
els

and will present not only the various models and methods
most commonly
employed
but also implementation and efficiency issues
ranging from

basic
principles
to

state
-
of
-
the
-
art applications. The course will have
a
duration of 5 days
(full teaching progr
amme) plus two days of get
-
together, in order to foster
exchange and communication among participants, during and after the Summer
School.
