Prof Mathieu was a great scientist and one of the founding fathers of ERCOFTAC helping with establishing the organisation in 1988. Because of this he has remained an 'honorary president' of ERCOFTAC till his passing. He is remembered by his ERCOFTAC colleagues as a creative scientist, with a warm personality who contributed significantly to the early years of ERCOFTAC. His pioneering work that paved the way for SIG42. A full obituary will be published in the ERCOFTAC Bulletin later this year.

Audience:

This conference on synthetic turbulence co-organised by
ERCOFTAC/SIG 42 and SIG14 is open to anyone interested in flow, heat and mass transfer modelling
and/or "synthetic turbulence" including (but not restricted to)
Kinematic Simulation, (KS hereinafter). 

More fundamental talks on particle dispersion in turbulent flows or heat and mass transfer are also welcome.

Motivation:
KS is widely used in various domains, including Lagrangian aspects in turbulence mixing/stirring, particle dispersion/clustering. Flow realisations with complete spatial, and sometime spatio-temporal, dependency, are generated via superposition of random modes (mostly spatial, and sometime spatial and temporal, Fourier modes), with prescribed constraints such as: strict incompressibility (divergence-free velocity field at each point), high Reynolds energy spectrum, ... Recent improvements consisted in incorporating linear dynamics, for instance in rotating and/or stably-stratified flows, with possible easy generalisation to MHD flows, and perhaps to plasmas. KS for channel flows have also been validated.
However, the absence of "sweeping effects" in present conventional KS versions is identified as a major drawback in very different applications: inertial particle clustering as well as in aeroacoustics. Nevertheless, this issue was addressed in some reference papers, and merits to be revisited in the light of new studies in progress.
A further goal of this conference is to bring people from different disciplines together. In particular recent emerging fractal approaches have the potential to provide the framework for the construction of new synthetic turbulent flows. This workshop will also focus on potential application to flow through complex porous media and multiphase flows
Interdisciplinary contributors are especially invited to contribute.

A non-exhaustive list of related topics can be proposed as follows:
- Synthetic models of turbulence (KS and others), - Lagrangian aspects of turbulence,
- Vortex dynamics and structure formation,
- Particle dispersion/clustering,
- Muliphase multicomponent flows,
- Heat and mass transfer in complex flows (turbulence, Muliphase multicomponent flows ...) - Turbulent flows and multiscale (fractal) shapes, ...
- Flow in porous media. Participants (preliminary):
