12th Workshop on Synthetic Turbulence Models -

Organised by SIGs 42 - 14 - 35

3rd-4th July 2017, Université Paris-Ouest, Nanterre La Défense, France

“Synthetic flows for heat and mass transfer”

Université Paris-Ouest, Nanterre La Défense, France

Synthetic Modelling is widely used in various domains, including Lagrangian aspects in turbulence mixing/stirring, particle dispersion/clustering.The aims 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 applications to heat and mass transfer with contribution from Laboratoire Energétique Mécanique Electromagnétisme in Université Paris-Ouest.Interdisciplinary contributors are especially invited to contribute.

Audience:This conference on synthetic turbulence co-organised byERCOFTAC/SIG 42, SIG14 and SIG35 is open to anyone interested in flow, heat and mass transfer modellingand/or "synthetic turbulence" including (but not restricted to)Kinematic Simulation, (KS hereinafter).
More fundamental talks on particle dispersion in turbulent flows or fluid dynamics are also welcome.

Motivation:
KS is widely used in various domains, including Lagrangian aspects inturbulence mixing/stirring, particle dispersion/clustering, and last butnot least, aeroacoustics. Flow realisations with complete spatial, andsometime spatio-temporal, dependency, are generated via superposition ofrandom modes (mostly spatial, and sometime spatial and temporal,Fourier modes), with prescribed constraints such as: strictincompressibility (divergence-free velocity field at each point), highReynolds energy spectrum, ... Recent improvements consisted inincorporating linear dynamics, for instance in rotating and/orstably-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 invery different applications: inertial particle clustering as well as in aeroacoustics. Nevertheless, this issue was addressed in some referencepapers, and merits to be revisited in the light of new studies in progress.
A further goal of this conference is to bring people from differentdisciplines together. In particular recent emerging fractal approacheshave the potential to provide the framework for the construction of new synthetic turbulent flows. This workshop will also focus on potential application to heat and mass transfer with contribution from Laboratoire Energétique Mécanique Electromagnétisme in Université Paris-Ouest.
