SIG: SIG42 Synthetic models in turbulence; SIG14 Stratified and Rotating Flows
Please submit a brief abstract to F.Nicolleau@sheffield.ac.uk preferably in latex but other formats will be fine as well.
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.
Synthetic models are widely used in various domains, including Lagrangian aspects in turbulence mixing/stirring, particle dispersion/clustering (KS). 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 optimisation methods used in mathematics to generate synthetic fields.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 and field reconstruction methods 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.
