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.
