Wavelet Synthetic Turbulence

Motivation:
KS is widely used in various domains, including Lagrangian aspects in turbulence mixing/stirring, particle dispersion/clustering, and last but not least, aeroacoustics. Flow realisations with complete spatial, and sometime spatio-temporal, dependency, are generated via superposition ofrandom 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 inincorporating 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 invery 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. Interdisciplinary contributors are especially invited to contribute.

Travel and Accommodation:

Some of the hotels are close to the city center but unfortunately, none of them are very close to LSTM which locate in south part of Erlangen and about 3-5 km far from city center. However, the bus connections are very convenient in Erlangen. Some hotels in Erlangen
