CSP - Euromech/Ercoftac Colloquium 589 : TURBULENT CASCADE II ( concerning turbulent cascades in the complex conditions)

Abstract

Most of environmental and industrial flows are turbulent, and in turbulence the conceptof turbulent cascade is the key idea. From t""he classical works of Taylor, Kolmogorov,Heisenberg, Onsager on how the statistical universality may arise at small scales, thisco""ncept continues to evoke a very considerable interest. In recent decades, newphysical ideas free from classical assumptions, has be""en imbedded in the concept ofturbulent cascade, with support by experiments and numerical simulations. Thequestion on why do the c""lassical -5/3 Kolmogorov scaling appears in situations of 3Dturbulent flows, in which classical assumptions are not fulfilled, has"" motivated manydiscussions on non-equilibrium cascade during EUROMECH/ERCOFTAC Colloquium~Turbulent Cascades I~ in Lille, France."" The motivation for this current EUROMECHColloquium 589 ""Turbulent Cascades II"" is to discuss the manifestation of the turbulentca""scades in more complex conditions, such as two-phase flows and compressibleflows. The Colloquium will be organized by the LMFA (Eco"le Centrale of Lyon)together with the Physics Laboratory (Ecole Normale of Lyon) and LEGI (Grenoble).It will be held on December 5"-7, 2017 at the campus of the Ecole Centrale, Lyon.The primary focus of the colloquium is to discuss about turbulent cascades in th""epresence of the gas-liquid interface, more specifically on the role of the surfacetension, and the interface waves in immiscible" two-fluid turbulent systems. Thequestions concerning the interactions of turbulence with the liquid droplet wake in thegas phase" and with the atomization process becomes pertinent. Furthermore,discussions on turbulent cascades in the presence of immerged soli"d inertial particleswill take place. The aim would be to understand the impact of particles larger thanKolmogorov~s scales on the" turbulent cascade. Also, how the clusters of particlesmight induce the turbulence will be discussed.Another very essential object""ive of this Colloquium is to consider the effects of shear,rotation, body forces, and magnetohydrodynamic coupling in both Eulerian" andLagrangian frameworks. The invited scientific experts from leading weatherforecasting organizations across Europe will provide" insights on application of theseconcepts to atmospheric and oceanic physics. In addition, we wish to extend thescientific scope b"y including discussions on turbulent cascades in the non-Newtonianflows and compressible flows. By bringing together researchers in" variousbackgrounds, this colloquium will attempt to clarify certain questions and motivatefurther studies. The expected audience"" in this Colloquium is of about 60 externalparticipants, plus a score of invited speakers. The Colloquium will be open for freeatt""endance to students and junior researchers, although we highly expect to draw aninternational crowd of researchers. Further announc"ements will be presented on thededicated webpage: https://turb-cascades-2.sciencesconf.org
