Between Statistical Patterns and Coherent motions - On Strategies for Flow-Structure Identification

Jochen Kriegseis - Karlsruhe Institute of Technology (KIT)

Between Statistical Patterns and Coherent motions - On Strategies for Flow-Structure Identification

Vendredi 20 Oct 2017 , ECL, bât W1 salle 104

Formation, persistence and dynamics of vortical flow structures predominate various flow scenarios in nature and technical application. Documented efforts to characterize these structures go back (...)

Transition to turbulence in plane Couette flow

Romain Monchaux - ENSTA-ParisTech, Paris, France

Transition to turbulence in plane Couette flow

Vendredi 17 Nov 2017, 11h, ECL, bât W1 Amphi 1bis

We experimentally and numerically investigate the temporal aspects of turbulent spot spreading in a plane Couette flow for transitional Reynolds number between 300 and 450. Spot growth rate, spot (...)

 Measuring the relevance of waves in turbulent flows

Pablo Mininni, Departamento de Fisica, Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires

Measuring the relevance of waves in turbulent flows

Vendredi 24 Nov 2017, 11h, ECL, Amphi 203

Turbulence is ubiquitous in a large variety of flows, from geophysical and astrophysical to industrial flows. Given their complexity, turbulent flows are often studied by combining numerical, (...)
