About:
Turbulent flows are ubiquitous in everyday life and in engineering or industrial applications. Research in this field is by nature interdisciplinary, as an interplay between numerical simulation, experiment and data analysis is required to obtain sufficient information of the structure and dynamics of such flows and thus their impact in industry and engineering – understanding and achieving drag reduction is one of many examples. As numerical data and analysis techniques provide information not attainable by experiment, the application and development of methods from within Applied Mathematics – in particular computational approaches developed for applied dynamical systems – are central to the field. The meeting will be focussed on the application and development of such methods to a particular type of turbulence that occurs in flows of viscoelastic fluids, in close discussion with experimentalists.
