Workshop on Coherent Structures for Turbulence Modeling

In the late 80s and early 90s, with the growth of LES, and increased interest in coherent structure identification, including Q criterion and POD methods, there was a general anticipation that turbulent coherent structures would play a key role in modeling and prediction.  With certain very specific exceptions, that promise never materialized, the mathematics of coherent structures has not been incorporated in modeling, and the modeling and coherent structures communities have largely diverged.  Now, thirty years later, with important advances on both sides, most significantly the discovery and development in the field of exact coherent structures, perhaps it is time to revisit the connection between modeling and coherent structures.

 This conference is intended to bring together experts and interested parties from both communities to examine the following questions:

·      What are the implications of our current understanding of coherent structures for modeling turbulence?

·      Can coherent structures be incorporated into turbulence modeling in a mathematical way?

·      Might our understanding of coherent structures change what we ask our models to predict?

Data-driven techniques and ML may (or may not) be an important tool as part of this, but will not be a primary focus of this conference.
