Welcome to the STRATA Research Group
Supercomputing for Stratified Turbulence Research Advancing Theory and Application

The objective of this group is to generate and analyze fully-resolved direct numerical simulations of stratified turbulence, across a variety of flow configurations and parameters, in order to better understand fundamental turbulent processes influenced by buoyancy and their importance to geophysical, industrial, and environmental applications.

We gratefully acknowledge support from the INCITE Leadership Computing Program (U.S. Department of Energy) and the High Performance Computing Modernization Program (U.S. Department of Defense), through which this work has been enabled.

Current Research Themes

  • Exascale computing to resolve stratified turbulent flows in previously-inaccessible regions of parameter space
  • Probing coupling between large and small-scale flow features to inform reduced-order modelling
  • Development of data-driven and machine-learning techniques to extra physical insight from petabyte-scale datasets

Datasets

We are developing a database of stratified turbulence simulations, and associated codes for analysis. Our data spans a variety of:

  • Forcing schemes: steady-state vortically-forced and shear-driven; time-evolving (unforced) flows
  • Parameters: buoyancy-Reynolds ($Re_b$), Froude ($Fr$), Prandtl ($Pr$) numbers
