Numerical simulations of fluid flows which accurately capture eddying motions is now arguably the most used tool in research on transitional and turbulent flows. The physical complexity of simulations continues to increase with current focus on algorithms for turbulence simulations in complex geometry, treatment of the interaction with deformable surfaces, modeling of sub-scale transport processes, and hierarchic modeling of multi-phase and reacting flows. Theoretical advances combining local and global stability analysis, computation of flow receptivity to free-stream disturbances, control forcing and other variations in boundary conditions, as well as advances in data-analysis and reduced-order modeling continue to enrich the understanding of flow physics and its modeling. Computational models have also opened new approaches to study and control complex fluid flows. Variants of governing equations or boundary conditions, where selected physical processes are enhanced or suppressed to reveal the critical dynamics and studies of flow-control where specific actuation is applied to improve an overall figure of merit, such as drag reduction, separation control and noise reduction are of current interest.

   This IUTAM Symposium on advances in computation, modeling and control of transitional and turbulent flows aims to bring together renowned experts from fluid dynamics, computational science, dynamical systems and control to share results from the latest developments in the field and to foster further progress by interaction and exchange of ideas.
