A local dynamic gradient Smagorinsky model for large-eddy simulation
Wybe Rozema, H. Jane Bae, Roel W. C. P. Verstappen
This paper proposes a local dynamic model for large-eddy simulation (LES) without averaging in homogeneous directions. It is demonstrated that the widely-used dynamic Smagorinsky m…
Scientific multi-agent reinforcement learning for wall-models of turbulent flows
H. Jane Bae, Petros Koumoutsakos
The predictive capabilities of turbulent flow simulations, critical for aerodynamic design and weather prediction, hinge on the choice of turbulence models. The abundance of data f…
Life-cycle of streaks in the buffer layer of wall-bounded turbulence
H. Jane Bae, Myoungkyu Lee
Streaks in the buffer layer of wall-bounded turbulence are tracked in time to study their life-cycle. Spatially and temporally resolved direct numerical simulation data is used to…
Resolvent analysis of stratification effects on wall-bounded shear flows
M. A. Ahmed, H. J. Bae, A. F. Thompson +1
The interaction between shear driven turbulence and stratification is a key process in a wide array of geophysical flows with spatio-temporal scales that span many orders of magnit…
