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…
Self-critical machine-learning wall-modeled LES for external aerodynamics
Adrián Lozano-Durán, Hyunji Jane Bae
The prediction of aircraft aerodynamic quantities of interest remains among the most pressing challenges for computational fluid dynamics. The aircraft aerodynamics are inherently…
DNS-aided explicitly filtered LES
H. Jane Bae, Adrián Lozano-Durán
The equations for LES are formally derived by low-pass filtering the NS equations with the effect of the small scales on the larger ones captured by a SGS model. However, it is kno…
