Triggering of extreme events and coherent-structure modulation in wall-turbulence under cyclostationary forces
Ao Xu, Yun-Qian Bi, Heng-Dong Xi
Atmospheric gusts expose wall-bounded turbulence to severe unsteady forcing, triggering complex non-equilibrium dynamics and extreme aerodynamic loads. In this study, direct numeri…
Learning to traverse convective flows at moderate to high Rayleigh numbers
Ao Xu, Hua-Lin Wu, Ben-Rui Xu +1
We study the navigation of a self-propelled inertial particle in two-dimensional Rayleigh-Bénard convection at Prandtl number and cell aspect ratio for Rayleigh n…
Super-resolution reconstruction of turbulent flows from a single Lagrangian trajectory
Hua-Lin Wu, Ao Xu, Heng-Dong Xi
We studied the reconstruction of turbulent flow fields from trajectory data recorded by actively migrating Lagrangian agents. We propose a deep-learning model, track-to-flow (T2F),…
Velocity dip in turbulent mixed convection of an open Poiseuille-Rayleigh-Bénard channel
Ben-Rui Xu, Ao Xu, Heng-Dong Xi
We study the emergence of a velocity-dip phenomenon in turbulent mixed convection in open Poiseuille-Rayleigh-Bénard (PRB) channels with a free-slip upper boundary. Three-dimensio…
