Wall-modelled large-eddy simulation of turbulent channel flow with unstable stratification
Li-Sheng Jiang, Ao Xu, Heng-Dong Xi
Unstable thermal stratification modifies near-wall momentum and heat transport, causing the mean velocity profile to depart from the classical logarithmic law and complicating wall…
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…
Revisit eddy viscosity in pressure-driven wall turbulence at high Reynolds number
Ben-Rui Xu, Ao Xu
We investigate eddy-viscosity distributions in pressure-driven wall turbulence for three canonical configurations: plane closed-channel flow, open-channel flow with a free-slip sur…
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 num…
