Log-linear law of the mean streamwise velocity in turbulent boundary layers with moderate adverse pressure gradients
Fuzhou Lyu, Lihao Zhao, Weixi Huang +1
An essential feature of canonical zero-pressure-gradient (ZPG) turbulent boundary layers (TBLs) is that the mean streamwise velocity exhibits a logarithmic dependence on the wall-n…

Prolate spheroids settling in a quiescent fluid: clustering, microstructures and collisions
Xinyu Jiang, Chunxiao Xu, Lihao Zhao
In this study, we investigate the sedimentation of prolate spheroids in a quiescent fluid by means of the particle-resolved direct numerical simulation. With the increase of the pa…

Interactions between the near-wall turbulent structures and heavy particles in compressible turbulent boundary layers
Ming Yu, Lihao Zhao, Yibin Du +2
In the present study, we conduct direct numerical simulations to investigate the near-wall dynamics of compressible turbulent boundary layers at the free-stream Mach number of 6 la…
