Size-dependent transient nature of localized turbulence in transitional channel flow
Duo Xu, Baofang Song
It has been reported that a fully localized turbulent band in channel flow becomes sustained when the Reynolds number is above a threshold. Here we show evidences that turbulent ba…
Linear stability of channel flow with microgroove-type anisotropic superhydrophobic walls
Xueyan Zhai, Kaiwen Chen, Baofang Song
We study the temporal linear instability of channel flow subject to a tensorial slip boundary condition that models the slip effect induced by microgroove-type super-hydrophobic su…
A numerical study of the side-wall effects on turbulent bands in channel flow at transitional Reynolds numbers
Haoyang Wu, Baofang Song
We investigated the side-wall effects on turbulent bands in channel flow at transitional Reynolds numbers by direct numerical simulations using the open source spectral-element cod…
Direct numerical simulation of two-phase pipe flow: influence of the domain length on the flow regime
Carlos Plana, Baofang Song, Marc Avila
We perform direct numerical simulations of a kerosene-water mixture in pipe flow under realistic experimental conditions by solving the Cahn-Hilliard-Navier-Stokes equations. We co…
Trigger turbulent bands directly at low Reynolds numbers in channel flow using a moving-force technique
Baofang Song, Xiangkai Xiao
We show a method, for direct numerical simulations, to trigger and maintain turbulent bands directly at low Reynolds numbers in channel flow. The key is to impose a moving localise…
Nonlinear hydrodynamic instability and turbulence in pulsatile flow
Duo Xu, Atul Varshney, Xingyu Ma +4
Pulsating flows through tubular geometries are laminar provided that velocities are moderate. This in particular is also believed to apply to cardiovascular flows where inertial fo…
