Navier-Stokes solver using Green's functions I: channel flow and plane Couette flow
Navier-Stokes solver Green's functions channel flow plane Couette flow Fluid Dynamics
2012/5/31
Numerical solvers of the incompressible Navier-Stokes equations have reproduced turbulence phenomena such as the law of the wall, the dependence of turbulence intensities on the Reynolds number, and e...
Absolute linear instability in laminar and turbulent gas/liquid two-layer channel flow
Absolute linear instability laminar and turbulent gas/liquid two-layer channel flow Fluid Dynamics
2012/4/20
We study two-phase stratified flow where the bottom layer is a thin laminar liquid and the upper layer is a fully-developed gas flow. The gas flow can be laminar or turbulent. To determine the boundar...
Statistics of the Energy Dissipation Rate and Local Enstrophy in Turbulent Channel Flow
Turbulent channel flows, turbulent shear flows, energy dissipation rate, enstrophy

Using high-resolution direct numerical simulations, the height and Reynolds number dependence of higher-order statistics of the energy dissipation rate and local enstrophy are examined in incompressib...
A numerical study on the free-surface channel flow over a bottom obstacle
open channel flow undular hydraulic jump
2010/3/11
This paper presents the results of a numerical study on a two-dimensional freesurface channel flow over a bottom obstacle. Of main interest is the capability of commercial CFD codes to solve such prob...
