A Method for Extracting Stream Channel Flow Paths from LiDAR Point Cloud Data
LiDAR Point Cloud Streams
2015/8/14
Traditional methods of delineating stream channel networks use gridded raster elevation data. Direct use of LiDAR point clouds, without first creating a raster or grid, could improve efficiency and ac...

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
2011/9/6
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...
Statistics of polymer extensions in turbulent channel flow
Statistics of polymer extensions turbulent channel flow
2010/11/17
We present direct numerical simulations~(DNSs) of turbulent channel flow with passive Lagrangian polymers. To understand the polymer behavior we investigate the behavior of infinitesimal line elements...
Recurrence in 2D Inviscid Channel Flow
Recurrence inviscid channel flow kinetic energy enstrophy compact embedding
2010/12/1
I will prove a recurrence theorem which says that any Hs (s > 2)solution to the 2D inviscid channel flow returns repeatedly to an arbitrarily small H0 neighborhood. Periodic boundary condition is impo...
On Three-Dimensionality of Turbulent Buoyant Channel Flow
Buoyancy Channel flow Turbulence
2010/1/14
A three-dimensional buoyancy-driven turbulent boundary layer is generated in fully developed turbulent channel flow.
Setting the buoyancy forces perpendicular to the mean flow direction and using hig...
THREE-DIMENSIONAL STABILITY ANALYSIS OF OPEN CHANNEL FLOW OVER AN ERODIBLE BED
THREE-DIMENSIONAL STABILITY ANALYSIS OPEN CHANNEL FLOW ERODIBLE BED
2009/10/29
The formation oP ripples and dunes (lower range bed waves) is assumed to
be related to the transport of sediment as bed load. From the present
theory it is concluded that the formation of the upper ...
Rotating Shocks in a Separated Laboratory Channel Flow
hydraulic jump rotating channel Separated Laboratory Channel Flow
2009/1/7
Laboratory studies of the effects of wall separation on a hydraulic jump in a rotating channel of rectangular cross section are described. Separation is induced by increasing the rotation rate while m...
Abyssal Channel Flow in Ocean General Circulation Models with Application to the Vema Channel
Abyssal Channel Flow Ocean General Circulation Models Vema Channel
2008/12/3
An idealized Cox model is shown to pass a flux given by g′H2/2f though a deep channel, single grid-box wide, consistent with analytical models. This flux can, however, be significantly increased or de...
Surface tension effect on a two dimensional channel flow against an inclined wall
free surface potential flow jet flow Weber number
2010/9/16
Surface tension effect on a two dimensional channel flow against an inclined wall is considered. The flow is assumed to be steady, irrotational, inviscid and incompressible. The effect of surface tens...
