Transition in Localized Pipe Flow Turbulence
Physical Review Letters, 2009Direct numerical simulation of transitional pipe flow is carried out in a long computational domain in order to characterize the dynamics within the saddle region of phase space that separates laminar flow from turbulent intermittency. For Reynolds numbers ranging from Re=1800 to 2800, a shoot and bisection method is used to compute critical ...

Genomics of local adaptation with gene flow
Molecular Ecology, 2016AbstractGene flow is a fundamental evolutionary force in adaptation that is especially important to understand as humans are rapidly changing both the natural environment and natural levels of gene flow. Theory proposes a multifaceted role for gene flow in adaptation, but it focuses mainly on the disruptive effect that gene flow has on adaptation when ...

Quantifying local flow direction uncertainty
International Journal of Geographical Information Science, 2013Absolute elevation error in digital elevation models (DEMs) can be within acceptable National Map Accuracy standards, but still have dramatic impacts on field-level estimates of surface water flow direction, particularly in level regions. We introduce and evaluate a new method for quantifying uncertainty in flow direction rasters derived from DEMs. The

Local regulation of oviductal blood flow
General Pharmacology: The Vascular System, 19961. Blood flow to the oviduct is implicated in the genesis and maintenance of oviductal fluid, in this way contributing to the creation of an adequate medium for ovum/embryo physiology. Therefore, factors controlling the tone of the vessels supplying the oviduct would be expected to affect its luminal environment.

Flow simulation with locally-refined LBM
Proceedings of the 2007 symposium on Interactive 3D graphics and games, 2007We simulate 3D fluid flow by a locally-refined lattice Boltzmann method (LBM) on graphics hardware. A low resolution LBM simulation running on a coarse grid models global flow behavior of the entire domain with low consumption of computational resources.

Local Blood Flow and Local Metabolism in the Brain
1987Local blood flow and local metabolism can be quantified in the brain using methods which are based on the same principles in experimental animals and in man. Local blood flow can be measured using either inert gases or nonvolatile tracers. In experimental animals, autoradiographic methods have been established, since they present several advantages, e ...

Localized spirals in Taylor-Couette flow
Physical Review E, 2008We present a type of spiral vortex state that appears from a supercritical Hopf bifurcation below the linear instability of circular Couette flow in a Taylor-Couette system with rigid end plates. These spirals have been found experimentally as well as numerically as "pure" states but also coexist with "classical" spirals (or axially standing waves for ...

The Growth of Localized Disturbances in Unstable Flows
Journal of Applied Mechanics, 1982The development of three-dimensional localized disturbances in unstable flows was recently studied by Craik [1] using a model dispersion relation. The adoption of such an approximate formula for the linear dispersion relation allows a dramatic reduction in computational effort, in comparison with more precise calculations (e.g., Gaster [3], [5]), yet ...
