Three-Dimensional Flow in the Upper Ocean

Science, 1985
Measurements made from the Research Platform FLIP provide some of the first direct observations of three-dimensional flow within the surface mixed layer of the ocean. Relatively narrow regions of downwelling flow were found within the mixed layer, in coincidence with bands of convergent surface flow. At mid-depth in

Three-dimensional uniform flow in an oxygenator

Medical & Biological Engineering, 1971
A fully established three-dimensional blood flow in a uniform, rectangular channel with a moving wall (membrane) is calculated by using an implicit finite-difference approximation to the Navier-Stokes equations. The strength of the secondary flow, which provides a mechanism for the enhancement of oxygen transfer, is controlled by the relative motion ...

THREE-DIMENSIONAL FLOW IN A POROUS CHANNEL

The Quarterly Journal of Mechanics and Applied Mathematics, 1991
Summary: This paper describes three-dimensional flow of a viscous incompressible fluid driven along a channel by uniform suction through parallel porous walls, generalizing recent work on two-dimensional flow. The Navier- Stokes equations are reduced to two nonlinear diffusion equations with time and the coordinate normal to the walls as independent ...

Three-Dimensional Laminar Flow in Ducts

Numerical Heat Transfer, Part B: Fundamentals, 1981
A finite-element marching procedure is presented for the calculation of transport processes in three-dimensional parabolic flows As in corresponding finite-difference procedures, equations are solved one after the other. Similarly, longitudinal and cross-stream pressure gradients are uncoupled.

Three-dimensional flow separation

Sadhana, 1993
Separation of three-dimensional flow, although much more common than its two-dimensional counterpart, has defied precise description and definition in spite of numerous attempts. Here, we briefly review the grammar that is used to describe various facets of the phenomenon, and use some recent numerical and experimental results to illustrate the ...

Three-Dimensional Characterization of Internet Flows

2011 IEEE International Conference on Communications (ICC), 2011
In this paper a three-dimensional (size, duration and rate) flow traffic characterization framework is proposed. Detailed investigation of application clusters in the characterization space is discussed. The use of the framework is demonstrated on measured traffic from a commercial network.

On Stability and Transition in Three-Dimensional Flows

AIAA Journal, 1979
The usefulness of the e" method for predicting transition in two-dimensional and axially symmetric flows is well established. In order to extend the method to three-dimensi onal parallel shear flows, it is first necessary to establish a relationship between a and /?, the complex wave numbers in two perpendicular directions in the plane of flow.

A three-dimensional cerebrovascular flow phantom

Medical Physics, 1999
We have constructed a life-sized fully three-dimensional (3D) rigid flow-through model of the cerebral vasculature. Average vessel diameters and lengths, taken from published values in the literature, were used to describe the geometry of our phantom; numerically controlled machining techniques were used to fabricate the model. Inflow to the phantom is

One-Dimensional and Three-Dimensional Models of Cerebrovascular Flow

Journal of Biomechanical Engineering, 2004
The Circle of Willis is a ring-like structure of blood vessels found beneath the hypothalamus at the base of the brain. Its main function is to distribute oxygen-rich arterial blood to the cerebral mass. One-dimensional (1D) and three-dimensional (3D) computational fluid dynamics (CFD) models of the Circle of Willis have been created to provide a ...
