Just as optical flow is the two-dimensional motion of points in an image, scene flow is the three-dimensional motion of points in the world. The fundamental difficulty with optical flow is that only the normal flow can be computed directly from the image measurements, without some form of smoothing or regularization.

Three-Dimensional Flow in the Upper Ocean
Science, 1985Measurements 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, 1971A 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, 1991Summary: 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 flow separation
Sadhana, 1993Separation 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 Laminar Flow in Ducts
Numerical Heat Transfer, Part B: Fundamentals, 1981A 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 Characterization of Internet Flows
2011 IEEE International Conference on Communications (ICC), 2011In 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, 1979The 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.
