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 ...

On Moderately Separated Viscous Flows
Journal of the Aerospace Sciences, 1961where r is the relaxation time and ae the equilibrium value at p and T. Eqs. (25) and (26) are similar to the corresponding equations of Sedney's, except for the different meaning of f\. All the terms on the right-hand side of Eqs. (25) and (26) are known from the given boundary conditions behind the shock, which may be evaluated from the frozen ...

Flow separation in supersonic convergent–divergent nozzles has been the subject of several experimental and numerical studies in the past. Today, with the renewed interest in supersonic flights and space vehicles, the subject has become increasingly important, especially for aerospace applications (rockets, missiles, supersonic aircrafts, etc.).

ADVANCES IN THE STUDY OF SEPARATED FLOWS
Acta Mechanica Sinica, 1988Summary: This paper consists of three parts. The first deals with the separation conditions for three-dimensional steady viscous separated flows, in which the behaviour of separated flow described by Navier-Stokes equations and boundary layer equations is studied.

The separating flow of an inviscid fluid is not only a limit solution of the steady separating, laminar fluid flow at high values of the Reynolds number but it is also part of its structure. This work aims at reexamining the separating flow of inviscid fluid past a bluff body which is fixed in an otherwise uniform stream of fluid.

Flow attachment at flow separation lines
1994Evolving flow structures leave definite but not unique “footprints” of the outer (off-wall, mid-air) flow on the wall. Bifurcating flows, characterized by dynamical systems for the velocity field reveal that two-dimensional separation bubbles together with their three-dimensional bifurcations are “embedded” between fully attaching and completely ...

Boundary-layer structure of prograde and retrograde rotating flows past a cylinder on a β-plane is investigated. It is found that β inhibits boundary-layer separation for prograde flows but it exerts no influence on the boundary-layer structure for retrograde flows. The results agree with the few available experimental observations.

Fluid Dynamics, 1982
Turbulent separation flows arise when objects move in the oceans and in the atmosphere, and also when a liquid or gas flows past elements of the Earth's relief, technological and industrial plant, and constructional elements. Therefore, problems of turbulent separation flows cover the entire range of velocities of continuum motions and under such ...

Cell Separations by Flow Cytometry
2003Flow cytometry is a means of measuring the physical and chemical characteristics of particles in a fluid stream as they pass one by one past a sensing point. The modern flow cytometer consists of a light source, collection optics and detectors, and a computer to translate signals into data.
