In thermal science courses, flow over curved objects, like cylinders or spheres are generally discussed qualitatively, followed by the presentation of numerical or experimental results for the drag coefficient, Nusselt number, and flow separation. Rarely, there is much discussion of how solutions are obtained. In this paper the flow separation is first

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.).

Heat Transfer in Separated Flows
Journal of the Aerospace Sciences, 1959Results of an experimental heat-transfer investigation in regions of separated flow are presented and compared with the theoretical analysis of NACA T N 3792. The average heat transfer for both laminar and turbulent separated boundary layers was found to be from 35 to 50 per cent less than that for equivalent attached boundary layers. The overall scope

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.

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.

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.

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.

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 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 ...
