Flow Separation and Separated Flows
2015As stated at the end of Chap. 5, if at large Reynolds numbers a moving body is dressed in fully attached boundary layers, the flow can be solved by potential-flow theory with good accuracy, and then a boundary-layer correction yields the friction force to the body.

Twelfth IEEE International Workshop on Quality of Service, 2004. IWQOS 2004., 2004
This paper elaborates on a paradigm for quality-of-service (QoS) that is local, i.e., it does not depend on multinode cooperation. In order to maintain short queuing delays, we individuate flows that occupy a large fraction of a buffer and segregate those flows into a separate queue.

During the sea-level ignition process of rocket motors, the nozzle is subjected to an overexpanded e ow condition that can cause high side loads. Prediction of the symmetrical separation location is the e rst key step to a determination of the range of possible side-load magnitudes.

Adaptive control of separated flows
2003 European Control Conference (ECC), 2003Two adaptive feedback control methods, a new adaptive integral controller used to control plants with output saturation and dead-time and the well-known extremum seeking feedback are employed to control detached flows. For the experimental validation, conducted in a wind tunnel, two different flow configurations, a backward-facing step and a diffuser ...

Abstract Flow separation is perhaps the most important unsolved phenomenon of fluid mechanics which causes energy loss and deviation of stream lines. A summary of flow separation is presented in order to understand the basic problem, the present state of knowledge and to indicate future development.

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 ...

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

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

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.
