There exist two very simple classical models for separated flow behind a bluff body - Helmholtz/Kirchhoff and Prandtl/Batchelor. These both have a pleasant simplicity but agreement with experiment is only qualitative. A simple combination of these two is presented for flow down a step which gives better quantitative results.

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 ...

Continuous‐flow Blood Cell Separation
Transfusion, 1968The continuous‐flow blood cell separator is capable of continuously removing blood from a donor, separating this blood into its various components, retaining certain components, and returning the balance to the donor. The first part of this paper is concerned with studies made to determine the centrifuge bowl configuration.

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

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 ...

Separation is an important characteristic of the type of flow encountered in many modern heat transfer devices. Design requirements of compactness have resulted in the rapid growth of the use of complex geometrical heat transfer surfaces, which have developed from the single tube and tube bank placed across the line of flow.

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.

Cryptosteady-Flow Energy Separation
Journal of Fluids Engineering, 1973The mechanism of cryptosteady-flow energy separation is described and analyzed in its most general form, with full consideration of the effects of bearing friction or other rotor torque, and of such asymmetries as unequal discharge pressures, peripheral velocities, flow losses, prerotation velocities, and discharge angles.
