Bridging the gap between annular and can-annular acoustic spectra

The Journal of the Acoustical Society of America
In the literature on thermoacoustic instabilities in combustors, a distinction is typically made between annular and can-annular systems because these are the most common gas turbine architectures. In reality, however, annular combustors typically feature discretely symmetric elements, such as burner tubes, and can-annular combustors feature an ...

Development of annular gap junctions in guinea pig epithelia

Journal of Oral Pathology & Medicine, 1979
Abstract. Epithelia from skin, palate, buccal mucosa and dorsal tongue were studied in normal and zinc deficient guinea pigs by transmission electron microscopy. Gap junctions (nexuses) were observed primarily in the basal and prickle cell layers.

The origin of annular junctions: a mechanism of gap junction internalization

Journal of Cell Science, 2001
ABSTRACT Gap junctional intercellular communication is established when connexin proteins oligomerize into connexon hemichannels, which then pair at the cell surface with connexons from neighboring cells to form functional gap junction channels.

Degradation of Annular Gap Junctions of the Equine Hoof Wall

Cells Tissues Organs, 1984
Annular gap junctions interiorized within cells of the stratum spinosum of the coronary border of the equine hoof were degraded by two methods. Some were autophagocytized and some appeared to fuse with lysosomes to form heterophagosomes. Structural changes of partially degraded annular gap junctions included increased density of the enclosed cytoplasm,

Mass transfer in a rotating annular gap

Theoretical Foundations of Chemical Engineering, 2006
The mass transfer in a rotating annular gap is theoretically calculated. The calculation results are compared with experimental data on the desorption of carbon dioxide from an aqueous solution into air.

Particle flux in an annular gap about a sphere

Annals of Nuclear Energy, 2005
Abstract We develop a method for joining diffusion theory to a void region in a consistent manner. In particular, we apply the theory to a three region problem with a central solid core, surrounded by a concentric void shell and this in turn is surrounded by a concentric shell of another solid material. The sources can be either incident on the outer

Magnetosphere Structure and the Annular Gap Model of Pulsars

2009
Pulsar radio and γ-ray emission has been studied for about forty years, yet no elaborated model is present to account for all the emission of pulsars from radio to γ-ray bands. A reasonable emission model should present the mechanism for wide band radiation. The magnetosphere structure and particle acceleration regions are the basis for solving problem,

Convective boiling heat transfer in a concentric annular gap

International Journal of Multiphase Flow, 1983
Abstract Heat transfer and pressure drop characteristics were measured in both subcooled and saturated concentric narrow gap forced convection boiling. Four boiling regimes were observed: isolated bubbles, coalesced bubbles, coalesced bubbles with small dry patches, and liquid deficient flow.

Flow of ferrofluid in an annular gap in a rotating magnetic field

Physics of Fluids, 2010
An asymptotic solution is obtained for flow of a ferrofluid between two stationary coaxial cylinders of infinite extent, including the effects of spin viscosity. This solution takes into account the nonuniformity of the magnetic field in the annular space that arises as a consequence of the demagnetizing field of the inner cylinder.
