Annular beam X-ray imaging
… imaging by scanning objects through an annular beam of X‐rays. The resultant ring shaped projections record depth dependent parallax. The study focuses on two different scanning methods. First, a single axis scan has been employed to record curvilinear stereoscopic images. Second, a two …

Aerodynamic design of annular ducts
… and numerical methods for designing axisymmetric annular ducts having geometries capable of supporting fluid flows with prescribed performance characteristics. Three basic numerical methods of solution are given and are used to obtain results to the known exact solutions for a class of …

Transient Phenomena in Annular Combustors
… transient phenomena related to the operation of annular gas turbine combustors, namely ignition and blow-off. The experiments were conducted on complex multi-burner geometries, close to realistic combustors, to provide a wide data set including stability limits, flame regimes and physical …

Annular Beam Shaping And Optical Trepanning
… is a new laser drilling method using an annular beam. The annular beams allow numerous irradiance profiles to supply laser energy to the workpiece and thus provide more flexibility in affecting the hole quality than a traditional circular laser beam. Heating depth is important for …

Unsymmetrical large deflections of an annular plate
… of thin plates have been presented for annular plates under certain axisymmetric/loading conditions, little work has been done with unsymmetrical large deflections. In this investigation a systematic mathematical iteration technique is used to obtain a solution to the von Karman …

Dynamics of biofilm processes in an annular reactor
… associated with fouling biofilm development. An Annular Fouling Reactor was used as the experimental system. Nutrients, glucose and in some cases a synthetic growth media, were added to the reactor to provide the necessary mineral, energy and carbon requirements for microbial growth. Material …

Flows through s-shaped annular, inter-turbine diffusers
… performance of two different severity diffusing annular sshaped ducts, with the same overall diffusion ratio of 1.5, in order to validate the CFD code M.E.F.P. The first less severe diffusing duct was used to investigate the effects of inlet swirl on the duct performance. It was found that at an …

Annular modes in multiple migrating zonal jet regime
… have linked hemispheric climate variability to annular modes, zonally symmetric structures that describe the horizontal redistribution of atmospheric mass. The resulting changes in the pressure patterns consequently alter the atmospheric circulation, including the movement of zonal jets in the …

Odd annular Bar-Natan Category and Gl(1|1)
… by Brun-dan and Ellis in [5], and the odd annular Bar-Natan category BNo(A), which generalizes the odd Bar-Natan category studied by Putyra in [16]. We then show there is an equivalence of categories between them if δ=0. We use this equivalence to better understand the action of the Lie …

Annular Flow in a Low - Pressure Steam - Water System
<p>Two-phase annular flow is an important aspect of two- phase flow. Three different models, Ghosal, Wallis, and Levy models, were used to calculate the pressure drop in an nular two-phase flow. The calculated pressure drop was com pared with a set of experimental data. The pressure range of the …

Steklov Eigenvalue Problems on Nearly Spherical and Annular Domains
… eigenvalues on nearly spherical and nearly annular domains in d dimensions where d is any given positive integer. By using the Green-Beltrami identity for spherical harmonic functions, the derivatives of Steklov eigenvalues with respect to the domain perturbation parameter can be determined …

Continous annular chromatography for the separation of carbohydrate mixtures
… waste product was carried out using a rotating annular chromatograph. The annulus was 12 mm wide and 1.4 m long and was packed with a sodium charged 5.5% cross-linked polystyrene ion exchange resin. Separation was achieved by the simultaneous mechanisms of ion exclusion, size exclusion and …
