A Study of Annular Slurry Jet for Abrasive Waterjet Cutting

The present article deals with the analysis of thermal-bending stresses in a heated thin annular sector plate with simply supported boundary condition under transient temperature distribution using Berger’s approximate methods. The sectional heat supply is on the top face of the plate whereas the bottom face is kept at zero temperature. In this study, the solution of heat conduction is obtained...

abstract annular pancreas (ap) is a rare congenital malformation resulting from failure of pancreas ventral anlage rotation with the duodenum. this leads to a ring of pancreatic tissue that envelops the duodenum. clinical manifestations of ap most commonly develop in infancy or early childhood but can present at any age. the diagnosis of ap, usually suggested by an upper gi series or abdominal ...

Perturbations in the southern annular mode (SAM) are shown to be significantly correlated with SST anomalies in the central tropical Pacific during austral winter and SST anomalies in the eastern tropical Pacific during austral summer. The SAM signature in the Pacific sector resembles a tropically forced Rossby wave train, the so-called Pacific–South American pattern, while the signature in the...

Recent advances in computer science and highly parallel algorithms make Large Eddy Simulation (LES) an efficient tool for the study of complex flows. The available resources allow today to tackle full complex geometries that can not be installed in laboratory facilities. The present paper demonstrates that the state of the art in LES and computer science allows simulations of combustion chamber...

The usefulness of theoretical research results in design depends to a large extent upon their generality and simplicity. For this reason, closed-form solutions are presented in this paper for a number of plate bending problems, these being: (1) a sector cut from an annular plate, loaded along its straight edges; and (2) a semi-infinite plate or a circular plate subjected to concentrated moments...

This paper present a new kind of equipment called the annular reactor, which has been designed to treat a great number of substrates with a particularly good uniformity of thickness of deposits on the batch. Furthermore, a small scale pilot plant of this apparatus, called the sector reactor, has been built. It constitutes a very convenient laboratory piece of equipment, particularly useful to p...
