The functionally graded materials (FGM) have many advantages especially in thermal environments, and in the recent years they have been used in many engineering applications. A FGM plate is an inhomogeneous composite made of two constituents (usually ceramic and metal), with both the composition and the material properties varying smoothly through the thickness of the plate. The FGM plate vibra...

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...

In this study, the symplectic method is applied to a two-dimensional annular-sector viscoelastic domain under the polar coordinate system. By applying variable separation approach, all fundamental solutions are derived in analytical form. Furthermore, using the method of variable substitution, lateral conditions are transformed into finding a particular solution for the governing equations, and...

annular pancreas is a rare congenital condition of the pancreas where the pancreatic tissue either partially or completely covers the duodenum by forming a ring. endoscopic ultrasound is rarely considered as the first diagnosis tool for annular pancreas. we here present a 48 years old man who was primarily provisionally diagnosed with pancreatic mass and was planned for pancreatoduodenectomy. b...

Abstract In this paper, free vibration and transmission response for the torsional of circular annular plate are presented. To author’s knowledge, few studies can be found from wave standpoint. For purpose, in study, natural frequencies with clamped–clamped free–free boundaries calculated. The obtained by approach compared those derived classical method. Furthermore, transmissibility curves per...

The annular foam breaker is one which uses the vacuum and shear force generated by the Coanda effect to break foam. The pressure distribution directly affects its performance. So an investigation on the flow characteristics inside the annular foam breaker is important to optimize its structure. In this paper, the computational fluid dynamics (CFD) code, FLUENT, is employed to simulate the flow ...
