Abstract Structural elements in the form of annular sectorial plates are widely used aeronautical, biomedical, and marine engineering. When these components exposed to dynamic load, large-amplitude vibrations occur. The vibration response analysis based on linear strain-displacement relation typically yields a conservative estimate can be as first approximation actual solution for thin structur...

In this article, the axisymmetric stability of an elastic annular plate with distributed internal heat source under uniform constant compressive radial loading at outer edge is investigated. The governing and compatibility equations are taken from modified Karman’s equations, which solved by shooting method. effect density on critical load investigated discussed in detail. Numerical results wit...

The novel electrostatic micropump model for applications such as in biomedical drug delivery is presented. geometrical arrangement of the coupling rigid electrodes lets us exploit our mathematically rigorous boundary integral equation formulation and its solution. Thus, charge densities involving fringe effects on plates are obtained by means analytical regularization method (ARM) constructed a...

We describe a theoretical and experimental study of an axisymmetric viscous gravity current with constant flux, confined to the space between two horizontal parallel plates. The effect confinement results in regions flow: inner region where fluid is contact both plates outer annular forms along lower plate. present simple model that describes flow dynamics by single dimensionless parameter $J$ ...

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...

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 ...
