wikify date March 2011 In thermal engineering , an annular fin is a specific type of fin used in heat transfer that varies, radially, in cross sectional area. Adding an annulus mathematics annular fin to an object increases the amount of surface area in contact with the surrounding fluid , which increases the convection convective heat transfer between the object and surrounding fluid. Because surface area increases as length from the object increases, an annular fin transfers more heat than a similar pin fin at any given length. Annular fins are often used to increase the heat exchange in liquid gas heat exchanger systems. Governing equation File Annular Fin.jpg thumb right To derive the governing equation of an annular fin, certain assumptions must be made. The fin must have constant thermal conductivity and other material properties, there must be no internal heat generation, there must be only one dimensional heat conduction conduction , and the fin must be at steady state .

It can result from growth of a bifid ventral pancreatic bud around the duodenum, where the parts of the bifid ventral bud fuse with the dorsal bud, forming a pancreatic ring. It can also result if the ventral pancreatic bud fails to fully rotate, so it remains on the right or if the dorsal bud rotates in the wrong direction, such that the duodenum is surrounded by pancreatic tissue.

These images are formed by collecting scattered electrons with an annular dark field detector. In traditional dark field imaging, an objective aperture is placed in the diffraction plane so as to only collect electrons scattering through that aperture, avoiding the main beam. An annular dark field detector collects electrons from an annulus around the beam, sampling far more scattered electrons than can pass through an objective aperture. This gives an advantage in terms of signal collection efficiency and allows the main beam to pass to an Electron energy loss spectroscopy EELS detector, allowing both types of measurement to be performed simultaneously. An annular dark field image formed only by very high angle, incoherently scattered electrons as opposed to Bragg scattered electrons is highly sensitive to variations in the atomic number of atoms in the sample Z contrast images .
