Taschenbuch. Zustand: Neu. Neuware -Fins are the extended surfaces through which heat transfer takes place to keep the base surface cool. Fins of various configurations are presently used ranging from automobile, aero engines to cooling of chip in a computer. Note that in a fin majority of the heat transfer to atmosphere is by convection and therefore in the present research importance is given to variation of temperature along the length of the fin which in turn gives rate of heat transfer. In the present research experiments a solid rectangular aluminium fin and the same rectangular fin with different embossing¿s and perforations were compared analytically, experimentally and its validity through finite element analysis (FEA) for its temperature distribution along the length. From the present research experiments it is observed that the mathematical, experimental and FEA for a solid rectangular fin without perforations are converging within +/- 1 oC and rectangular fin with embossing¿s perforations are converging within +/- 2 oC and hence the validity.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 60 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -This review presents the results obtained and the deductions made from a series of microstructural studies to determine Eutectic Cell Count (ECC), Dendrite Arm Spacing (DAS), and Grain Size (GS) of hypoeutectic gray cast iron which was sand cast using metallic, non metallic, water cooled and sub- zero (Cryogenic) end chills. Analysis of the data on chilled cast iron show that the cooling rate has a marked effect on eutectic cell size, dendrite spacing and grain size. It is observed that, the number of eutectic cells as an index of graphite nucleation and the effect of these on structure and properties, since the eutectic cells are developed on the graphite nuclei during solidification. The review suggest that some of the graphite in the structure of cast iron form more readily as a result of the decomposition of carbides during and after solidification process rather than being an outcome of the direct growth of the graphite form the liquid. It was found that microstructure, DAS, ECC and GS are highly dependent on the location of the casting from where the test samples were taken (chill end) and also on the chilling rate.Books on Demand GmbH, Überseering 33, 22297 Hamburg 64 pp. Englisch.
