WebExtended surfaces, or fins, are a popular topic of heat transfer [1], [2] and [3]. Fin is a surface which extends from the heat exchange object to increase the rate of heat transfer to or from the environment. Generally this thesis is dedicated to different heat transfer problems in cylindrical systems with extended surfaces – fins.

Thermal conductivity, heat transfer coefficient, and the source or sink term are assumed to be temperature dependent. In the model considered, the source or sink term is given as an arbitrary function. We employ symmetry techniques to determine forms of the source or sink term for which the … in a inane way
Heat Transfer and Temperature Distribution in a Fin
WebNov 30, 2024 · In this study, different step ratios were set for comparative research. When using down stepped fins with a step ratio of 0.4, compared with traditional equal volume horizontal fins, the melting rate of PCM increased by 56.3 % at 800 s and 65.5 % at 3600 s. The detailed structure of the fin is shown in Fig. 2 (g). WebSteady state heat transfer through pipes is in the normal direction to the wall surface (no significant heat transfer occurs in other directions).
