Transient Heat Transfer of a Spiral Fin Year: 2016 Volume: 10 Issue: 7 1219 - 1223 Pages Authors: Sen-Yung Lee Li-Kuo Chou Chao-Kuang Chen Abstract: In this study, the problem of temperature transient response of a spiral fin, with its end insulated, is analyzed with base end subjected to a variation of fluid temperature. The hybrid method of Laplace transforms/Adomian decomposed method-Padé, is applied to the temperature transient response of the fin, the result of the temperature distribution and the heat flux at the base of the spiral fin are obtained, show a good agreement in the physical phenomenon. Keywords: Laplace transforms/Adomian decomposed method- Padé transient response heat transfer.
