... are the main targets of this paper. Findings The introduced temperature slip at the base penetrates through the surface of the fin and reorganizes the distribution of temperature all over the surface. The overall impact of the temperature jump on the fin efficiency is such that it acts to lower the fin...

... of the spine and thermal fin efficiency are also given. Originality/value Without the traditional arc length assumption, the pin fin is shown to be an effective extended surface to remove the excessive heat from the hot surface it is pinned to. Optimum pin fin dimensions leading to the maximum base heat...

... the classical Adomian decomposition method, it is easy to gain the range of parameters guaranteeing the convergence of the Adomian series. Findings With the presented improvement, the reliable behavior of the fin tip temperature and the fin efficiency of the most interested from practical perspective...
