“…This has been shown by Edwards and Chaddock [24] [27,28], The common conclusion of the aforementioned studies was that the radiation heat transfer contributes between 25-40% to the total heat transfer from fin arrays in naturally cooled heatsinks. The goal of this study is to investigate the effects of fin interruption in natural convection.…”

This paper presents a review of investigation of thermal performance in natural convection from different geometrical fins. There are many methods for investigation of thermal performance of fins with different geometrical parameters. The thermal performance in natural convection from different geometrical fins being reviewed includes analysing the natural convective heat transfer from vertical fins, also similarity solutions for boundary layer equations for the cases of uniform surface heat flux, analytical work on vertical channels, an analytical study to investigate the natural convective heat transfer from two parallel plates, correlated the Nusselt number based on the squared root of the wetted area for the three dimensional bodies, a numerical approach to investigate the developing flow in the channel and the heat transfer between symmetrically heated, isothermal plates, the heat transfer from inclined interrupted fin channels, calculated natural heat transfer coefficients for four different fin arrays and three different base plates, the natural convection and radiation heat transfer From twelve large vertically based fin arrays also naturally cooled vertical shrouded fins. This present paper can be used as the first guideline for the researcher for changing different orientation of the interrupted fins for 3-D analysis by using FLUENT software also numerical model for investigation of interruption effects

“…The silicon walls act as two non-uniform cross section fins that are exposed to the ambient with variable convective heat transfer coefficient and also variable temperature. The one dimensional finite volume method is applied to solve this kind of conjugated heat transfer problem [24,25]. Subcooled water mass flow rate and its temperature are considered as inlet boundary conditions.…”

“…Effect of the variations of convective heat transfer coefficient on the optimum profile of a pin fin was studied by Kobus and Cavanaugh [5]. Azarkish et al [6] optimized the geometry of a longitudinal fin with volumetric heat generation under the influences of natural convection and radiation. Most of the above-mentioned studies optimized the geometries of an isolated fin.…”
