“…The trends also show a decrease of the relative influence of radiation to the experimental values when the temperature difference increases. The same trends were observed by Sparrow and Vemuri [19]. The results of our study clearly show that for buoyancy driven convection in open-cell metal foam the radiative share in the total heat transfer cannot be neglected.…”

“…The influence of radiation is the highest for the largest foam height, up to 30% of the total heat transfer rate. This is well within the expected range of 25e40% [19]. The trends also show a decrease of the relative influence of radiation to the experimental values when the temperature difference increases.…”

“…Foams can be categorized as dense sinks as the cells are smaller than 6 mm diameter. Sparrow and Vemuri [19] studied the effect of orientation and radiation on natural convection/radiation heat transfer in pin fins. The fractional contributions of radiation to the combinedmode heat transfer were generally in the 25e40% range, with the larger contributions occurring for the smaller temperature differences between substrate and environment.…”

“…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 contribution of radiation was determined to be substantial and was greatest for more populous arrays, for longer fins, and at small baseplate-to-ambient temperature differences. Sparrow and Vemuri [13] later extended their study to different orientations. Aihara et al [14] carried out an experimental study on natural convection and radiation heat transfer from dense pin fin arrays with a vertical base plate.…”
