Experimental Investigation of Free Convection from Foam Heat Sinks in an Inclined Rectangular Channel
Journal Title: Cumhuriyet Science journal - Year 2018, Vol 39, Issue 3
Abstract
In this present study, free convection from an in-line 5x1 array of aluminum foam heat sinks which were placed on the bottom wall of the inclined rectangular channel was investigated. Aluminum foam heat sinks were made of Al-6101 alloy. All heat sinks mounted on a bottom wall of the channel was discrete form and exposed to uniform heat flux. Aluminum foam materials with three different pore densities (10, 20 and 40 PPI) were used in experiments. Air was used as coolant fluid (Pr =0.7). The experiments were made for Rayleigh Number range from 2.03 x107 to 1.33 x108 and the channel inclination angles were varied from 0° to 90°. Moreover, the heat transfer results from the aluminum foam heat sinks were also compared to the results obtained for foam-free (without foam) surfaces. The results showed that both the channel inclination angle and the usage of foam heat sinks are significant influences on heat transfer results.
