Eğimli Dikdörtgen Bir Kanalda Köpük Isı Alıcılardan Doğal Taşınımın Deneysel Olarak İncelenmesi

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 mad… Show more

“…The heat transfer results obtained for the empty surface and the foamed surface were compared and it is seen that with the use of aluminum foam heat sinks increases the heat transfer rate between approximately 36% and 70%. Doğan and Ozbalcı [10] have experimentally investigated the natural convection heat transfer from porous materials mounted in an inclined rectangular duct. The experiments were made for different Rayleigh Number range from 2.03 x10 7 to 1.33 x10 8 and the channel inclination angles were varied from 0° to 90°.…”
