Abstract
An experimental investigation was conducted to evaluate and compare the thermal-hydraulic performances of crossflow microchannel condensers using louvered fins and metal foams as extended surfaces. Three copper foam surfaces with pore densities of 10 and 20 PPI and porosities of 89.3% and 94.7% were compared with three aluminum louvered fins with lengths of 27 and 32 mm (in the flow direction) ...
In many applications, such as the miniaturization and cooling of high-power electronics in aerospace, a new thermal management solution is needed, metal foam radiators may be valuable solution. this work, X-ray scanning was applied to obtain original structure foam. The real calculation model obtained through series modeling, high-precision numerical simulation built study heat mass transfer ho...
The aim of this study was to investigate the potential application metal foams in shell-tube recuperators. A356 aluminium foam cast around internal and external surfaces a thin-walled copper tube enhance heat transfer between separated water streams at different temperatures. results demonstrated that drastically increased efficiency due its large volumetric surface area high thermal conductivi...
With the massive consumption of fossil fuels and its detrimental impact on the environment, methods of generating clean power are urgent. Hydrogen is an ideal carrier for renewable energy; however, hydrogen generation is inefficient because of the lack of robust catalysts that are substantially cheaper than platinum. Therefore, robust and durable earth-abundant and cost-effective catalysts are ...
L. Dahil, Istanbul Aydın University, Department of Mechanical and Metal Technologies, Turkey. A. Karabulut, Afyon Kocatepe University, Faculty of Technology, Mechanical Engineering, Turkey. In this study, it was aim ed to decrease the vibration reaching to passenger from the legs of vehicle seats. In order to determine the levels of vibrations reaching at passengers, a test pad placed under the...
