4. 2. Modeling and Performance Analysis of Alternative Heat Exchangers for Heavy Vehicles

   Author : Wamei Lin; Värmeöverföring; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Countercurrent flow; Graphite foam; Heat exchanger; Thermal performance; Computational fluid dynamics;

   Abstract : Cross flow heat exchangers made from aluminum are common as radiators in vehicles. However, due to the increasing power requirement and the limited available space in vehicles, it is extremely difficult to increase the size of heat exchangers (HEXs) placed in the front of vehicles.

5. 3. Experimental and Mathematical Study of Incompressible Fluid Flow through Ceramic Foam Filters

   Author : Shahin Akbarnejad; Ragnhild Elizabeth Aune; Pӓr Jönsson; Andreas Westermoen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Ceramic Foam Filters (CFFs) are widely used to filter solid particles and inclusions from molten metal in metal production, particularly in the aluminum industry. In general, the molten metal is poured on the top of a ceramic foam filter until it reaches a certain height, also known as metal head or gravity head. READ MORE

6. 4. Recyclable self-reinforced ductile fiber composite materials for structural applications

   Author : Christof Schneider; Dan Zenkert; Sohrab Kazemahvazi; Malin Åkermo; Ignace Verpoest; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-reinforced polymer; Composite; sandwich structure; mechanical properties; impact behaviour; finite element; Farkostteknik; Vehicle and Maritime Engineering;

   Abstract : Lightweight structures in vehicles are a proven way to reduce fuel consumption and the environmental impact during the use. Lower structural weight can be achieved by using high performance materials such as composites or using the material efficiently as a sandwich structure. READ MORE

7. 5. Li2O2 quantification in non-aqueous Li-O2 batteries with binder-free cathodes

   Author : Chenjuan Liu; Torbjörn Gustafsson; Martin Sahlberg; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The non-aqueous Li-air (Li-O2) battery has been emerging as one of the most promising high-energy storage systems to meet the requirements for electric vehicle applications due to its high theoretical energy density. In order to uncover the underlying electrochemistry and enable an informed battery design, it is crucial to gain a detailed understanding of the cell´s chemical components as well as its behavior during cycling.
