2. 1. Engine Thermal Management in Heavy Duty Vehicles

   Author : Arne Andersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Control Simulation; Heat Exchangers; Heat Transfer; Thermal Management; Turbomachinery;

   Abstract : Future regulations on noise and exhaust emissions have a large impact on heavy duty engine installations. Cooled EGR is used for NOx abatement. Better sealed engine encapsulations are used to meet new noise regulations. Engine thermal management is therefore becoming an increasingly important discipline. READ MORE

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.
