2. 1. Performance of Compact Heat Exchanger in Non-Perpendicular Cooling Airflows

   Author : Lisa Henriksson; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulations; Angled; Experiments; Inclined; Heat transfer; Pressure drop; CFD; Heat exchanger;

   Abstract : During recent years the main focus in the vehicle industry has been on cutting the fuel consumption and emissions as well as improving the vehicle performance. To be able to meet these demands additional systems are being introduced into the vehicle. READ MORE

4. 2. Developments in Ground Heat Storage Modeling

   Author : Alberto Lazzarotto; Björk Folke; Michel Bernier; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Borehole fields; g-functions; network; inclined; integrated design; Energy Technology; Energiteknik; Byggvetenskap; Civil and Architectural Engineering;

   Abstract : Ground heat storage systems can play an important role for the reduction of green house gases emissions by increasing the exploitation of renewable energy sources and “waste heat” with a consequent diminution of the use of fossil fuels.A ground heat storage consists in an array of vertical boreholes placed in such a way that promotes the mutual thermal interaction between the ground heat exchangers creating the necessary conditions required to effectively store and retrieve heat.

5. 3. Analysis of underground concrete pipelines subjected to seismic high-frequency loads

   Author : Roghayeh Abbasiverki; Anders Ansell; Jan Laue; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Earthquake; High-frequency; Underground; Pipelines; Reinforced concrete; Inclined bedrock; Jordbävning; Högfrekvent; Underjordisk; Rörledningar pipelines ; Armerad betong; Lutande berggrund; Civil and Architectural Engineering; Byggvetenskap;

   Abstract : Buried pipelines are tubular structures that are used for transportation of important liquid materials and gas in order to provide safety for human life. During an earthquake, imposed loads from soil deformations on concrete pipelines may cause severe damages, possibly causing disturbance in vital systems, such as cooling of nuclear power facilities.

6. 4. Force and Flow Characteristics of a Partially Submerged Propeller

   Author : Niclas Olofsson; Chalmers University of Technology; []
   Keywords : partially submerged propellers; performance prediction theory; inclined propellers; dynamic blade loads; yawed propellers; blade vibration;

   Abstract : Model experiments have been conducted to determine the average and dynamic performance of a high-speed partially submerged propeller. The purpose of the experiments was to examine the influence of shaft yaw and inclination angles on the propeller characteristics at different Froude and cavitation numbers and to study the flow around the propeller blades in different conditions.
