1. 16. A study of heat transfer from cylinders in turbulent flows by using thermochromic liquid crystals

   Författare :Roland Wiberg; KTH; []
   Nyckelord :Fluid mechanics; convection heat transfer;

   Sammanfattning : In gas quenching, metal parts are rapidly cooled from hightemperatures, and the convection heat transfer coefficientdistributions are of importance for the hardness and thedistortion (the shape nonuniformities) of the quenched parts.Thermochromic liquid crystals (TLC) and a thin foil techniques,were investi- gated and used for studies of a circular cylinderin axial flows, affected and not affected by upstream owmodifying inserts.

3. 17. Time-accurate Turbulence Modeling of Swirling Flow for Hydropower Application

   Författare :Ardalan Javadi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hybrid RANS-LES; Swirling Flow; DES; Vortex Breakdown; Turbulence Modeling; Hydropower; LES;

   Sammanfattning : Hydraulic turbomachines have played a prominent role in the procurement of renewableenergy for more than a century. Embedded in the context of general technological progress,their design for efficiency and reliability has reached an outstanding level of quality. LÄS MER

4. 18. Predictions of Aerodynamically Induced Wind Noise Around Ground Vehicles

   Författare :Jonas Ask; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; side mirror; LES; incompressibility; Curle; CAA; air rush noise; low Mach number; ground vehicle; cavity;

   Sammanfattning : Over the last decade wind noise has with few exceptions consistently generated a constant or even growing level of customer complaints to automotive companies world-wide. This can partly be explained by a relatively greater focus on engine, power-train and tire noise combined with a growing need to reduce weight in future cars. LÄS MER

5. 19. Slack-Time Aware Dynamic Routing Schemes for on-chip networks

   Författare :Daniel Andreasson; Jönköping University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Network on Chip; Dynamic Routing; Router design; Routing algorithms; Slack-time; Electronics; Elektronik; Computer science;

   Sammanfattning : Network-on-Chip (NoC) is a new on-chip communication paradigm for future IP-core based System-on-Chip (SoC), designed to remove a number of limitations of today’s on-chip interconnect solutions. A NoC interconnects cores by means of a packet switched micro-network, which improves scalability and reusability, resulting in a shorter time to market. LÄS MER

   Sammanfattning : Abstract: During the past decade, media researchers have intensified the study of media scandals and the role of journalism as an institution that holds social actors responsible for malfeasance and wrongdoings. On a micro level of analysis, the main attention has beendirected towards the journalistic interview and its use to promote the impression of guilt and journalistic neutrality. LÄS MER
