2. 16. A multi-scale approach for predicting the fire response of building barriers

   Author : Blanca Andrés Valiente; Avdelningen för Brandteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fire; Building Barriers; Heat transfer; Experimental; Gypsum; Stone wool; furnace; H-TRIS;

   Abstract : Building barriers are compartmentation elements in buildings that limit the passage of fire and smoke to adjacent spaces. They are key elements in the overall response of a building in a fire. The adequate fire response of building barriers is usually assessed by the fulfilment of standardized resistance to fire tests.

4. 17. CFD Modeling of Combustion in Flexi-Fuel Burners at Gas Turbine Conditions

   Author : Abdallah Abou-Taouk; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAS-SST; Global reaction mechanism; CFD; LES; RANS; Combustion; PSR; Chemistry;

   Abstract : The main source of energy in the nearest future will come from fossil fuels. Increasing demands on environmentally friendly energy conversion implies that pollutants, such as CO and NOx, need to be reduced. READ MORE

5. 18. SOFC Modeling from Micro- to Macroscale: Transport Processes and Chemical Reactions

   Author : Hedvig Paradis; Värmeöverföring; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mass transport; diffusion; microscale; porous media; kinetics; LBM; CFD; anode multicomponent; MATLAB;

   Abstract : The purpose of this work is to investigate the interaction between transport processes and chemical reactions, with special emphasis on modeling mass transport by the Lattice Boltzmann method (LBM) at microscale of the anode of a solid oxide fuel cell (SOFC). In order to improve the performance of an SOFC, it is important to determine the microstructural effect embedded within the physical and chemical processes, which usually are modeled macroscopically.

6. 19. Active Junction Control and Piezoelectric Hybrid Damping for Improving the Acoustic Performance of Lightweight Structures

   Author : Jonas Svensson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hybrid passive-active control; Piezoelectric shunt damping; Sound radiation; Active junction control;

   Abstract : Weight reduction is a key factor in lowering the fuel consumption and thereby the greenhouse emissions from vehicles. However, reducing the weight normally results in a deterioration of the acoustic performance. Thus, the purpose of this thesis is to investigate damping treatments for lightweight vehicle panels.

7. 20. Experimental and Numerical Investigations of Confluent Round Jets

   Author : Klas Svensson; Bahram Moshfegh; Patrik Rohdin; Bengt Sundén; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Confluent jets; Multiple jet array; Jet interactions; Confluent Core Zone CCZ ; Particle Image Velocimetry PIV ; Laser Doppler Velocimetry LDA ; Computational Fluid Dynamics CFD ; Response Surface Methodology;

   Abstract : Unconfined multiple interacting confluent round jets are interesting from a purely scientific point of view, as interaction between neighboring jets brings additional complexity to the flow field. Unconfined confluent round jets also exist in various engineering applications, such as ventilation supply devices, sewage disposal systems, combustion burners, chemical mixing or chimney stacks.
