2. 1. Experimental analysis of thermal mixing at reactor conditions

   Author : Mattia Bergagio; Henryk Anglart; Paolo Vinai; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mixing estimator; empirical mode decomposition; Hilbert-Huang transform; uncertainty assessment; radial heat flux; Energy Technology; Energiteknik; Fysik; Physics;

   Abstract : High-cycle thermal fatigue arising from turbulent mixing of non-isothermal flows is a key issue associated with the life management and extension of nuclear power plants. The induced thermal loads and damage are not fully understood yet. READ MORE

4. 2. Using Energy Fluxes to Analyze the Hydrodynamic Performance of Marine Propulsion Systems

   Author : Jennie Andersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Propulsor-Hull interaction; Control volume analysis; RANS; Energy balance analysis; CFD;

   Abstract : The strive towards more fuel efficient ships is a continuously ongoing process, motivated by both economic and regulatory reasons. An important aspects to consider for the final fuel consumption is the propulsion system performance in relevant operating conditions. READ MORE

5. 3. Industrial energy efficiency improvement – the role of policy and evaluation

   Author : Christian Stenqvist; Miljö- och energisystem; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement.; Pulp and paper; Decarbonisation; EU ETS; Energy management; Voluntary Agreement; Evaluation; Policy; Industrial energy efficiency;

   Abstract : At EU and to a varying degree at Member State (MS) level, industrial energy efficiency improvement (EEI) is considered an attractive means for reaching political objectives of different dimensions, not least environmental. For energy-intensive manufacturing industry in particular, EEI can lead to cost reductions, improved profitability and competitiveness. READ MORE

6. 4. Fine particle emissions and slag formation in fixed-bed biomass combustion : aspects of fuel engineering

   Author : Jonathan Fagerström; Christoffer Boman; Dan Boström; Marcus Öhman; Bengt-Johan Skrifvars; Umeå universitet; []
