  1. 11. Design, Optimization and Evaluation of a Transonic Aeroelastic Rig

    Author : Simeng Tian; Andrew R. Martin; Mauricio Gutierrez Salas; Dieter Peitsch; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transonic compressor; Aeroelastic rig; Design; CFD; Unsteady flow; Energiteknik; Energy Technology;

    Abstract : The compressor is one of the most essential components of a modern turbomachinery engine. This component is exposed to vibrations that without proper design can damage structural integrity and lead to failure. READ MORE

  2. 12. Experimental and numerical study of the thermal and hydraulic effect of EMC screens in radio base stations : detailed and compact models

    Author : Raúl Antón Remírez; Björn Palm; Masud Behnia; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sub-rack; perforated plate; air cooling; 90 degrees turn; flow deistribution; CFD; measurement; Mechanical energy engineering; Mekanisk energiteknik;

    Abstract : Today’s telecommunication cabinets use Electro Magnetic Compliance (EMC) screens in order to reduce electromagnetic noise that can cause some miss functions in electronic equipment. Many radio base stations (RBSs) use a 90-degree building architecture: the flow inlet is perpendicular to the EMC screen, which creates a complex flow, with a 90-degree air turn, expansions, compressions, perforated plates and PCBs.

  3. 13. Responsible resource management in hotels : attitudes, indicators, tools and strategies

    Author : Paulina Bohdanowicz; Björn Palm; Ivo Martinac; Walter Jamieson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hotels; energy and water management; energy and water conservation; environmental awareness; environmental reporting; performance indicators; consumption modelling; benchmarking; Mechanical energy engineering; Mekanisk energiteknik;

    Abstract : Hotels constitute one of the main, and still expanding, pillars of the tourism sector and are highly unique among other commercial buildings. Resource intensive and frequently inefficient systems and operational routines applied in the sector, result in considerable environmental impact and indicate an urgent need for more environmentally sound practices and products in the hotel industry.

  4. 14. Novel cycles using carbon dioxide as working fluid : new ways to utilize energy from low-grade heat sources

    Author : Yang Chen; Per Gunnar Lundqvist; Mats Westermark; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal energy engineering; Termisk energiteknik;

    Abstract : This licentiate thesis proposes and analyzes three carbon dioxide novel cycles, namely: the carbon dioxide transcritical power cycle, the carbon dioxide Brayton cycle and the carbon dioxide cooling and power combined cycle. Due to the different characteristics of each cycle, the three cycles are suitable for different applications. READ MORE
