1. 1. Combustion of agricultural residues : Application for Stirling micro-combined heat and power

   Författare :Evelyn Cardozo; Torsten Torsten Fransson; Carlos Augusto Santos Silva; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology;

   Sammanfattning : Access to energy services is crucial for the development of countries. Therefore, in developing countries, the access to modern conversion technologies would contribute to reduce the poverty, improve health services and promote the economy especially in rural areas. Around 2.5 billion people in these countries use biomass for cooking. LÄS MER

3. 2. Development of an Impinging Receiver for Solar Dish-Brayton Systems

   Författare :Wujun Wang; Björn Laumert; Torsten Fransson; Torsten Strand; Uwe Gampe; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concentrating solar power; Impinging receiver; Inverse design method; Conjugate heat transfer; High flux solar simulator; Energiteknik; Energy Technology;

   Sammanfattning : A new receiver concept utilizing impinging jet cooling technology has been developed for a small scale solar dish-Brayton system. In a typical impinging receiver design, the jet nozzles are distributed evenly around the cylindrical absorber wall above the solar peak flux region for managing the temperature at an acceptable level.

7. 5. Numerical Analysis of Partial Admission in Axial Turbines

   Författare :Narmin Baagherzadeh Hushmandi; Torsten H. Fransson; Liping Xu; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical energy engineering; Mekanisk energiteknik;

   Sammanfattning : HTML clipboard Numerical analysis of partial admission in axial turbines is performed in this work. Geometrical details of an existing two stage turbine facility with low reaction blades is used for this purpose. For validation of the numerical results, experimental measurements of one partial admission configuration at design point was used. LÄS MER
