  5. 4. 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

  7. 5. Optical Diagnostics of Reactive Flows : Application of 3D emission tomography and laser-based methods

    Författare :David Sanned; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2023:Sanned;

    Sammanfattning : Nowadays, numerous specialized systems, ranging from electronics to energy production processes can be found both in science and industry. However due to their specialized nature they often exhibit high sensitivity to intrusive measurements, which can potentially perturb the sought-after characteristics or quantity and consequently compromise overall accuracy.
