  3. 27. A Rational Exergy Management Model to Curb CO2 Emissions in the Exergy-Aware Built Environments of the Future

    Författare :Siir Kilkis; Folke Björk; Bahram Moshfegh; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Exergy; CO2 emissions; built environment; buildings; energy system; scenario-based analysis; mitigation strategies; net-zero; LEED; energy transition; transition management; SRA - Energy; SRA - Energi;

    Sammanfattning : This thesis puts forth the means of a strategic approach to address a persistent problem in the energy system and in this way, to transition the built environment to a future state that is more exergy-aware to curb CO2 emissions. Such a vision is made possible by the six-fold contributions of the research work: I) An analytical model is developed, which for the first time, formulates the CO2 emissions that are compounded in the energy system as a function of the systematic failures to match the supply and demand of exergy.

  4. 28. Methods for Characterization of the Diesel Combustion and Emission Formation Processes

    Författare :Mikael Lindström; Hans-Erik Ångström; Werner Hentschel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diesel engine emissions; SRA - Energy; SRA - Energi;

    Sammanfattning : In this thesis various aspects of the diesel engine fuel injection, combustion and emission formation processes have been evaluated. Several types of evaluation tools and methods have been applied. Fuel spray momentum was used to characterize injection rate and hole-to-hole variations in fuel injectors. LÄS MER
