  2. 11. On Aircraft Development : managing complex systems with long life cycles

    Author : Gunnar Holmberg; Earll Murman; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Time plays an important role for the development of aircraft. The aircraft has a long life cycle and is composed of many systems with life cycles that sometimes differ with an order of magnitude in relation to the overall system. READ MORE

  4. 12. Integrating Biomass in Existing Natural Gas-Fired Power Plants

    Author : Erik Pihl; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forest Residue; Modeling; Hybrid Combined Cycles; Biomass; Gasification; Efficiency;

    Abstract : Using biomass for utility heat and electricity generation can supplement use of fossil fuels, whose emissions of carbon dioxide likely risk causing serious climate change and ocean acidification. Biomass as energy source is a limited resource and when used as fuel in thermal power plants this currently results in higher production costs than using fossil fuels such as natural gas and coal.

  5. 13. 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

  6. 14. Thermodynamic Cycles using Carbon Dioxide as Working Fluid : CO2 transcritical power cycle study

    Author : Chen Yang; Lundqvist Per; Carlos Infante Ferreria; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The interest in utilizing the energy in low‐grade heat sources and waste heat is increasing. There is an abundance of such heat sources, but their utilization today is insufficient, mainly due to the limitations of the conventional power cycles in such applications, such as low efficiency, bulky size or moisture at the expansion outlet (e.g. READ MORE

  7. 15. Advanced power cycles with mixture as the working fluid

    Author : Maria Jonsson; KTH; []
    Keywords : power cycle; mixture working fluid; Kalina cycle; ammonia-water mixture; reciprocating internal combustion engine; bottoming cycle; gas turbine; evaporative gas turbine; air-water mixture; exergy;

    Abstract : The world demand for electrical power increasescontinuously, requiring efficient and low-cost methods forpower generation. This thesis investigates two advanced powercycles with mixtures as the working fluid: the Kalina cycle,alternatively called the ammonia-water cycle, and theevaporative gas turbine cycle. READ MORE
