2. 16. Study of the Apparent Kinetics of Biomass Gasification Using High-Temperature Steam

   Author : Aliaksandr Alevanau; Weihong Yang; Wlodzimierz Blasiak; Anna Ponzio; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high temperature gasification; random pore model; grain model; volumetric model; TGA; Thermal energy engineering; Termisk energiteknik; SRA - Energy; SRA - Energi;

   Abstract : Among the latest achievements in gasification technology, one may list the development of a method to preheat gasification agents using switched ceramic honey combs. The best output from this technology is achieved with use of water steam as a gasification agent, which is heated up to 1600 °C. READ MORE

4. 17. Phase Change Phenomena During Fluid Flow in Microchannels

   Author : Rashid Ali; Björn E Palm; Gian Piero Celata; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microchannels; Boiling; Heat Transfer; Thermal energy engineering; Termisk energiteknik; SRA - Energy; SRA - Energi;

   Abstract : Phase change phenomena of a fluid flowing in a micro channel may be exploited to make the heat exchangers more compact and energy efficient. Compact heat exchangers offer several advantages such as light weight, low cost, energy efficiency, capability of removing high heat fluxes and charge reduction are a few to mention. READ MORE

5. 18. Study into the Potential and Feasibility of a Standalone Solar-Wind Hybrid Electric Energy Supply System

   Author : Getachew Bekele; Björn Palm; Philip Eames; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind Speed; Sunshine Duration; Solar Radiation; Feasibility Study; Standalone System; Solar-Wind Hybrid; Thermal energy engineering; Termisk energiteknik;

   Abstract : The tendency to use renewable energy resources has grown continuouslyover the past few decades, be it due to fear over warnings of globalwarming or because of the depletion and short life of fossil fuels or evenas a result of the interest which has developed among researchers doingscientific research into it. This work can be considered as joining any ofthese groups with an objective of giving electric light to the poorpopulation living in one of the poorest nations in the world. READ MORE

6. 19. Heat Transfer Aspects of Using Phase Change Material in Thermal Energy Storage Applications

   Author : Justin NingWei Chiu; Viktoria Martin; Luisa Cabeza; KTH; []
