  2. 11. Perspectives of Aerodynamic Drag and Cooling Airflow for Heavy-Duty Trucks - Reconsidering European Total Length Legislation

    Author : Helena Martini; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cooling airflow; CFD; under-hood design; soft nose; truck-trailer combinations; inlet duct; outlet duct; aerodynamic drag;

    Abstract : Increasing fuel prices and constantly lowered emission legislation forces the vehicle industry to develop new methods for propelling vehicles and to optimize existing technology. Trucks constitute a significant proportion of the transportation system; consequently it is of great importance to ensure as low an impact as possible on the environment. READ MORE

  4. 12. High-Capacity Cool Thermal Energy Storage for Peak Shaving - a Solution for Energy Challenges in the 21st century

    Author : Bo He; KTH; []
    Keywords : Comfort cooling; peak shaving; phase change materials PCM ; cool thermal energy storage; DSC; phase change temperature; the heat of fusion; phase equilibrium; phase diagram.;

    Abstract : Due to climatic change, increasing thermal loads inbuildings and rising living standards, comfort cooling inbuildings is becoming increasingly important and the demand forcomfort cooling is expanding very quickly around the world. Theincreased cooling demand results in a peak in electrical powerdemand during the hottest summer hours. READ MORE

  5. 13. Testing large samples of PCM in water calorimeter and PCM used in room applications by night-air cooling

    Author : Rickard Bellander; Ove Söderström; Gudni Jóhannesson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-change material; PCM; water calorimeter; air heat exchanger; durability; thermal properties; heat capacity; Building engineering; Byggnadsteknik;

    Abstract : The latent-heat-storage capacity in Phase-Change Materials can be used for storing or releasing energy within a small temperature interval. Upon the phase transition taking place in a narrow temperature span, the material takes up or releases more energy compared to sensible heat storage. READ MORE

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

    Author : Justin NingWei Chiu; Viktoria Martin; Luisa Cabeza; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal energy storage; comfort cooling; phase change materials; heat transfer; Thermal energy engineering; Termisk energiteknik; Other materials science; Övrig teknisk materialvetenskap; Environmental engineering; Miljöteknik; SRA - Energy; SRA - Energi;

    Abstract : Innovative methods for providing sustainable heating and cooling through thermal energy storage (TES) have gained increasing attention as heating and cooling demands in the built environment continue to climb. As energy prices continue to soar and systems reach their maximal capacity, there is an urgent need for alternatives to alleviate peak energy use. READ MORE

  7. 15. Thermal Modelling of Power Modules in a Hybrid Vehicle Application

    Author : Jonas Ottosson; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power Module; Thermal Modelling; Electro-Thermal Simulations; Reliability; Cooling requirements;

    Abstract : Hybrid electric and full electric vehicles have attracted growing attention during the last decade. This is a consequence of several factors, such as growing environmental concerns, increasing oil prices and a strive for oil independency. READ MORE
