  2. 6. Experimental and numerical evaluation of heat transfer in the press hardening process

    Author : Per Salomonsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : In recent decades, the use of high- and ultra high strength steels in modern car bodies has increased drastically. This is due to both severe legislation of passenger passive safety and the recent year's effort to reduce fuel consumption to decrease environmental harmful emissions. READ MORE

  4. 7. Experimental and analytical study of thermal mixing at reactor conditions

    Author : Mattia Bergagio; Henryk Anglart; Horst-Michael Prasser; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-cycle thermal fatigue; Hilbert-Huang transform; large eddy; WALE; rainflow; inverse heat conduction; adjoint conjugate gradient; Energy Technology; Energiteknik; Fysik; Physics;

    Abstract : High-cycle thermal fatigue due to turbulent mixing of streams at distinct temperatures is an interdisciplinary issue affecting safety and life extension of existing reactors together with the design of new reactors. It is challenging to model damage and thermal loads arising from the above mixing. READ MORE

    Abstract : Diesel engines are known to be a major source of a highly pollutant material known as particulate matter, PM, which is a strongly threatening agent to human health. Therefore, diesel particulate filters are used to reduce PM emissions by trapping soot. READ MORE

  7. 10. Development of an Impinging Receiver for Solar Dish-Brayton Systems

    Author : Wujun Wang; Björn Laumert; Torsten Fransson; Torsten Strand; Uwe Gampe; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concentrating solar power; Impinging receiver; Inverse design method; Conjugate heat transfer; High flux solar simulator; Energiteknik; Energy Technology;

    Abstract : A new receiver concept utilizing impinging jet cooling technology has been developed for a small scale solar dish-Brayton system. In a typical impinging receiver design, the jet nozzles are distributed evenly around the cylindrical absorber wall above the solar peak flux region for managing the temperature at an acceptable level.
