  2. 1. Reduction of heat transfer and heat load in internal combustion engines

    Author : Joop Somhorst; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; efficiency; TBC; thermal barrier coating; surface roughness; engine; heat transfer; emissions; alumina; zirconia;

    Abstract : Thermal insulation of the combustion chamber in an engine has great potential to reduce fuel consumption and CO2 emissions. Research on thermal barrier coatings (TBC) has been performed since the early eighties to address this potential. READ MORE

  4. 2. Condensation irrigation : simulations of heat and mass transfer

    Author : Jenny Lindblom; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : There is a growing water demand in the world. Along with the deterioration of existing water supplies, the escalating world population leads to the assumption that two out of three people will lack sufficient freshwater by the year 2025. READ MORE

  5. 3. On Heat and Paper : From Hot Pressing to Impulse Technology

    Author : Marco Francesco Carlo Lucisano; KTH; []
    Keywords : Paper; Impulse Drying; Heat Transfer; Phase Change; Heat-Pipe Effect; Delamination; Flashing;

    Abstract : Impulse technology is a process in which water is removedfrom a wet paper web by the combined action of mechanicalpressure and intense heat. This results in increased dewateringrates, increased smoothness on the roll side of the sheet, andincreased density. READ MORE

  6. 4. On-Engine Turbocharger Performance Considering Heat Transfer

    Author : Habib Aghaali; Hans-Erik Ångström; Jose R. Serrrano; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbocharger; Internal combustion engine; heat transfer; turbocharged engine; on-engine turbocharger; turbocharger performance; توربو شارژر، موتور احتراق داخلی، انتقال حرارت، توربوچارجر; turbo; turboladdare; förbränningsmotor; värmeöverföring; turboladdad motor;

    Abstract : Heat transfer plays an important role in affecting an on-engine turbocharger performance. However, it is normally not taken into account for turbocharged engine simulations. READ MORE

  7. 5. Heat Transfer in Circulating Fluidized Bed Boilers

    Author : Claes Breitholtz; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; similarity; char; heat transfer; tube wall; circulating fluidized bed; particle; radiation; scaling; particle convection; gas convection;

    Abstract : Heat transfer to single particles in the transport zone of circulating fluidized beds and heat transfer to membrane tube walls have been investigated. The heat transfer coefficient to spheres in the transport zone of a circulating fluidized bed boiler has been measured with dark and light calorimeters. READ MORE
