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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Heat and Mass Transfer in Built Structures - Numerical Analyses

    Författare :Jinkai Wang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air convection; heat; numerical procedure; air and moisture transport; long-term thermal performance; numerical stability; gas-filled foam; thermal aging; simulation;

    Sammanfattning : Heat and mass transport processes are often present simultaneously in built structures in building applications. The emphasis of this thesis is to contribute to knowledge about predicting the effects of combined heat and mass transport in built structures. LÄS MER

  4. 3. Increased precision in variation simulation by considering effects from temperature and heat

    Författare :Samuel C Lorin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat; robust design; temperature; Varition simulation; welding simulation;

    Sammanfattning : Every manufactured product deviates from the intended product. In a production series a number of noise sources will influence the product resulting in geometric variation. This variation leads to functional and aesthetical variation of the product. LÄS MER

  5. 4. Cold-induced nonshivering thermogenesis : tissue origin, activation, recruitment

    Författare :Valeria Golozoubova; Martin Brand; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; zoofysiologi; Zoological physiology;

    Sammanfattning : Two types of heat production, shivering and nonshivering thermogenesis, are activated in mammals in the cold. In small mammals, nonshivering thermogenesis becomes the main source of heat upon long-term cold exposure. LÄS MER

  7. 5. Heat Transfer in Circulating Fluidized Bed Boilers

    Författare :Claes Breitholtz; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
