  2. 2. Convection in Loose-fill Attic Insulation

    Author : Paula Wahlgren; Chalmers University of Technology; []
    Keywords : loose-fill insulation; forced convection; attics; natural convection; heat transfer; thermal insulation;

    Abstract : The objective of this study is to investigate the influence of convection on the thermal performance of loose-fill attic insulation under realistic climate conditions. In order to achieve this, a large-scale attic test model has been constructed in a climate chamber. READ MORE

  3. 3. Turbulent Forced Convection Air Cooling of Electronics with Heat Sinks Under Flow Bypass Conditions

    Author : Hans Jonsson; KTH; []
    Keywords : forced convection; heat transfer; pressure drop; turbulent; air cooling; bypass; plate; strip; pin; fin; heat sink; electronics; experimental; numerical; CFD; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Air cooling is still the dominant method for dissipating theheat produced by electronic components. In a typical electronicdevice, the components are situated on a Printed Circuit Board(PCB). For most applications natural convection is sufficientto cool the components. READ MORE

  4. 4. Heat and Mass Transfer in Built Structures - Numerical Analyses

    Author : Jinkai Wang; Chalmers University of Technology; []
    Keywords : air convection; heat; numerical procedure; air and moisture transport; long-term thermal performance; numerical stability; gas-filled foam; thermal aging; simulation;

    Abstract : 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. READ MORE

  5. 5. Natural Convection Heat Transfer in a Horizontal Thermal Insulation Layer Underlying an Air Layer

    Author : Mihail Serkitjis; Chalmers University of Technology; []
    Keywords : air layer; thermal insulation; composite system; heat transfer; numerical simulation; natural convection; porous layer; measurements; testing equipment;

    Abstract : In the thesis a study is made of the influence of natural convection on heat transfer in a composite system comprising a porous material heated from below and an air space situated above this. The measuring apparatus, a Wind Box which has been designed and developed at the Department of Building Physics is described. READ MORE
