  2. 1. 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. 2. Potential of Ventilation Radiators : Performance evaluation by numerical, analytical and experimental means

    Author : Jonn Are Myhren; Sture Holmberg; Per Olaf Tjelflaat; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ventilation radiator; thermal comfort; exhaust ventilation; CFD; energy saving; convection fin; low temperature heating; Building engineering; Byggnadsteknik;

    Abstract : Energy consumption for heating and ventilation of buildings is still in 2011considered far too high, but there are many ways to save energy and construct lowenergy buildings that have not been fully utilised. This doctoral thesis has focused onone of these - low temperature heating systems. READ MORE

  5. 3. Numerical Modelling of Some Engineering Heat Transfer Problems

    Author : Daniel Eriksson; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy research; Energiforskning;

    Abstract : Engineering heat transfer problems are very often of a complex nature and most often no analytical solutions exist. One way to create solutions to such problems is to apply numerical methods. This study concerns heat transfer problems with coupled conduction, convection and thermal radiation. READ MORE
