  1. 6. Thermal modelling and evaluation of borehole heat transfer

    Author : Saqib Javed; Lunds universitet.; Lund University.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ground source heat pump; fluid temperature; borehole; short-term; thermal response test; groundwater-filled; optimization; load aggregation; simulation; recovery; step-response; long-term; ground heat exchanger; times; design; ground-coupled;

    Abstract : The use of ground source heat pump systems to provide heating and cooling inbuildings has increased greatly in the last decade or so. These systems have a highpotential for energy efficiency, which has environmental and economicadvantages. READ MORE

  2. 7. Thermal Modeling of Walls, Foundations and Whole Buildings Using Dynamic Thermal Networks

    Author : Eva-Lotta Wentzel; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; walls; weighting functions; Dynamic thermal networks; building; dynamic heat conduction; foundation; step-response functions;

    Abstract : The modeling of the energy balance of buildings is a major task in building physics. A new theory called dynamic thermal networks is under development at the Building Physics Research Group at Chalmers. The calculations are based on step-response functions, and the problems are illustrated in so-called dynamic networks. READ MORE

  3. 8. Some Aspects of Gas Turbine Fuel Preparation and Turbomachinery Response to LCV Fuels

    University dissertation from Energy Sciences, Lund University

    Author : Pontus Eriksson; Lunds universitet.; Lund University.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PDA; LDA; PIV; atomization; spray; off-design; biogas; combustor; biofuel; turbine; Gas turbine; compressor;

    Abstract : This thesis gives some background information on environmental issues as the scientific community at large currently sees it. It tries to relate the plethora of current combustion technologies which may be used in gas turbines to those issues. Some basic principles on combustion design are given. READ MORE

  4. 9. Thermal Modelling of Power Modules in a Hybrid Vehicle Application

    University dissertation from Energy Sciences, Lund University

    Author : Jonas Ottosson; Lunds universitet.; Lund University.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power Module; Thermal Modelling; Electro-Thermal Simulations; Reliability; Cooling requirements;

    Abstract : Hybrid electric and full electric vehicles have attracted growing attention during the last decade. This is a consequence of several factors, such as growing environmental concerns, increasing oil prices and a strive for oil independency. READ MORE

  5. 10. In-situ testing of floating thermal piles in soft sensitive clay

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Anders Bergström; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maintained; Cyclic Thermal loading; Energy piles; Field Test; Thermal Piles;

    Abstract : Thermal piles are structural piles with additional function of working as geothermal heat exchangers towards the soil volume. Heating and cooling process of soft soils is known to affect the stress state and soil structure, with potential consolidation settlements and creep as undesired consequences. READ MORE
