    Abstract : The challenge of achieving global sanitation targets is that it requires application of both technology that is appropriate and a supporting organizational structure. The interactions between the two begin during the planning/decision-making process and continue throughout the system lifetime. READ MORE

  5. 5. Thermal response tests influence of convective flow in groundwater filled borehole heat exchanger

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Anna-Maria Gustafsson; Luleå tekniska universitet.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil engineering and architecture - Water engineering; Samhällsbyggnadsteknik och arkitektur - Vattenteknik; Vattenteknik; Water Resources Engineering; VA-teknik; Urban Water Engineering;

    Abstract : The main objective of this doctorial thesis was to investigate how thermally induced movements in the groundwater (natural convective flow) may influence the heat transport in borehole and surrounding bedrock in a groundwater filled borehole heat exchanger system. The purpose was also to determine if thermal response tests could be used to detect the convective influence and the effect on evaluated heat transfer parameters, effective bedrock thermal conductivity and borehole thermal resistance.
