  1. 1. In the Pipe or End of Pipe? Transport and Dispersion of Water-borne Pollutants and Feasibility of Abatement Measures

    University dissertation from KTH Royal Institute of Technology

    Author : Christoffer Carstens; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Contaminant transport modelling; Groundwater; Dispersion; Wave power; Eutrophication;

    Abstract : Eutrophication is one of the key environmental problems of today, both in terms of complexity and magnitude. For the Baltic Sea (BS), eutrophication is an acute problem, leading to hypoxic conditions at the bottom; a situation that is sustained and amplified, when phosphorus is released from hypoxic sediments.

  2. 2. 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.

  3. 3. Dissolved Air Flotation

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Mia Bondelind; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; two- and three-dimensional; Dissolved Air Flotation DAF ; aggregation model; Computational Fluid Dynamics CFD ; field study; surface forces; turbulence; single and multiphase flow;

    Abstract : Dissolved Air Flotation (DAF) is a well-established treatment method for water containing low density particles. The density-driven process is operated by the injection of water saturated with air under high pressure. At the pressure reduction microscopic air bubbles are formed. READ MORE

  4. 4. Thermal response test numerical simulations and analyses

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Anna-Maria Gustafsson; Luleå tekniska universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering; VA-teknik; Urban Water Engineering;

    Abstract : When constructing large borehole heat exchanger (BHE) systems, bedrock and borehole thermal properties are vital for a good design. Today's design programs presume conductive heat transfer in both borehole and bedrock. READ MORE

  5. 5. A multi-resolution approach for modeling flow and solute transport in heterogeneous porous media

    University dissertation from Stockholm : KTH

    Author : Hrvoje Gotovac; KTH.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-resolution adaptive approach; Atomic and Fup basis functions; Monte- Carlo method; Heterogeneous porous media; Flow; Transport; Travel time; TECHNOLOGY Civil engineering and architecture Water engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Vattenteknik;

    Abstract : Subsurface processes are usually characterized by rare field experiments, sparse measurements,multi-resolution interpretations, stochastic description, related uncertainties and computational complexity. Over the last few decades, different computational techniques and strategies have become indispensable tools for flow and solute transport prediction in heterogeneous porousmedia. READ MORE
