  1. 1. Numerical experiments - a research method in fire science

    Detta är en avhandling från Department of Fire Safety Engineering and Systems Safety, Lund University

    Författare :Nils Johansson; Lunds universitet.; Lund University.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; experimental uncertainty; accuracy; fire dynamics; compartment fires; models; experiments; Numerical experiments;

    Sammanfattning : Fires are complex and it is hard to derive relationships from theory in fire science. Full-scale and small-scale experiments have been used with great success in order to increase the understanding of fire chemistry and fire dynamics. But, there are shortcomings and difficulties with conducting these traditional fire experiments. LÄS MER

    Sammanfattning : High-Power Microwaves (HPM) can be used to intentionally disturb or destroy electronic equipment at a distance by inducing high voltages and currents. This thesis presents results from experiments with a narrow band HPM source, the vircator. LÄS MER

  3. 3. Molecular structure and dynamics of liquid water Simulations complementing experiments

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Författare :Daniel Schlesinger; Stockholms universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; liquid water; supercooled water; molecular simulation; evaporative cooling; Theoretical Physics; teoretisk fysik;

    Sammanfattning : Water is abundant on earth and in the atmosphere and the most crucial liquid for life as we know it. It has been subject to rather intense research since more than a century and still holds secrets about its molecular structure and dynamics, particularly in the supercooled state, i. e. the metastable liquid below its melting point.

  4. 4. Phosphorus transport and reduction in compact-bed filters simulations and experiments

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Amir Jourak; Luleå tekniska universitet.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Excessive release of phosphorus from the effluent of on-site sanitation facilities to the environment is one source of aquatic pollution. The primary effect of excess phosphorus in the aquatic environment is eutrophication. LÄS MER

  5. 5. Compression moulding of SMC experiments and simulation

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Jimmy Olsson; Luleå tekniska universitet.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Due to excellent properties and relatively low material and manufacturing costs, the use of fibre reinforced polymer composites have increased during the last decades. One method that is suitable for large scale productions of e.g. lightweight vehicle components is compression moulding of sheet moulding compound (SMC). LÄS MER
