  1. 1. Interception evaporation processes and measurement techniques

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Angela Lundberg; Luleå tekniska universitet.; [1996]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : In temperate regions, evaporation of water intercepted by the vegetation represents an important part of the evapotranspiration. A review of interception evaporation studies showed that knowledge about interception evaporation processes is limited and progress is hampered by technical difficulties. LÄS MER

  2. 2. Detailed simulations of droplet evaporation

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Giandomenico Lupo; KTH.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; droplet; evaporation; phase change; multicomponent; immersed boundary; droppe; förångning; fasövergång; multikomponent; nedsånkt rand;

    Sammanfattning : Droplet evaporation (and condensation) is one of the most common instancesof multiphase flow with phase change, encountered in nature as well as intechnical and industrial applications. Examples include falling rain drops, fogsand mists, aerosol applications like electronic cigarettes and inhalation drugdelivery, engineering applications like spray combustion, spray wet scrubbing orgas absorption, spray drying, flame spray pyrolysis.

  3. 3. Energy Efficient Evaporation in Future Kraft Pulp Mills

    Detta är en avhandling från Chalmers University of Technology

    Författare :Jessica Algehed; Chalmers tekniska högskola.; Chalmers University of Technology.; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; black liquor; economics; energy; evaporation; excess heat; pinch technology; process integration; pulp and paper; wastewater;

    Sammanfattning : In the future, the technical and economic conditions for energy savings in the pulp and paper industry will change. More excess heat will be available in future mills above 80°C than in existing mills, increasing the potential for process integration, and governmental actions for reducing CO2 emissions and the deregulation of electricity markets will change the economic conditions for investments aimed at saving energy.

    Sammanfattning : The evaporation plant is one of the major steam consumers in kraft pulp mills, which are the dominant type of chemical pulp mill in Sweden. Previous studies have shown potential to decrease the live steam demand for the pulp process, e.g. LÄS MER

  5. 5. Heat transfer in falling film evaporation of black liquor - Experiments and theory

    Detta är en avhandling från Chalmers University of Technology

    Författare :Miriam Johansson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemisk energiteknik; Chemical energy engineering; Heat transfer; black liquor; evaporation; evaporator; falling film; experimental; correlations; viscosity; non-Newtonian; kraft pulp mill;

    Sammanfattning : Pulp and paper industry uses a large part of the total amount of energy in industry in Sweden. The evaporation plant has the major energy demand in the kraft pulp mill, which is the dominant type of chemical pulp mill. Previous studies have shown potential to decrease the live steam demand for the pulp process, e.g. LÄS MER
