1. 1. Interception evaporation : processes and measurement techniques

   Författare :Angela Lundberg; Luleå tekniska universitet; []
   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

3. 2. Detailed simulations of droplet evaporation

   Författare :Giandomenico Lupo; Christophe Duwig; KTH; []
   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.

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

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

   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.

5. 4. Heat Transfer and Hydrodynamics in Falling Film Evaporation of Black Liquor

   Författare :Miriam Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; correlation; black liquor; turbulence; hydrodynamics; kraft pulp mill; falling film; Heat transfer; evaporation; experimental; evaporator;

   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

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

   Författare :Miriam Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; evaporator; black liquor; falling film; kraft pulp mill; Heat transfer; evaporation; viscosity; correlations; experimental; non-Newtonian;

   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
