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

3. 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.

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

   Detta är en avhandling från KTH Royal Institute of Technology

   Författare :Miriam Johansson; [2008]
   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

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

   Detta är en avhandling från KTH Royal Institute of Technology

   Författare :Miriam Johansson; [2006]
   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

7. 5. Process modelling based on data from an evaporation and a CTMP process : Analysis of energy efficiency and process variability

   Detta är en avhandling från Karlstad : Karlstads universitet

   Författare :Daniel Ekbåge; Karlstads universitet.; [2018]
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CTMP; process modelling; evaporation; energy efficiency; Miljö- och energisystem; Environmental and Energy Systems;

   Sammanfattning : The manufacture of pulp and paper is an energy intensive process configured of several unit processes that shape a network of flows of wood chips, chemical pulp, mechanical pulp, paperboard, steam and other important components. Improved energy efficiency supports sustainability of the process and the products. LÄS MER
