  2. 1. Experimental Studies of the Interaction of Atmospheric Aerosol Particles with Clouds and Fogs

    Author : Göran Frank; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; unipolar charger; Physics; DMA; differential mobility analyser; DAA; droplet aerosol analyser; fog microstructure; cloud microstructure; fog droplet; cloud droplet; cloud; fysisk instrumentering; fog; Metrologi; physical instrumentation; Metrology; Kärnfysik; Nuclear physics; Fysik; Fysicumarkivet A:2001:Frank;

    Abstract : In this work, cloud and fog droplet formation was studied in three joint field experiments. The instrument, the droplet aerosol analyser (DAA), has also been further developed and verified as part of this work. The DAA is an instrument especially developed for studies of cloud and fog droplet formation and growth. READ MORE

  4. 2. Development and Test of an Imaging Instrument for Measurement of Water Droplets in Icing Conditions

    Author : Stefani Alita Leona Rydblom; Benny Thörnberg; Aimé Lay-Ekuakille; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Icing measurements; field study; shadowgraph imaging; edge detection; LWC; MVD.;

    Abstract : Structural icing is a persistent challenge for the production of renewable energy from wind. It is mainly caused by supercooled atmospheric droplets of water, which are very common in cold climates. In the most exposed wind parks in Sweden, more than 10 per cent of annual energy production can be lost. READ MORE

  5. 3. Analytical methods for biomolecules involved in atmospheric aerosol formation in the Arctic

    Author : Farshid Mashayekhy Rad; Ulrika Nilsson; Caroline Leck; Leopold Ilag; Peter Haglund; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

    Abstract : In the Arctic, increasing ice-free conditions and nutrients freed from the melting ice must strongly influence the marine life. Aerosol emissions from microbiological marine processes may affect the low clouds and fogs over the summer Arctic, which in turn have effects on the melting of sea ice. READ MORE

  6. 4. Metal fusion using pulsed GasMetal Arc : Melt pool modellingand CFD simulation

    Author : Pradip Aryal; Isabelle Choquet; Muriel Carin; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas metal arc; Electromagnetic force modelling; Free surface deformation; Computational Fluid Dynamics; OpenFOAM; Gasmetallbågsvetsning; Svetsläge; Elektromagnetiskkraftmodellering; Smältytans rörelser; Computational Fluid Dynamics; OpenFOAM; Production Technology; Produktionsteknik;

    Abstract : Pulsed gas metal arc is a highly efficient technique used in manufacturing processes like welding and additive manufacturing. It offers high productivity and cost benefits but it is also prone to defect formation when process parameters are not properly controlled and optimized. READ MORE
