  1. 1. Influence of the Substrate on the Internal Flow in Freezing Water Droplets

    Författare :Erik Fagerström; Anna-Lena Ljung; Staffan Lundström; Jasmina Casals-Terré; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internal Flow; Freezing; Water Droplets; Particle Image Velociometry; Strömningslära; Fluid Mechanics;

    Sammanfattning : A water droplet that impacts on a cold surface will start to freeze and in time ice will accumulate. To exemplify, effects of ice accretion is important in areas such as power generation e.g. wind power and vehicles located in a cold climate e. LÄS MER

  3. 2. Quality of Frozen Rainbow Trout. Effects of different freezing and thawing treatments

    Författare :Katarina Nilsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; membrane disintegration; liquid loss; centrifuged tissue fluid; fish; lysosomal enzyme; frozen storage; glazing; freezing; sensory quality; rainbow trout; thawing;

    Sammanfattning : The effects of different freezing, frozen storage and thawing treatments on the muscle tissue of farmed rainbow trout (Oncorhychus mykiss) were studied. Biochemical measurements were correlated to sensory estimated quality changes. The freezing process affects the proteins, the lipid fractions and the membrane structures in the fish muscle. LÄS MER

  7. 5. Experimental studies of ice particle formation with tropospheric relevance

    Författare :Erik Svensson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heterogeneous nucleation; water; freezing; cloud droplets; levitation; electrodynamic balance; light scattering; oxalic acid; kaolinite; dinitrogen pentoxide;

    Sammanfattning : In their fourth assessment report, the Intergovernmental Panel on Climate Change points out the influence of particles suspended in air, known as an aerosol, as the main uncertainty in the understanding of the climate system. Aerosols affect climate in a number of ways. LÄS MER
