  1. 1. Ice load prediction for design of ice-going ships for inland waterways

    Författare :Meng Zhang; Karl Garme; Magnus Burman; Malin Åkermo; Pentti Kujala; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inland waterway ship; ice load; ice conditions; ice properties; FSICR; probabilistic method; ice-hull interaction; numerical model; structural response; finite element analysis; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : With increasing interest in utilizing the inland waterways (IWW) in European countries, the design of IWW vessels gains attention both from a transport efficiency and an emission control point of view. However, unlike in western and central European countries, in Nordic countries, e.g. LÄS MER

  3. 2. Efficient hull design for ice conditions in inland waterways

    Författare :Meng Zhang; Karl Garme; Magnus Burman; Pentti Kujala; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inland waterway ship; ice conditions; ice properties; ice-hull interaction; ice resistance; impact load; numerical method; operation time window; lightweight design; composites and sandwich structure; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : With increasing interest in utilizing the inland waterways (IWW) in European countries, the design of IWW vessels gains attention both from a transport efficiency and an emission control point of view. Usually, IWW ships are designed without ice operation concerns and are structurally weaker than ships designed according to ice-class notifications from the classification societies. LÄS MER

  4. 3. Secondary ice production : An empirical formulation and organization of mechanisms among simulated cloud-types

    Författare :Akash Deshmukh; MERGE: ModElling the Regional and Global Earth system; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ice; collision; ice production; ice enhancement; secondary ice; sublimation; fragmentation;

    Sammanfattning : Clouds are essential elements within Earth's atmosphere, posing a challenge for cloud-resolving models in understanding the creation of new cloud ice particles from existing ice and liquid phases. Such ice initiation determines cloud microphysical and radiative properties, influencing cloud phase, precipitation and cloud extent/properties. LÄS MER

  5. 4. Load Shifting and Storage of Cooling Energy through Ice Bank or Ice Slurry Systems : modelling and experimental analysis
