    Sammanfattning : The press-section of a paper machine holds several different types of press rolls. One of the many press roll variants is the Valmet produced press roll, ViscoNip. This press roll utilizes an extended nip in order to increase the amount of water removed. LÄS MER

  4. 3. A study on topology optimization and cost estimation of fused depostion modelling parts

    Magister-uppsats, Högskolan i Halmstad/Rydberglaboratoriet för tillämpad naturvetenskap (RLAS)

    Författare :prince charuvila thekkethil simon; jibin joseph john; [2020]
    Nyckelord :;

    Sammanfattning : Additive manufacturing (AM) is acquiring a lot of importance in the manufacturing field. It makes the whole manufacturing process easier and effectively brings down the manufacturing cost compared to the traditional methods. It also provides the manufacturer with the freedom of customization according to each customer. LÄS MER

  5. 4. Investigation of the heat transfer of enhanced additively manufactured minichannel heat exchangers

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Hamidreza Rastan; [2019]
    Nyckelord :Minichannel; Microchannel; Heat exchanger; Additive manufacturing; 3D printing; Numerical simulation; CFD; Comsol;

    Sammanfattning : Mini-/microchannel components have received attention over the past few decades owing to their compactness and superior thermal performance. Microchannel heat sinks are typically manufactured through traditional manufacturing practices (milling and sawing, electrodischarge machining, and water jet cutting) by changing their components to work in microscale environments or microfabrication techniques (etching and lost wax molding), which have emerged from the semiconductor industry.
