  1. 1. Axisymmetric capillary water waves on cylindrical fluid jets

    Master-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Författare :Anna-Mariya Otsetova; [2023]
    Nyckelord :Euler equations; Bernoulli boundary condition; Schauder estimates; nonlinear functional analysis; Mathematics and Statistics;

    Sammanfattning : In their paper, Vanden-Broeck, Miloh and Spivack (Wave Motion 27, 1998) describe two limiting behaviours of irrotational, axisymmetric capillary water waves using numerical methods. They found a two-parameter family of nontrivial solutions. Some solutions of small amplitude approach a uniform stream, while others approach a static configuration. LÄS MER

  3. 2. Global buckling of subsea pipelines with DEH cable

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Anders Meurk; [2022]
    Nyckelord :Solid Mechanics; Global Buckling; Subsea Pipelines; DEH cable; Hållfasthetslära; Global Buckling; Undervattensrörledningar; DEH kabel;

    Sammanfattning : Hydrates, wax, and other fluids forms in cold subsea pipelines which restrict flow of petroleum products during operation. This thesis analyses the global buckling behaviour of subsea pipelines with Direct Electric Heating cables (DEH) through a combination of analytical and FEM simulations. LÄS MER

  4. 3. Prestanda hos värmeväxlande system : Undersökning och utvärdering av värmeväxlare för medicinskt bruk

    M1-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Sara Weman; [2022]
    Nyckelord :Sepsis; Bacteraemia; Heat exchange; Heat transfer; Blood; Milk; Sepsis; Bakteriemi; Värmeväxling; Värmeöverföring; Blod; Mjölk;

    Sammanfattning : Detta examensarbete har genomförts på uppdrag av företaget Sangair i syfte att bidra med kunskap i deras utveckling av en produkt ämnad att behandla sepsis med hjälp av ozon. Sepsis är en av de ledande dödsorsakerna i världen och behandlas idag primärt med antibiotika. LÄS MER

  5. 4. Development of Foot Design for Gasketed Plate Heat Exchangers

    Master-uppsats, Lunds universitet/Innovation

    Författare :Daniel Rundström; [2022]
    Nyckelord :Heat exchanger; bolted joints; product development; FEM.; Technology and Engineering;

    Sammanfattning : In the process of making the industry more energy efficient, the gasketed plate heat exchanger has an important role as it effectively transfers heat between fluids. This master thesis aims to investigate and develop a new supportive foot for Alfa Laval’s gasketed plate heat exchangers. LÄS MER

  7. 5. Epidotization as an Effect of Fluid Rock Interaction, Recorded by a Granitoid From Hågadalen, Uppsala

    Kandidat-uppsats, Uppsala universitet/Mineralogi, petrologi och tektonik

    Författare :Linn Barreby; [2022]
    Nyckelord :Fluids; Fluid Transport; Metamorphism; Metasomatism; Saussuritization; Epidote Group; Geology; Bedrock; Fluider; Fluidtransport; Metamorfos; Metasomatism; Saussuritisering; Epidot Gruppen; Geologi; Berggrund;

    Sammanfattning : A common driving mechanism of metamorphic processes, from which secondary mineralizations and structures develop in a protolith, is known to be a change of the immediate P-T environment that a rock resides in. A factor in this process, which is poorly understood, however, is how the presence of metamorphic fluids in a system, influences the alteration of primary igneous rocks. LÄS MER
