  1. 1. Approaches for improving the rheological characterization of fermented dairy products

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Abdulrahman Muhammad; [2020]
    Nyckelord :food engineering; livsmedelsteknik; Technology and Engineering;

    Sammanfattning : Fermented dairy products are wildly consumable products in today societies, and these products are known for their unique rheological properties due to the complex structural systems they possess. The simplest rheological model for describing yogurt behavior is the Power Law model, but this model parameters are not sufficient for describing the complex behavior during flow and filling.

  2. 2. The verification and validation of a probabilistic risk analysis method for road tunnels

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Kim Genberg; Karin Sandin; [2020]
    Nyckelord :Tunnels; fire; evacuation; probabilistic risk analysis; QRA; verification and validation; Technology and Engineering;

    Sammanfattning : In this thesis, a new probabilistic risk assessment tool for road tunnels has been verified and validated. The verification and validation were performed along with a literature review to find different key variables that affect the risk in a road tunnel and find out how these variables can be handled.

    Sammanfattning : Saab Kockums AB has been tasked by the Swedish Armed Forces to develop a new submarine model named A26. This task poses many challenges, one of which being the design of the fire protection on the submarine. LÄS MER

  4. 4. CFD-simulering av hydrofoil för ett flytande vindkraftverk : Dimensionering av hydrofoil för användning i ett vertikalaxlat flytande vindkraftverk

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Hampus Hultgren; [2020]
    Nyckelord :;

    Sammanfattning : In this master thesis computational fluid dynamics simulations areconducted to dimension a hydrofoil to be used in a floating windturbine designed by Manta Wind. The simulations are made with thesoftware SolidWorks flow simulation. LÄS MER

  5. 5. Steady ideal flows with vorticity in toroidal domains and periodic cylinders

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

    Författare :Gustav Jillbratt; [2020]
    Nyckelord :Partial differential equations; Euler equation; Vorticity; Fluid dynamics; Mathematics and Statistics;

    Sammanfattning : In a paper from 1970, Lortz constructs rotational solutions to the steady Euler equation in toroidal domains using a fixed point method. We shall review this method and rewrite it using Banach's fixed point theorem. LÄS MER
