  1. 1. EVALUATION OF MULTI-ZONE MODELLING FOR FIRE RISK ASSESSMENT IN TUNNELS

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Annachiara Nardone; [2023]
    Nyckelord :tunnels; tunnel fires; multi-zone modelling; Technology and Engineering;

    Sammanfattning : Abstract Tunnels are one of the most complex and delicate elements of the road system. Assessing fire behaviour and fire severity remains the biggest source of uncertainty in risk assessment and is an essential step in the tunnel design process. LÄS MER

  3. 2. Centrifugal Turbopumps - Flow Physics and Modelling

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Carl Eriksson; Hampus Henåker; [2021]
    Nyckelord :Centrifugal Pumps; Rocket Science; Turbopumps; Two-Zone Model; Impeller; Vaneless Diffuser; Vaned Diffuser; Technology and Engineering;

    Sammanfattning : Choices made in the early stages of a design process are crucial. They dictate many of the limitations and freedoms the designer has in later stages of the design. Informed decisions are therefore crucial at this stage. LÄS MER

  4. 3. Influence of ventilation on ro-ro space fire development : A study using two-zone fire models in order to explore tendencies of how different ventilation parameters affects the fire development in a ro-ro space

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Martin Lindgren; Andreas Lilja; [2019]
    Nyckelord :Fire; Ro-ro space; Ventilation; Simulation; Two-zone model; Brand; Rorolastutrymme; Ventilation; Simulering; Tvåzonsmodell;

    Sammanfattning : A ship to which vehicles and other loads can be rolled on and off is usually named ro-ro ship. A ro-ro ship consists of large corridor shaped space, normally extending to a considerable length or the entire length of the ship, which is usually loaded with various vehicles or stowage units.

  7. 5. Thermal Exposure Caused by the Smoke Gas Layer in Pre-flashover Fires : A Two-zone Model Approach

    M1-uppsats, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Lucas Andersson; [2016]
    Nyckelord :Thermal exposure; smoke gas layer; two-zone model;

    Sammanfattning : A pre-flashover fire is very different from a post-flashover fire. The main difference is that in a pre-flashover fire the gas temperature and the radiation temperature differ. One thing that makes it a lot different is that the thermal exposure induced by a pre-flashover fire is largely affected by the smoke gas layer. LÄS MER
