  1. 1. Centrifugal Turbopumps - Flow Physics and Modelling

    University essay from Lunds universitet/Institutionen för energivetenskaper

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

    Abstract : 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. READ MORE

  3. 2. 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

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser; Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Abstract : 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.

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

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

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

    Abstract : 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. READ MORE

  5. 4. Influence of Building Structure and Building Content on Residential Fires

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Hilco Hiemstra; [2016]
    Keywords : Residential fires; Building structure; Building content; Insulation; Technology and Engineering;

    Abstract : In Europe, there are still a significant amount of residential fires. Particularly fires in the living room are a major threat to the occupants. Much research has been done to residential fires. READ MORE

  6. 5. Modeling of NOx formation in heavy duty engines

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Kenan Muric; [2011]
    Keywords : Technology and Engineering;

    Abstract : In order to apply combustion feedback control in diesel engines to control pollution formation, good models are needed to estimate the states. One of those would be NOx levels which are regulated by European law. There are conventional sensors on the market that can measure NOx but these are too slow for in-cycle feedback control. READ MORE
