  1. 1. Sprinklers påverkan på ventilationsbrandskydd : En funktionsanalys avseesnde sprinklers påverkan på brandgasspridning i hotellmiljö.

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Byggkonstruktion och brand; Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Erik Rönnberg; Elias Björnqvist; [2020]
    Nyckelord :Sprinkler; brandgasspridning; hotell; brandskydd; FDS; PFS;

    Sammanfattning : The fact that a building is covered by a well-arranged fire protection is today a basic precondition for the safety of a building. Good and organized fire protection is also an essential part of a good safety culture. LÄS MER

  2. 2. Numerical modelling for characterization of the granular flows impact on the gas flow in a packed-bed-reactor

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Anton Sundström; [2020]
    Nyckelord :DEM; Discrete element method;

    Sammanfattning : The goal of the project was to characterize the granular flows impact on the gas flow in a packed-bed-reactor. The study was created at Swerim as a master's thesis for Luleå University of Technology. The packed-bed-reactor geometry used in this study is a scaled down blast furnace model. LÄS MER

  3. 3. Numerical Study on Air Demand of Free Surface Flows in a Discharge Tunnel

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Jonathan Barassa; Rickard Nordlöf; [2020]
    Nyckelord :Computational Fluid mechanics; Hydropower; Air demand; Free surface flows; ANSYS Fluent;

    Sammanfattning : Aeration issued through a ventilation shaft is an important measure to prevent cavitation and large gauge pressure in flood discharge tunnels. In order to dimension the ventilation shaft appropriately, itis necessary to have a good understanding of the air-water flow in the tunnel. LÄS MER

  4. 4. Neural Network Based Model Predictive Control of Turbulent Gas-Solid Corner Flow

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Simon Wredh; [2020]
    Nyckelord :computational fluid dynamics; machine learning; system identification; control theory; multi-phase flow; gas-solid flow; rans; lagrangian particle tracking; neural network; model predictive control; bio-aerosol;

    Sammanfattning : Over the past decades, attention has been brought to the importance of indoor air quality and the serious threat of bio-aerosol contamination towards human health. A novel idea to transport hazardous particles away from sensitive areas is to automatically control bio-aerosol concentrations, by utilising airflows from ventilation systems. LÄS MER

  5. 5. Additively Manufactured Heat Exchangers- Development and Testing

    Master-uppsats, Lunds universitet/Produktutveckling

    Författare :Isak Wadsö; Simon Holmqvist; [2020]
    Nyckelord :Additive manufacturing; Heat exchanger; Triply periodic minimal surface; AlSi10Mg; Technology and Engineering;

    Sammanfattning : Heat exchangers are important devices in many applications. Extensive work is done in optimization, but the overall designs are often one of the conventional varieties such as plate or shell-and-tube heat exchanger. These are constrained by their manufacturing, for example the use of construction material such as sheet metal and cylindrical pipes. LÄS MER
