  1. 1. Effect of infill density on mechanical and fire properties of polylactic acid composites produced by FDM 3D-printing technology

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

    Författare :David Aronsson Edström; Oskar Lundberg; [2022]
    Nyckelord :3D-printing; FDM; PLA; fire; fire engineering; cone calorimeter; tensile test; UL-94;

    Sammanfattning : 3D-printing is a new and upcoming manufacturing technique that can significantly reduce time and material losses in production. Fused deposition modeling (FDM) is one of the most commonly used 3D-printing methods for processing conventional thermoplastic polymers. LÄS MER

  2. 2. Simulating cable fires in Fire Dynamics Simulator : Based on small scale testing in cone calorimeter

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

    Författare :Hugo Zacharoff; [2021]
    Nyckelord :Cable fires; FDS; cone calorimeter;

    Sammanfattning : In a society increasingly more influenced by technology and electricity, electrical and computer cables will play a more vital role in humans’ everyday life. With an increasing number of cables being introduced into society, the risk of fires caused by or involving cables will increase and become a more common danger to property and human lives. LÄS MER

  3. 3. LES modelling of spray combustion

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Arvid Åkerblom; [2021]
    Nyckelord :Gas Turbine; CFD; Large Eddy Simulation; Lagrangian Particle Tracking; Chemical Kinetics; Reaction Mechanism; Combustion; OpenFOAM; CHEMKIN; Technology and Engineering;

    Sammanfattning : Computational fluid dynamics is a powerful method for understanding the flow and combustion that occurs inside aircraft engines and will be a key tool in the transition from conventional fossil-based fuel to sustainable alternatives. Because conventional fuels have been more widely researched, an attempt at simulating the combustion of alternative fuels should be preceded by the development of a method that is capable of accurately simulating the combustion of a conventional fuel.

  4. 4. Design Development of a Hydrostat : Construction of a hydrostat used in an underwater SAI-unit

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Abbas Mohammadi; [2021]
    Nyckelord :Hydrostat; Saab Dynamics; Design; UNNDEX; Pressure;

    Sammanfattning : Working with and providing different military and industrial solutions, SBD’s (Saab Dynamic) work also involve underwater equipment and underwater weapon (UW) systems. Nowadays, there are a number of standards that should be followed to make weapon systems safe to use, transport and handle. LÄS MER

  5. 5. Computer vision for automatic opening of fuming slag-furnace

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Hannes Burman; [2021]
    Nyckelord :Computer vision;

    Sammanfattning : This thesis covers the implementation of visual algorithms for a robot that is to operate at a smelter furnace. The goal is for the robot to replace a human in the opening, closing and flow regulation process as danger can arise when 1300°C slag flows out of the furnace. LÄS MER
