  1. 21. Accelerating Fluids Simulation Using SPH and Implementation on GPU

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Aditya Hendra; [2015]
    Nyckelord :;

    Sammanfattning : Fluids simulation is usually done with CFD methods which offers high precision but needs days/weeks/months to compute on desktop CPUs which limits the practical use in industrial control systems. In order to reduce the computation time Smoothed Particle Hydrodynamics (SPH) method is used. LÄS MER

  3. 22. Jet flow simulations of Baihetan hydropower station’s discharge surface spillways

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

    Författare :Benjamin Blomqvist; Britta Rönntoft; [2015]
    Nyckelord :CFD; Baihetan; spillway; hydropower;

    Sammanfattning : This project was performed in order to determine if numerical simulations can be used to predict the spreading of a water jet that exits the discharge surface spillways of Baihetan hydropower station. If the spreading ranges can be predicted correctly using numerical simulations, the pressure distribution in the plunge pool downstream the dam can be determined. LÄS MER

  4. 23. Procedur för delning av casing offshore med hjälp av vattenskärning

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

    Författare :Patrik Söderwall; [2015]
    Nyckelord :Abrasive waterjet cutting; Abrasiv vattenskärning;

    Sammanfattning : Within the oil and gas industry on offshore installations in the North Sea, several oil wells are closing in on the brink where they no longer are being profitable to keep producing from. When that day comes the oil wells are closed off and the boreholes are plugged with cement. LÄS MER

  5. 24. Integration of an industrial robot and a CNC machine in waterjet cutting application.

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Mateusz Jozko; Jaroslaw Rykaczewski; Maciej Tupaj; [2014]
    Nyckelord :Control Algorithm; Flexible Manufacturing System; Industrial Networks; Industrial Robot; Waterjet Machine; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

    Sammanfattning : The main goal of this work is to create a flexible manufacturing system for the waterjet cutting application. This kind of process is a high-risk activity with possible injuries if details are removed manually. To avoid this problem, a system can be fully automatized excluding presence of human interaction.

  7. 25. Streamlining tool design and manufacturing process for blancing and function test equipment to a propeller hub assembly

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik

    Författare :Jimmy Vestlund; [2014]
    Nyckelord :Modular Function Deployment; Lean; Lean Product Development; Product Architecure; Cross Functional Process Map; Value Stream; Concurrent Engineering; Product Improvement;

    Sammanfattning : Rolls-Royce AB in Kristinehamn, Sweden, part of Rolls-Royce Marine, is a leading developer and supplier of water jet and propeller based propulsion equipment. Its low volume production series and wide product variety offered to its customers along with an increasingly competitive market has entailed an increased demand on both delivery time and cost reductions.
