  1. 1. Do viscous flows slip?

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Björn Sjösvärd; [2023-12-21]
    Keywords : Mathematics; partial differential equations; multivectors; Hodge de-compositions; the Stokes equation; Hodge boun;

    Abstract : In this thesis, the Stokes equation is discussed and solved under different boundary conditions. The Stokes equation governs the flow of viscous liquids, for example honey or syrup. The first chapters in the thesis provides an introduction to multivector algebra and analysis, with the aim of presenting the concept of Hodge decompositions. READ MORE

  3. 2. Transients and Coil Displacement in Accelerator Magnets

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Marcus Wallin; [2019]
    Keywords : Accelerator Magnets; Nb3Sn; Displacement; Slip-Stick; ROXIE; CERN; Transients; Coil;

    Abstract : For a long time voltage spikes has been seen in measurement data from accelerator magnets during current ramps. These has been believed to be caused by movements, but has never before been studied in depth. READ MORE

  4. 3. Bronze-Steel Friction Characteristics under the Lubrication of Modified Water/Glycerol Mixtures

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Karim Hamouda; [2017]
    Keywords : Glycerol; glycerol additives; stick-slip; shudder; friction modifiers;

    Abstract : Increasing environmental awareness has driven a lot of research to look into various environmentally friendly lubricants which can replace more conventional mineral oil based lubricants. This is true in particular for marine and hydropower applications where the risk of lubricant leakage can be damaging to the local environment. READ MORE

  5. 4. Screaming screw tightenings

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Jacob Andersson; Fredrik Danielsson; Wilhelm Löwen; [2017]
    Keywords : scream; screw joints; stick-slip; skrik; skruvförband; stick-slip;

    Abstract : This paper is a bachelor thesis in machine design where screaming screw tightenings are discussed. The research was initiated with a preliminary study in screw mechanics and the tightening process, as well as the stick-slip phenomenon. READ MORE

  6. 5. An investigation of friction graphs ranking ability regarding the galling phenomenon in dry SOFS contact : (Adhesive material transfere and friction)

    University essay from Karlstads universitet/Fakulteten för teknik- och naturvetenskap

    Author : Harald Wallin; [2008]
    Keywords : galling; friction; adhesive contact; mild adhesive; severe adhesive; abrasive; flattening; SOFS; TNO; slider on flat surface; tribology; dry; lubricated; frictional heating; acceleration; plastic zone; contact pressure; pressure; phase transformation; morphology; seizure; scoring; scuffing; cohesive forces; classification; characteristic patterns; lump; sheet damage; på kletning; friction; kontakt tryck; värme; plogning;

    Abstract : The main purpose of this project is to investigate different tool steels in terms of their ability to withstand material transfer buildup, so-called galling, occurring in SMF (sheet metal forming) operations. The ability to withstand galling is vital to optimize cost-effectiveness and increase the work tool’s effective operational time. READ MORE
