  1. 1. Friction and wear study of lean powder metallurgy steel in a lubricated sliding contact

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Caroline Lejonklo; [2019]
    Keywords : Lean steel; Powder metallurgy PM ; Powder metallurgy steel PM steel ; Friction; Wear; Sliding contact; Lubricated; Porosity; Tribology; Adhesive wear; Abrasive wear; Gear; Gear tooth; Particles; Polyalphaolefin 8 PAO 8 ; Contact pressure; Density; Light optical microscopy LOM ; Scanning electron microscopy SEM ; Energy-dispersive X-ray spectroscopy EDS ; Vertical svanning interferometry VSI ; Pin on disc; Pin-on-disc;

    Abstract : A fairly new technology used to produce metallic components is powder metallurgy (PM). Among the advantages with this technique are decreased cost of production for complex-shaped parts, new alloys are made possible, reduced end processing, less material loss, and vibrational damping effects.

  2. 2. Significance of Fracture Patterns in a Rock Mass during Excavation by Blasting in Bandhagen, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Mattias Ryttberg; [2015]
    Keywords : Fracture sets; rock excavation; rock wall; instability; Spricksystem; utschaktning; bergvägg; instabilitet;

    Abstract : When excavating a rock wall by blasting, pre-existing structures in the rock has a strong impact on the stability of the wall. For excavation in Bandhagen in Stockholm, the nature and orientation of the pre-existing geological features, namely fractures, were not taken into consideration before excavation begun. READ MORE

  3. 3. Simulating propeller and Propeller-Hull Interaction in OpenFOAM

    University essay from KTH/Marina system

    Author : Reza Mehdipour; [2014]
    Keywords : CFD; OpenFOAM; AMI; MRF; Open Water Characteristics; Self-Propelled Ship; Scalability; Parallel Computing;

    Abstract : This is a master’s thesis performed at the Department of Shipping and Marine Technology research group in Hydrodynamics at Chalmers University of Technology and is written for the Center for Naval Architecture at the Royal Institute of Technology, KTH.In order to meet increased requirements on efficient ship propulsions with low noise level, it is important to consider the complete system with both the hull and the propeller in the simulation.

  4. 4. Numerical simulations of the flow in the Francis-99 turbine

    University essay from Chalmers tekniska högskola/Institutionen för tillämpad mekanik

    Author : Lucien Stoessel; [2014]
    Keywords : Hydropower; Francis Turbine; OpenFOAM; Mixing Plane; Sliding Grid; Turbulence Modelling; EARSM; Runner Oscillations;

    Abstract : In a modern electricity generation framework, hydroturbines are used to stabilise the grid and equilibrate supply variations of other renewable energy sources and are therefore often operated at off-design conditions. In this thesis, the scale model of a high-head Francis turbine is investigated at part load, best efficiency point and high load using a finite volume method in OpenFOAM. READ MORE
