  4. 23. Dimensioning of a cutter wheel bearings

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Kebin Xie; [2020]
    Keywords : cutter wheel; bearing; wear; scuffing; Archard equation; lubrication number; Reynold equation; Hertzian contact theory; impact load factor; FE model; Ansys; contact pressure on bearing;

    Abstract : Mobile Miner 40V is a machine used for rock excavation and developed by Epiroc. This machine is equipped with a large cutter wheel to perform the excavation. After a test run, some surfaces associated with bearings within the cutter wheel were found to be damaged due to scuffing - severe sliding wear. READ MORE

  5. 24. Evaluation of drag estimation methods for ship hulls

    University essay from KTH/Mekanik

    Author : Hampus Tober; [2020]
    Keywords : ;

    Abstract : This study aims to evaluate to which degree CFD can complement traditional towing-tank experiments, and to develop a computationally cheap and robust methodology for these type of simulations. Two radically different surface ship hulls were chosen for the trials: a capesize bulk carrier and a fast displacement hull. READ MORE

  6. 25. Influence of Reynolds Number and Heat Flux when Cooling an Array of Cylinders

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Erik Fagerström; [2020]
    Keywords : Reynolds Number; Heat Flux; Porous Media; Cooling;

    Abstract : When batteries are used, it is of interest to know how high the temperature will become and if the cooling is efficient enough. In this thesis project, the geometry used are batteries placed in an array shape, inside a box. This gives the possibility of assuming porosity conditions when looking at the box from the outside.
