  1. 1. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

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

    Author : Nipon Roy; [2023]
    Keywords : Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

    Abstract : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. READ MORE

  3. 2. Possibilities of Reducing Internal Scrap Rates and Increase Scrap Recyclability of Dilute Copper Alloys from Vertical Upwards Continuous Cast (VUCC) Process

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Minna Olsson; [2023]
    Keywords : metallurgy; copper; alloy; continuous casting; materials chemistry; Technology and Engineering;

    Abstract : Copper and copper alloys are important material systems for the electrification of society. The high workability of the materials makes them appropriate in numerous different applications which require highly conductive properties. READ MORE

  4. 3. Heat-pipes in electric machines : Heat management in electric traction motors

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Anton Olofsson; [2022]
    Keywords : Heat-pipe; Heat pipe; FEM; LPM; Traction motors; Induction motor; Heat management;

    Abstract : The world is continually changing towards more energy efficient alternatives and less pollution. For the traction market, electric powertrains have become the go-to method, superior to both steam and diesel-electric hybrid systems. READ MORE

  5. 4. Development of Test Rig and Experimental Evaluation of Hydrostatic Bearings for an Axial Flux Machine

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Amir Avdic; Kishore-Babu Vejendla; [2022]
    Keywords : viscous losses; hydrostatic bearing; hydrodynamics; thin oil film.; Viskösa förluster; generator; hydrostatiska lager; hydrodynamik; tunn oljefilm.;

    Abstract : A novel electric machine design, similar to an axial flux machine, incorporates hydrostatic bearings to increase efficiency and stability of said machine. In this thesis, the feasibility of a hydrostatic solution is explored and evaluated by development, manufacturing, and assembly of a test rig, as well as running experimental tests with it.

  6. 5. Statistical analysis of firefighting and damage caused by fire in mid-rise timber-framed residential buildings compared to other construction types

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Thomas Berg; [2021]
    Keywords : Statistical analysis; timber-framed; residential; firefighting; damage caused by fire; PRONTO; NFID; linear regression; summary statistics; Technology and Engineering;

    Abstract : The contribution of greenhouse gas emissions in the production of construction materials has sparked a new interest and recent changes in building regulations regarding the use of renewables like wood as the main component in load-bearing elements. Recent regulation changes focus on allowing taller timber structures which bides the question of how to adequately maintain an acceptable level of fire protection considering the characteristically flammable properties of wood-based products.
