  1. 1. SUSTAINABLE LUBRICATION FOR FUTURE TRANSMISSIONS : Micropitting performance of Glycerol-based lubricants

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

    Author : Zapata Tamayo Juan Guillermo; [2021]
    Keywords : micropitting; mild sliding wear; surface coating; diamond-like carbon DLC; glycerol-based lubrication; green lubricant; rolling contact fatigue; rolling-sliding;

    Abstract : Achieving sustainable lubrication by using environmentally friendly formulated lubricants has became an essential component of the transition process from fossil-powered vehicles to electrified transportation. Mixtures, or aqueous solutions of molecules such as polyhydroxy alcohols, and glycols usually known as green lubricants make it possible to achieve low friction coefficients under different lubrication conditions, which constitutes a potential alternative to improve the tribological performance of moving parts in automotive systems, at the same time that the environmental requirements are satisfied.

  3. 2. Hardware-In-the-Loop simulation of a small scale prototype of a Wave Energy Converter

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Anton Magnusson; [2020]
    Keywords : Hydrodynamics; Hardware-In-the-Loop; WEC-Sim; Wave Energy Converter; NEMOH; Hydrodynamik; Hardware-In-the-Loop; WEC-Sim; vågenergikonverterare; NEMOH;

    Abstract : Renewable energy sources are a hot topic, both when it comes to climate change and the constant increase in demand of electricity due to population growth and a more electrified society. One such energy source is wave energy - an energy source with great potential but still relatively new with the need for further development. READ MORE

  4. 3. Nutrients spreading with cloudburst modeling

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Nikita Smiyanov; [2020]
    Keywords : MIKE21; 2D-modeling; nutrients; phosphorus; nitrogen; cloudburst; land-use; MIKE21; 2D-modellering; närsalter; fosfor; kväve; skyfall; markanvändning;

    Abstract : Climate change and environmental disasters are strongly dependent. Humanity is facing considerable changes in environmental adaptions and remediation of contaminated sites. Water is a valuable resource that should be protected and prevented from hazardous influences. READ MORE

  5. 4. Offshore Floating Platforms : Analysis of a solution for motion mitigation

    University essay from KTH/Bro- och stålbyggnad

    Author : Alberto Rodriguez Marijuan; [2017]
    Keywords : Offshore Wind; floating platform; wave tank test; hydrodynamic pressure; structural; hydrodynamic load; heave plate.;

    Abstract : Recent events regarding energy policies throughout the globe and advances in technology are making offshore wind farms become a reality. Most offshore wind farms are still, however, built close to land masses, and need to be rigidly attached to the seabed in one way or another. READ MORE

  6. 5. New materials in sliding bearings

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Johan Salomon; [2015]
    Keywords : Sliding bearing; wear; start-stop; hydrodynamic lubrication; Glidlager; nötning; start stopp; fullfilmssmörjning;

    Abstract : Increasing demands for lower emissions from heavy trucks and buses creates new demands on the components in the engine. One such component is the journal bearing which is used at many positions in the engine. Implementing a start-stop system in a truck engine leads to that the crankshaft journal bearing gets worn out too quickly. READ MORE
