  1. 1. Design & Assembly of a Modular 1-Cylinder Steam Expansion Test Rig for the Evaluation of Piston Rings and Valve Mechanisms

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Pinaki Das; [2023]
    Nyckelord :Steam; Test Rig; Expander; Steam; testrigg; expander;

    Sammanfattning : The need for renewable and environmentally sustainable power generation has increased manifolds in the recent years. Extensive research has been carried out for better solutions. One such solution is steam power generation. LÄS MER

  3. 2. A final drive device for torque vectoring in small racing cars

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Sven Kalkan; [2023]
    Nyckelord :Torque vectoring; differential; formula student; racecar; racing; BorgWarner; product development; Technology and Engineering;

    Sammanfattning : The agility of the car can be improved by distributing the longitudinal tire forces unevenly between the wheels. The resulting yaw moment helps the car to steer in transient driving scenarios, like on a slalom course. The available grip in steady state cornering can also be increased along with stability.

  4. 3. Påldrivning: Jämförelse mellan luft- och vattendriven borrning : En utredning av jämförelser avseende slitage, logistik och driftkostnader

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Andreas Bengtsson; Pierre Bodin; [2022]
    Nyckelord :: percussion hammer; pilot; DTH; pile driving; wear; drill rig; casing; piston; check valve; water-handling; sedimentation; : sänkhammare; pilot; DTH; pålning; slitage; borrigg; foderrör; kolv; backventil; vattenhantering; sedimentering;

    Sammanfattning : Skanska Grundläggning in Region Special wishes to gain an increased understanding of the extent to which it differs in the wear of percussion hammers and pilot drill crowns, depending on which driving medium is used in down-the-hole drilling, as well as logistical and economic aspects depending on the chosen method. Down-the-hole drilling means that the hammer works down in the borehole and forms one of the components at the far end of the drill string together with a drill bit. LÄS MER

  5. 4. Optimal dead space in axial-type expander

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Martin Karman; [2022]
    Nyckelord :Dead space; Expander; Steam engine; Tolerance analysis; Axial-kolvmotor; Effektivitet; Expansionskammare; Kolv; Ångmotor;

    Sammanfattning : In this thesis a method for determining optimal dead space in an axial-type expander is developed. The axial-type expander in question is for use in a steam engine, a environmental friendly and fuel-agnostic alternative to the ICE-engine. LÄS MER

  7. 5. Multidisciplinary Modelling of Water Piston Oscillations in Wave Energy Converters : Assessment of Flow Resistance Through CFD Modelling with Fluid Structure Interactions

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Linnéa Tebelius; [2022]
    Nyckelord :Fluid Mechanics; Point Absorber; CFD; WEC; Waves4Power; Strömnigsmekanik; Point Absorber; CFD; WEC; Waves4Power;

    Sammanfattning : As the world’s need for electricity increases, so does its demand for sustainable energy with low to no greenhouse gas emissions. One of these renewable sources of energy is the Ocean which is one of the world’s largest and most predictable energy source, where the extraction of energy can be from waves or tidal current, with zero greenhouse gas emissions during production.
