  1. 1. Material analysis for a rotating inlet valve : Sliding contact in an oil-free super-critical steam environment

    Uppsats för yrkesexamina på avancerad nivå, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Johan Samuelsson; [2022]
    Nyckelord :Mechanical carbon; graphite; carbon graphite; zirconia; steam engine; steam; tribology; friction; wear; stellite; nitronic 60; antimony; carbon; Ni-resist cast iron; waste heat recovery; rotating inlet valve; valve; Mekaniskt kol; gafit; ångmotor; ånga; tribologi; friktion; nötning; gjutjärn; roterande inloppsventil; ventil;

    Sammanfattning : In this thesis, the aim is to study possible tribo-materials for a rotating inlet valve and to find a suitable material combination for the contact. The valve is part of a modern oil-free and high temperature steam engine. Systematic material selection together with tribological tests and wear analyses are performed. LÄS MER

  3. 2. Development of Inlet Valve in an Oil­-free Novel Steam Engine

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Gautam Rajeev; Dinesh Thirunavukkarasu; [2021]
    Nyckelord :Steam engine; rotational valve; actuator mechanism; sealing; Ångmotor; rotationsventil; ställdon; tätning;

    Sammanfattning : A novel compact steam engine design could be used to replace current combustion engines in the rapidly changing world of renewable energy. Especially with the increased research into alternative fuels such as hydrogen fuel cells and methane, which would vastly improve the efficiency of a steam engine. LÄS MER

  4. 3. Techniques to inject pulsating momentum

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Strömningslära och experimentell mekanik

    Författare :Jelle Kranenbarg; [2020]
    Nyckelord :Hydro power; Rotating Vortex Rope; Flow control; Fluidic actuator; Synthetic jet actuator; Piston actuator; CFD;

    Sammanfattning : Hydro power plants are an essential part of the infrastructure in Sweden as they stand for a large amount of the produced electricity and are used to regulate supply and demand on the electricity grid. Other renewable energy sources, such as wind and solar power, have become more popular as they contribute to a fossil free society. LÄS MER

  5. 4. Flödesanalys av roterande ventil i ångmotor

    M1-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Victor Andersson; [2018]
    Nyckelord :rotary valve; cfd; steam engine; steam; pressurized steam; roterande ventil; flödesanalys; cfd; ångmotor; trycksatt ånga;

    Sammanfattning : This report is a bachelor thesis at Karlstad University in collaboration with Invencon AB and Ranotor AB. The goal was to analyze a rotating valve leading water vapor through an inlet and five outlets. LÄS MER

  7. 5. An Experimental Analysis of Valve Plate Control : a New Approach to Displacement Control for Hydraulic Piston Machines

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Kärnell Samuel; [2017]
    Nyckelord :;

    Sammanfattning : Displacement control of a pump means controlling the amount of fluid that is pumped per rotation. This is used to increase the efficiency or controlling the flow in a system and currently there is almost exclusively one type of displacement control available for piston machines on the market.
