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

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

    Author : Johan Samuelsson; [2022]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 2. Review and Design Adaptations of a SrCl2-NH3 bench-scale Thermochemical Heat Storage system

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Hjörtur Brynjarsson; [2021]
    Keywords : Thermochemical heat storage TCS ; SrCl2-NH3; system design; kinetics; absorption; desorption; octaammine; diammine; monoammine; pressure management; commissioning; Termokemisk värmelagring TCS ; SrCl2-NH3; systemdesign; kinetik; absorption; desorption; oktaammin; diammin; monoammin; tryckhantering; driftsättning;

    Abstract : Thermochemical heat storage (TCS) is a thermal energy storage (TES) technology used to store thermal energy for later use. TCS can provide heating or cooling services from intermittently available thermal energy, often low grade waste heat. READ MORE

  4. 3. Model-Predictive Control of Gas Exchange in a Gasoline Engine

    University essay from Linköpings universitet/Fordonssystem

    Author : George Jajji; [2021]
    Keywords : Control Engineering; Model Predictive Control; MPC; Gasoline Engine; Gas Exchange;

    Abstract : The process to induct air into engine cylinders, via the air inlet system and cylin-der port valves, is referred to as the "gas-exchange". Control is achieved by theturbo-charger, the intake throttle plate and the variable valve timing (VVT) sys-tem. These actuation systems traditionally use separate control with indepen-dent SISO feedback. READ MORE

  5. 4. Development of Inlet Valve in an Oil­-free Novel Steam Engine

    University essay from KTH/Maskinkonstruktion (Inst.)

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

    Abstract : 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. READ MORE

  6. 5. Modelling of a Liquid Metal Loop System : For X-ray Applications

    University essay from KTH/Hållfasthetslära

    Author : Anton Persson; [2020]
    Keywords : ;

    Abstract : A closed system of a liquid metal jet loop operating in vacuum is modelled and investigated using a commercial 1D simulation tool. Possible methods to approximate a free-falling jet in vacuum to capture the behavior of the system in 1D is investigated. READ MORE
