  1. 1. Compressor Surge: Simulation, Modeling and Analysis

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Robin Massiquet; [2022]
    Keywords : Turbo compressor; Surge; Simulation; Modelling;

    Abstract : The master thesis subject takes place in the automotive industry and specifically in the internal combustion engine area. The need of improving the efficiency of the engines leads to develop new technologies like turbo compressors. Some of the challenges to overcome are high rotational speed difficulties or extreme load and fatigue in the rotors. READ MORE

  3. 2. 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

  4. 3. Estimation of Air Mass Flow in Engines with Variable Valve Timing

    University essay from Linköpings universitet/Reglerteknik

    Author : Elina Fantenberg; [2018]
    Keywords : Diesel Engine; Variable Valve Timing; Air Mass Flow;

    Abstract : To control the combustion in an engine, an accurate estimation of the air mass flow is required. Due to strict emission legislation and high demands on fuel consumption from customers, a technology called variable valve timing is investigated. READ MORE

  5. 4. Design of a rotary valve for pressurised steam

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Talent Nyawo; [2016]
    Keywords : rotary valve; uniflow engine; gas-tight sealing; variable cut-off time; high-pressure-high-temperature; roterande ventil; uniflow motor; gastät försegling; rörlig bryttidpunkt; hög-tryck-hög-temperatur;

    Abstract : Denna rapport är gjord på ett examensarbete som var utfört på uppdrag av det svenska företaget Ranotor AB. Syftet var att utveckla en konceptuell lösning för en rotationsventil som skall fungera i en miljö med hög temperatur och högt tryck. Ventilen skall arbeta under höga rotationshastigheter, vilket kräver korta öppettider. READ MORE
