1. 16. Automatic detection of the fuel composition in a Diesel Engine : Identifying fuel composition in the fuel system of a combustion engine and optimising for computational complexity

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Andree Hultgren; [2021]
   Nyckelord :Fuel Detection; Machine Learning; Feature Selection; Computational Complexity; Bränsledetektering; Maskininlärning; Paremeterval; Beräkningskomplexitet;

   Sammanfattning : The transportation industry is responsible for 26% of all emission of greenhouse gases in the European Union. Many steps are being taken to minimise greenhouse gas emissions. The most effective way to reduce the emission of greenhouse gases is by transitioning to biofuels. LÄS MER

3. 17. 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. 18. Framtidens bränslemix i Härnösand : en jämförelse av HEMAB:s potentiella bränslemixar

   Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Energy and Technology

   Författare :Oliver Christiansson; [2021]
   Nyckelord :HEMAB; fjärrvärme; bränslemix; biodrivmedel;

   Sammanfattning : Härnösands Energi och Miljö AB (HEMAB) provides district heating in Härnösand and is owned by Härnösand municipality. The fuel mixture of the district heating plant mainly consists of forest residuals, but also some peat. Whether peat is to be considered a fossil fuel or not is debated, however in most cases it is regarded as a fossil fuel. LÄS MER

5. 19. Aerothermal and Kinetic Modelling of a Gas Turbine Dry Low Emission Combustion System

   Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

   Författare :David Håkansson; [2021]
   Nyckelord :Gas turbine; combustion; one-dimensional combustion simulation; network model; general network model; NOx emissions; hydrogen; Gasturbin; förbränning; endimensionell förbränningssimulering; nätverksmodell; generell nätverksmodell; NOx-utsläpp; väte;

   Sammanfattning : Growing environmental concerns are causing a large transformation within the energy industry. Within the gas turbine industry, there is a large drive to develop improved modern dry-low emission combustion systems. The aim is to enable gas turbines to run on green fuels like hydrogen, while still keeping emission as NOx down. LÄS MER

7. 20. Creating a Dynamic Model of a Gas Turbine in the MVEM Framework Using an Ellipse Compressor Model

   Master-uppsats, Linköpings universitet/Fordonssystem

   Författare :Edvin Hansson; [2020]
   Nyckelord :Gas turbine; Modeling; control;

   Sammanfattning : The legislations on greenhouse gas emissions are getting tougher and tougher every year. This drives the demand for energy efficient gas turbines with as low emissions as possible. This poses the challenge to manufacturers of constructing gas turbines with lessened environmental impact, but with maintained performance. LÄS MER
