  1. 6. Aerothermal and Kinetic Modelling of a Gas Turbine Dry Low Emission Combustion System

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : David Håkansson; [2021]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 7. Fundamental combustion properties of alternative fuels for energy transition

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Yijing Mao; [2020]
    Keywords : Physics and Astronomy;

    Abstract : Validation and improvement of chemical kinetic modelling require accurate experimental data. The over goal of the present work is to obtain accurate data by using techniques that have been previously implemented in common flames, e.g. READ MORE

  4. 8. Hydrus-1D as a tool to understand contamination of an aquifer: A case study in the Central Valley of Cochabamba

    University essay from Lunds universitet/Teknisk geologi

    Author : Theo Nyberg; [2019]
    Keywords : Technology and Engineering;

    Abstract : In water resource management, it is of importance to be able to predict how different activities might contaminate aquifers. For this kind of application, numerical modelling of water and solute transport can be a useful tool. READ MORE

  5. 9. Modelling the Shuttle Movement of a Seismic Airgun

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Ludvig Lindeberg; [2019]
    Keywords : seismic airgun; euler equations; finite difference; numerical analysis;

    Abstract : A provably stable and high-order accurate semi-discrete finite difference scheme modeling the shuttle movement of a seismic airgun is derived using the SBP-SAT method. The one dimensional airgun model studied consists of two pressurized compartments separated by a moving shuttle. READ MORE

  6. 10. Simulation of Leachate Generation from a Waste Rock Dump in Kiruna Using HYDRUS-1D

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Aryani Atmosudirdjo; [2019]
    Keywords : Hydrus-1D; matrix flow; leachate; unsaturated flow; waste rock dump;

    Abstract : The percolation of water through waste rock dumps at mine sites can lead to the production of a leachate with high concentrations of dissolved metals, sulfate and nitrogen compounds. It is important to understand how water flows in waste rock dumps in order to predict the environmental impact of this leachate on recipients. READ MORE
