  1. 1. 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

  2. 2. 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

  3. 3. 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

  4. 4. 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

  5. 5. Solution of the Stefan problem with general time-dependent boundary conditions using a random walk method

    University essay from

    Author : Daniel Stoor; [2019]
    Keywords : Stefan problem; random walk method; moving boundary; heat transfer;

    Abstract : This work deals with the one-dimensional Stefan problem with a general time- dependent boundary condition at the fixed boundary. The solution will be obtained using a discrete random walk method and the results will be compared qualitatively with analytical- and finite difference method solutions. READ MORE
