  1. 1. Construction and Evaluation of a Numerical Model for Heat Transfer in a Ladle During Pre-heating : A Finite Volume Approach to the Diffusion Equation using Julia

    University essay from KTH/Materialvetenskap

    Author : Gustaf Bjurstam; [2023]
    Keywords : Finite Volume Method; FVM; Diffusion equation; Ladle; Pre-heating; Baking; Heat equation; Heat transfer; Finita Volymmetoden; FVM; Diffusionsekvationen; Skänk; Förvärmning; Värmeledningsekvationen; Värmeledning;

    Abstract : Heat transfer is key to understanding many processes in engineering. At a steel mill heat transfer is absolutely crucial to understanding most of the processes. One such a process is the pre-heating of a freshly relined ladle. READ MORE

  2. 2. Thermal Initiation of Energetic Materials Caused by Hot Fragments

    University essay from KTH/Matematik (Avd.)

    Author : Sirak Ghebreamlak; [2022]
    Keywords : Applied mathematics; computational mathematics; heat equation; thermal initiation; chemical kinetics; energetic materials; Tillämpad matematik; beräkningsteknik; värmeledningsekvationen; termisk initiering; kinetik; energetiska material;

    Abstract : The cause of unintentional initiations of energetic materials is an important area of study due to the risks that comes with storing energetic materials such as high explosives. The current models used to simulate the process of heating energetic materials by a hot metal fragment do not give reliable predictions. READ MORE

  3. 3. Physics-Informed Machine Learning in Power Transformer Dynamic Thermal Modelling

    University essay from KTH/Matematisk statistik

    Author : Federica Bragone; [2021]
    Keywords : ANN; PINN; PDE; FVM; Transformer; Thermal modelling; ANN; PINN; PDE; FVM; Transformatorer; Termisk modellering;

    Abstract : Artificial neural networks (ANNs) are commonly considered as "black boxes": they can approximate any function without giving any interpretation. Novel research has observed that the laws of physics, which govern everything around us, can supplement the implementation of a neural network. READ MORE

  4. 4. Pricing Financial Derivatives with the FiniteDifference Method

    University essay from KTH/Matematisk statistik

    Abstract : In this thesis, important theories in financial mathematics will be explained and derived. These theories will later be used to value financial derivatives. READ MORE

  5. 5. Inverse Parameter Estimation using Hamilton-Jacobi Equations

    University essay from KTH/Numerisk analys, NA

    Author : Mikael Helin; [2013]
    Keywords : Hamilton-Jacobi equation. Optimal control. Euler method.; Hamilton-Jacobi ekvationer. Optimal styrning. Eulers stegmetoder;

    Abstract : Inthis degree project, a solution on a coarse grid is recovered by fitting apartial differential equation to a few known data points. The PDE to consideris the heat equation and the Dupire’s equation with their synthetic data,including synthetic data from the Black-Scholes formula. READ MORE
