  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

  3. 2. 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. 3. Model of Thermal EHL Based on Navier-Stokes Equations : Effects of Asperities and Extreme Loads

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Marko Tošić; [2019]
    Keywords : ;

    Abstract : A common approach in numerical studies of elastohydrodynamic lubrication (EHL) is based on solving the Reynolds equation that governs pressure distribution in thin lubricant films. The Reynolds equation is derived from the Navier-Stokes equations by taking assumptions that are considered valid when the thickness of the lubricant film is much smaller than its length. READ MORE

  5. 4. Modelling of shell and tube heat exchangers

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : John Hellborg; [2017]
    Keywords : Technology and Engineering;

    Abstract : In this master thesis Modelica models for shell and tube heat exchangers was developed. The modelling focused on two configurations specifically; the TEMA E shell and tube heat exchanger with single-phase flow on the shell side and the TEMA G shell and tube heat exchanger with condensation on the shell side.
