  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. A Cut Finite Element Method for Partial Differential Equations on Evolving Surfaces

    University essay from KTH/Numerisk analys, NA

    Author : Johan Wärnegård; [2016]
    Keywords : ;

    Abstract : This thesis deals with cut finite element methods (CutFEM) for solving partial differential equations (PDEs) on evolving interfaces. Such PDEs arise for example in the study of insoluble surfactants in multiphase flow. In CutFEM, the interface is embedded in a larger mesh which need not respect the geometry of the interface.

  4. 3. Analytical model of mass transfer through supported liquid membranes

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Jonas Lantto; [2015]
    Keywords : supported liquid membranes; lanthanide extraction; analytical solution; boundary layer resistance; coupled counter-transport; Immobiliserade vätskemembran; lantanidextraktion; analytisk lösning; gränsskiktsmotstånd; kopplad mot-transport;

    Abstract : This report details the development and validation of a model for the simulation of supported liquid membrane processes, as applied to the extraction of lanthanides. Supported liquid membranes are systems where two phases, usually aqueous, are separated by a third phase, typically organic, which acts as a membrane, in order to separate solutes from one phase to the other.
