  1. 1. Cut Finite Element Methods on Overlapping Meshes: Analysis and Applications

    Författare :Carl Lundholm; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; parabolic problem; multi-objective optimization; multi-mesh; energy analysis; CutFEM; augmented reality; overlapping meshes; moving meshes;

    Sammanfattning : This thesis deals with both analysis and applications of cut finite element methods (CutFEMs) on overlapping meshes. By overlapping meshes we mean a mesh hierarchy with a background mesh at the bottom and one or more overlapping meshes that are stacked on top of it. LÄS MER

  3. 2. Robust intersection of hexahedral meshes and triangle meshes with applications in finite volume methods

    Författare :Frida Svelander; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; triangle-hex intersection; overlapping triangles; degenerate mesh; volume fraction; area fraction; cut cell; conjugated heat transfer.; triangle-hex intersection;

    Sammanfattning : The topic of this thesis is the intersection of a structured hexahedral grid and one or more triangle meshes. The interest in the problem has arisen in connection with a finite volume method for simulation of conjugated heat transfer. LÄS MER

  4. 3. Applications of Finite Element Simulation and Mixed Reality in Architecture and Built Environment

    Författare :Carl Lundholm; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; augmented reality; FEniCS; multimesh; CutFEM; multi-objective optimization; mixed reality; HoloLens; virtual reality; view computation; finite element method;

    Sammanfattning : This thesis presents applications in architecture and built environment that are based on the finite element method and mixed reality. The work consists of two main components: two projects presented in three papers. The first project (presented in Paper I) concerns an application in urban design, thus built environment on a larger scale. LÄS MER

  5. 4. Advanced Optical Diagnostics in Particle Combustion for Biomass and Metal as Alternative Fuels

    Författare :Shen Li; Förbränningsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical diagnostics; Quantitative measurement; Iron powder; Biomass; High-speed imaging; Digital holography; 3D reconstruction; SEM; Fysicumarkivet A:2022:Li;

    Sammanfattning : The energy sector is in urgent need for carbon-free strategies considering environmental pollutions and climate change impact. Two kinds of solid fuels, biomass and metal particles have been studied in this thesis aiming at CO2 emission reduction or zero carbon emission. LÄS MER
