  2. 2. Computational Techniques for Coupled Flow-Transport Problems

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Martin Kronbichler; Gunilla Kreiss; Jean-Luc Guermond; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Finite element method; saddle point systems; two-phase flow; level set method; phase field method; stabilization; contact line dynamics; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : This thesis presents numerical techniques for solving problems of incompressible flow coupled to scalar transport equations using finite element discretizations in space. The two applications considered in this thesis are multi-phase flow, modeled by level set or phase field methods, and planetary mantle convection based on the Boussinesq approximation. READ MORE

  3. 3. Development of fine-mesh methodologies for coupled calculations in Light Water Reactors

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Klas Jareteg; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Coupled neutronics thermal-hydraulics; nuclear reactor multiphysics; multiphase flow;

    Abstract : This thesis presents fine-mesh multiphysics methodologies and algorithms for numerical predictions of the behavior of Light Water Reactor (LWR) cores. The multiphysics aspects cover the distribution of neutrons, the fluid flow of the coolant and the conjugate heat transfer between the solid fuel pins and the fluid coolant. READ MORE

  4. 4. Development of a Free Surface Capability in a RANS Solver with Coupled Equations and Overset Grids

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Michal Orych; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; free-surface; overset; RANS;

    Abstract : This thesis is a result of investigations carried out during the implementation of a free surface capturing method in a RANS solver. The work consists of two distinct parts which complement each other, and the purpose is to improve the free surface interface sharpness and to reduce numerical diffusion of the gravity waves.

  5. 5. Methods and Tools for Co-Simulation of Dynamic Systems with the Functional Mock-up Interface

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Christian Andersson; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coupled Systems; Co-Simulation; FMI; Functional Mock-up Interface; PyFMI; Assimulo; Stability; Master Algorithm;

    Abstract : Simulation of coupled dynamical systems, where the subsystems are bundled with their own internal solver, is important in industry. This is due to that in many cases, with complex systems, this is the only viable option. READ MORE
