  2. 1. Absorbing Layers and Non-Reflecting Boundary Conditions for Wave Propagation Problems

    Author : Daniel Appelö; Prof. Gunilla Kreiss; Eliane Becache; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PML; perfectly matched layer; Numerical analysis; Numerisk analys;

    Abstract : The presence of wave motion is the defining feature in many fields of application,such as electro-magnetics, seismics, acoustics, aerodynamics,oceanography and optics. In these fields, accurate numerical simulation of wave phenomena is important for the enhanced understanding of basic phenomenon, but also in design and development of various engineering applications.

  4. 2. Modelling of Moving Contact Lines in Two-Phase Flows

    Author : Hanna Holmgren; Gunilla Kreiss; Stefan Turek; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computational fluid dynamics; Two-phase flow; Contact lines; Scientific Computing; Beräkningsvetenskap;

    Abstract : Moving contact line problems appear in many natural and industrial processes. A contact line is formed where the interface between two immiscible fluids meets a solid wall. Examples from everyday life include raindrops falling on a window and water bugs resting on water surfaces. READ MORE

  5. 3. Aspects of viscous shocks

    Author : Malin Siklosi; GUnilla Kreiss; Smadar Karni; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Numerical analysis; hyperbolic conservation laws; viscous shocks; modified equation; shock capturing; computer-assisted proofs; Numerisk analys; Numerical analysis; Numerisk analys;

    Abstract : This thesis consists of an introduction and five papers concerning different numerical and mathematical aspects of viscous shocks. Hyperbolic conservation laws are used to model wave motion and advect- ive transport in a variety of physical applications. READ MORE
