  1. 26. Approaching Large Eddy Simulation of Cavitating Flows for Marine Applications

    Författare :Niklas Wikström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VOF; OpenFOAM; CFD; LES; Navier-Stokes; incompressible free surface flow; Cavitation;

    Sammanfattning : Cavitation is a major concern in naval craft design as well as in the shipping industry. Although the nature of cavitation is not fully understood, propellerdesigns are presently improved by experimental analysis of the phenomena. LÄS MER

  3. 27. On Steady Water Waves and Their Properties

    Författare :Mats Ehrnström; Matematik (naturvetenskapliga fakulteten); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Particle trajectories; Water waves; Vorticity; Maximum principles; Elliptic equations;

    Sammanfattning : Abstract: This thesis consists of four papers related to various aspects of steady water waves. Paper I: Deep-water waves with vorticity: symmetry and rotational behaviour. We show that for steady, periodic, and rotational gravity deep-water waves, a monotone surface profile between troughs and crests implies symmetry. LÄS MER

  5. 29. Accurate quadrature and fast summation in boundary integral methods for Stokes flow

    Författare :Joar Bagge; Anna-Karin Tornberg; Katarina Gustavsson; Adrianna Gillman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Numerical Analysis; Numerisk analys;

    Sammanfattning : This thesis concerns accurate and efficient numerical methods for the simulation of fluid flow on the microscale, known as Stokes flow or creeping flow. Such flows are important, for example, in understanding the swimming of microorganisms, spreading of dust particles, as well as in developing new nano-materials, and microfluidic devices that can be used for on-the-fly analysis of blood samples, among other things.
