  1. 1. Fluid/Material Coupled Numerical Analysis of Single Bubble Collapse Near a Pit on a Wall

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Daiki Makii; [2020]
    Nyckelord :Bubble Dynamics; Cavitation Erosion; Numerical Analysis; Fluid Material Coupled Numerical Method; Homogeneous Model; Elastic Body Material; Erosion Pit;

    Sammanfattning : In order to elucidate the progression mechanism of cavitation erosion, the behaviors of a single cavitation bubble collapse near a pit on a wall and both the resulting pressure wave in fluid and stress wave in material are investigated in detail. To find out the mechanism of cavitation erosion, many experimental studies on the bubble collapse behavior near a flat rigid wall and the resulting material damage have been conducted so far.

  3. 2. A High Order Finite Difference Method for Simulating Earthquake Sequences in a Poroelastic Medium

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Kim Torberntsson; Vidar Stiernström; [2016]
    Nyckelord :numerical analysis; numerical methods; numerical modeling; SBP-SAT; finite differences; high performance computing; geophysics; geomechanics; poroelasticity; fault mechanics; induced seismicity;

    Sammanfattning : Induced seismicity (earthquakes caused by injection or extraction of fluids in Earth's subsurface) is a major, new hazard in the United States, the Netherlands, and other countries, with vast economic consequences if not properly managed. Addressing this problem requires development of predictive simulations of how fluid-saturated solids containing frictional faults respond to fluid injection/extraction. LÄS MER

  4. 3. Modeling and Simulation of Elastic Rods with Intrinsic Curvature and Twist Immersed in Fluid

    Master-uppsats, KTH/Numerisk analys, NA

    Författare :Babak Maboudi Afkham; [2014]
    Nyckelord :;

    Sammanfattning : Understanding the dynamics of thin elastic rods that are immersed in fluid is fundamental in explaining many problems that arise in biology, physics and engineering. Solving the coupled system of rod-fluid in 3D is usually very costly, however in case of low Reynolds number, the three-dimensional problem can be reduced a one-dimensional problem on the centerline of the rod.
