  1. 21. Feasibility Study of a 3D CFD Solution for FSI Investigations on NREL 5MW Wind Turbine Blade

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Giacomo Bernardi; [2015]
    Nyckelord :HAWT; CFD; Aeroelasticity;

    Sammanfattning : With the increase in length of wind turbine blades flutter is becoming a potential design constrain, hence the interest in computational tools for fluid-structure interaction studies. The general approach to this problem makes use of simplified aerodynamic computational tools. LÄS MER

  3. 22. Three-dimensional constitutive finite element modeling of the Achilles tendon

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Giacomo Longo; [2015]
    Nyckelord :Constitutive modeling; FEM; Achilles tendon; Soft tissue; Fluid behaviour; 3D geometry; Technology and Engineering;

    Sammanfattning : Tendons connect muscles to bones enabling efficient locomotion. This study focuses on the Achilles tendon, which is the strongest tendon in the body and fundamental for activities like walking, running and jumping. The Achilles tendon is the most frequently subjected tendon when it comes to injuries and ruptures. LÄS MER

  4. 23. Investigation of the Lock-in behavior of an eccentrically rotating cylinder in regard to turbomachinery application.

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Sina Samarbakhsh; [2014]
    Nyckelord :Non-synchronous vibration; Vortex-induced vibration; Oscillating cylinder; Vortex shedding; Fluid-structure interaction;

    Sammanfattning : Interaction of fluctuating vortex shedding with blade vibration can lead to a new class of aeromechanical instability referred as Non-synchronous vibrations. Investigating a well-known case that shows similar NSV features such as a circular cylinder can develop the understanding of physics behind NSV. LÄS MER

  5. 24. Influence of Fluid Structure Interaction on a Concrete Dam during Seismic Excitation : -Parametric analyses of an Arch Dam-Reservoir-Foundation system

    Master-uppsats, KTH/Betongbyggnad

    Författare :Rikard Hellgren; [2014]
    Nyckelord :seismic; fluid-structure interaction; arch dam; concrete; finite element analysis; jordbävning; fluid-struktur interaction; valvdamm; betong; finit element analys;

    Sammanfattning : The aim of this study is to investigate how Fluid-Structure interaction is included in numerical earthquake analyses of dams. The base for this project is theme A from the 12th international benchmark workshop on numerical analysis of dams, which was held in October 2013. LÄS MER

  7. 25. Testing and optimization of Unicorn Fluid-Structure Interaction solver for simulating an industrial problem

    Master-uppsats, KTH/Numerisk analys, NA

    Författare :Vu Thi Thanh Truc; [2014]
    Nyckelord :;

    Sammanfattning : In industry applications, such as power supply plants, the issue of interaction between fluid and structure is always presented. More precisely, the fluid flow affects the structure by applying force(s) on it and vice versa. As a result, the structure can move (vibrate) or deform. LÄS MER
