  2. 1. Numerical Study of Fluid-Structure Interaction with Application to Oscillating Cylinders

    Author : Mikhail Lazarkov; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lock-in.; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; synchronization; flow-induced vibration; LES; Volume of Solid method; Virtual Boundary method; vortex-shedding; confined cylinder; Fluid-structure interaction; wake;

    Abstract : The problem of fluid-structure interaction, occurring in many industrial and engineering applications, are of great importance, since interaction of a flow and a structure in it can lead to serious damages of the structure. The fluid-structure interaction gives rise to a variety of different physical phenomena such as flow-induced vibration, noise generation, etc. READ MORE

  4. 2. Sound Generation and Propagation in the Human Upper Airways

    Author : Lukas Schickhofer; Mihai Mihaescu; Anders Dahlkild; Mats Karlsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

    Abstract : The human upper airways embrace the source of phonation and affect the modulation of the voice, which is of vital importance for communication. Moreover, unwanted sounds may be generated in the upper airways due to elastic, collapsible parts that are susceptible to flow-induced vibration and resonance. READ MORE

  5. 3. Sensitivity of Aeroelastic Properties of an Oscillating LPT Cascade

    Author : Nenad Glodic; Damian Vogt; Matthew Montgomery; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flutter; aeroelastic response; combined modes; bending-torsion flutter; mode superposition; aerodynamic asymmetries; ROM; probabilistic analysis;

    Abstract : Modern turbomachinery design is characterized by a tendency towards thinner, lighter and highly loaded blades, which in turn gives rise to increased sensitivity to flow induced vibration such as flutter. Flutter is a self-excited and self-sustained instability phenomenon that may lead to structural failure due to High Cycle Fatigue (HCF) or material overload. READ MORE
