1. 11. Comparison of electricity production between semi-submersible and spar-buoy floating offshore wind turbines

   Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Nermina Saracevic; [2018]
   Nyckelord :floating offshore wind turbine; semi-submersible; spar-buoy; six degrees of freedom; platform-rotor interaction; ASHES;

   Sammanfattning : The paper compares electricity production between the semi-submersible and the spar-buoy floating wind turbine systems under normal, stochastic and extreme wind conditions at Utsira Nord site located on the Norwegian continental shelf in the North Sea. The analysis of complex behavior of the floating wind turbine system and the fluid-structure interaction is performed in aero-servo-hydro-elastic code ASHES. LÄS MER

3. 12. A Study of a Volvo CE Articulated Hauler’s Hydraulic Tank : Validation of a Finite-Element Model Taking the Fluid-Structure Interaction into Account

   Magister-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

   Författare :Miroslav Janousek; Thibault Burnotte; [2018]
   Nyckelord :Finite-Element Analysis; Fluid-Structure Interaction; V ibrations; Hydraulic Tank; ANSYS; ANSA; META; Matlab; Volvo;

   Sammanfattning : This scientific work is dedicated to the study of the impact of vibrations on the Volvo A60 articulated hauler’s hydraulic tank taking fluid-structure interaction into account. In this work, a theoretical background is presented in order to give the reader a basic awareness of the given problem together with a detailed description of the methods used during the examination of the above mentioned hydraulic tank.

4. 13. Analytic, Simulation and Experimental Analysis of Fluid-Pipe Systems

   Master-uppsats, KTH/MWL Marcus Wallenberg Laboratoriet

   Författare :Siddharth Venkataraman; [2018]
   Nyckelord :fluid-structure interaction; modal interaction model; viscosity;

   Sammanfattning : Inviscid fluid inside thin pipe system is first analytically solved for eigenfrequencies and eigenmodes using Modal Interaction Model method with fluid-structure interaction condition at boundary. Shear-diaphragm boundary condition is used for comparing and validating Analytic results with Simulation using COMSOL Multiphysics. LÄS MER

5. 14. Experimental and numerical fluid-structure interaction analysis of a suspended rod subjected to forced vibrations

   Master-uppsats, KTH/Marina system

   Författare :David Ahlsén; [2018]
   Nyckelord :;

   Sammanfattning : This study is evaluating Solid-Acoustic Finite Element modelling as a method for calculating structural vibration response in water. When designing for example vehicles, it is important to avoid vibrational resonance in any part of the structure, as this causes additional noise and reduced lifespan. LÄS MER

7. 15. Fluid-Structure Interaction; Numerical Modelling andExperimental Comparison

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Författare :Johan Lindgren; Hannes Karlsson; [2017]
   Nyckelord :Fluid-Structure Interaction FSI LS-DYNA mat_acoustic model; Technology and Engineering;

   Sammanfattning : The purpose of this thesis is to investigate the effects of fluid-structure interaction on a submerged oscillating structure. It is to be determined whether it is possible to model such effects with acoustic fluid elements in LS-DYNA using Mat\_Acoustic. LÄS MER
