1. 1. Structural responses due to underwater detonations : Validation of explosion modelling methods using LS-DYNA

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Gustav Blomgren; Ebba Carlsson; [2023]
   Keywords : Underwater explosion; UNDEX; detonation; fluid structure interaction; FSI; SSA; S-ALE; shock-wave; explosive; PETN; explosive modelling; Sub-Sea Analysis; Structured ALE; Arbitrary Lagrangian Euler; Multi Material Arbitrary Lagrangian Euler; MMALE; LS-DYNA;

   Abstract : Modelling the full event of an underwater explosion (UNDEX) is complex and requires advanced modelling methods in order to achieve accurate responses. The process of an UNDEX includes a series of events that has to be considered. READ MORE

3. 2. CFD Analysis of the Flow Around a Paraglider Wing

   University essay from KTH/Teknisk mekanik

   Author : Caterina Gennari; [2023]
   Keywords : Paraglider Wing; CFD; RANS; DES; Aerodynamics; Aerodynamic Hysteresis; FSI; Deformable Structure; Membrane; Shell Elements;

   Abstract : In this study, the characteristics of the flow around a paraglider wing were investigated through the use of Computational Fluid Dynamics (CFD) simulations by solving both Reynolds Averaged Navier-Stokes equations and Delayed Detached Eddy Simulations were employed. This allowed the observation of how the unique shape of the canopy of a paraglider can influence the behaviour of the flow and how aerodynamic hysteresis can manifest on this sort of wing. READ MORE

4. 3. The Investigation and Modeling of the interaction between Paperboard Clippings in a Pipe Flow

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Lea Christierson; [2021]
   Keywords : Fluid-structure interaction; paperboard material modeling; transient pipe flow; overset mesh; image analysis; Technology and Engineering;

   Abstract : In the manufacturing process of Tetra Pak packages, holes are cut out of the paperboard for straws and caps. The left-over paperboard clippings, called confetti, need to be evacu- ated from the machine. However, this evacuation process has proven to cause problems due to jams arising as the confetti get stuck in joints and along the pipe walls. READ MORE

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

   University essay from KTH/Marina system

   Author : David Ahlsén; [2018]
   Keywords : ;

   Abstract : 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. READ MORE

6. 5. Fluid-Structure Interaction; Numerical Modelling andExperimental Comparison

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

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

   Abstract : 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. READ MORE
