1. Numerical Investigations of a Partitioned FSI Algorithm for Tetra Pak's Filling Tube
University essay from Lunds universitet/Institutionen för energivetenskaperAbstract : Numerical simulations of fluid-structure interaction of a water-filled tube with a free surface are conducted using an implicit partitioned coupling scheme. Abaqus and STAR-CCM+ are used for the solid- and fluid domains respectively. This application has stability issues, with the most severe turning out to be the added mass effect. READ MORE

2. Influence of Fluid Structure Interaction on a Concrete Dam during Seismic Excitation : -Parametric analyses of an Arch Dam-Reservoir-Foundation system
University essay from KTH/BetongbyggnadAbstract : 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. READ MORE

3. Numerical simulations of energy absorbing boundaries for elastic wave propagation in thick concrete structures subjected to impact loading
University essay from Institutionen för fysikAbstract : As many of the world’s nuclear power plants are near the end of their supposed life span a need arise to assess the components crucial to the safety of these plants. One of these crucial components is the concrete reactor confinement; to assess its condition, non-destructive testing (NDT) is an attractive method. READ MORE

4. Determining the pressure distribution on submerged 2D bodies using dissipative potential flow.
University essay from KTH/Marina systemAbstract : Globalization is reaching the furthest corners of the world and with globalizations comes a rising demand on transportation. In shipping; a significant cost both to the ship owners and the environment are the fossil fuels used for propulsion, even a small reduction in the wave resistance can bring considerable reductions both in operating costs and emissions for such ships.

5. Influence of Mode Dependent Rayleigh Damping on Transient Stress Response
University essay from Blekinge Tekniska Högskola/Avdelningen för maskinteknikAbstract : Main task of thesis is to study the effect of Mode dependent Rayleigh damping on System response. Damping ratio for the structure is not constant for all modes and it varies mode wise. In present task different damping models are defined and used to obtain responses for transient system. READ MORE
