1. 11. Experimental Investigation of Hydrodynamic Effects on a Vibrating Kaplan Runner

   University essay from Luleå tekniska universitet/Strömningslära och experimentell mekanik

   Author : Jakob Hedlund; [2017]
   Keywords : FSI; fluid-solid interactions; Kaplan runner; hydrodynamic; added mass; added damping; vibrations;

   Abstract : An experimental investigation of a vibrating Kaplan turbine runner was performed in order to understand the hydrodynamic effects and to obtain or confirm the mass and damping coefficients used for dimensioning at the design stage. Improved design can lead to increased efficiency and lifetime of hydropower stations. READ MORE

3. 12. The oil price-macroeconomy relationship revisted

   University essay from Göteborgs universitet/Institutionen för nationalekonomi med statistik

   Author : Julius Hellström; Henrik Forsberg; [2016-07-01]
   Keywords : oil price shock; Financial stress; Asymmetric oil-macroeconomy relationship; IS LM-framework;

   Abstract : Our study aims to evaluate the Mundell-Fleming model ability to predict the effects from a oil price shock to output and interest rates by analyzing data, from the last thirty years, by using a VAR-model. Our results show an asymmetric effect between oil price and GDP growth while the oil price-interest rate relationship partly holds. READ MORE

4. 13. Numerical Investigations of a Partitioned FSI Algorithm for Tetra Pak's Filling Tube

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Leo Andersson; [2016]
   Keywords : fluid-structure interaction; FSI; added mass effect; partitioned implicit scheme; stability; Rayleigh damping; grid flux under-relaxation; Technology and Engineering;

   Abstract : 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

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

   University essay from KTH/Kraft- och värmeteknologi

   Author : Giacomo Bernardi; [2015]
   Keywords : HAWT; CFD; Aeroelasticity;

   Abstract : 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. READ MORE

6. 15. Predictability and performance of different non-linear mixed-effects models for HbA1c in patients with type 2 diabetes mellitus

   University essay from Institutionen för farmaceutisk biovetenskap; Institutionen för biologisk grundutbildning

   Author : Gustaf Wellhagen; [2014]
   Keywords : Type 2 diabetes mellitus; semi-mechanistic models; HbA1c; glucose; insulin; NONMEM;

   Abstract : To accurately predict the outcome of a late phase study, pharmacometric models can help in drug development. Making informed decision on which models to use will also facilitate drug development. This can depend on the mechanism of action for the drug as well as stability and runtime factors. READ MORE
