1. 1. Propulsion modelling of a generic submarine propeller

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Gustav Boman; [2023]
   Keywords : OpenFOAM; CFD; actuator line model; rotor disk; actuator disk; INSEAN E1619; propeller;

   Abstract : Self propulsion modelling is important in order to accurately simulate ships and submarinesusing Computational Fluid Dynamics (CFD). However, fully resolved simulations of hull andpropeller geometries are computationally heavy and time consuming. As such there is a greatinterest in lower order CFD models of propellers. READ MORE

3. 2. Improving the experimental setup for ultrasound-optical tomography imaging

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Ibtisam Dahir Ahmed; [2023]
   Keywords : Ultrasound-optical tomography UOT ; thulium-doped lithium niobate;

   Abstract : According to Bröstcancer förbundet, mammography is not efficient at detecting tumors in dense breast tissue or diagnosing breast cancer at its early stages. Ultrasound-optical tomography (UOT) is an imaging technique in development and has the potential for deep-tissue imaging. READ MORE

4. 3. A simplified vortex method for wind turbine simulation

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : Sandro Malusa; [2019]
   Keywords : Wind turbine; Vortex model; Numerical wake model; Vortex sheet; Vortex filament; Tjaereborg; Biot-Savart law; Iterative method;

   Abstract : A new vortex model for wind turbines was developed in order to evaluate the loads at the blades and other important characteristics of interest for the wind industry such as power and thrust coefficients. Nowadays, the calculation of these quantaties is done in a reliable and precise manner with LES simulation using actuator line or actuator disk models. READ MORE

5. 4. Evaluation and optimization of PolyCor - a single-use Coriolis flowmeter

   University essay from Umeå universitet/Institutionen för fysik

   Author : Evelina Ekström; [2018]
   Keywords : Coriolis; flowmeter; PolyCor; compensation model;

   Abstract : In the pharmaceutical industry it has become common to use single-use components in the production line to save time and money. Therefore, a team at General Electric started to develop a single-use Coriolis flowmeter, PolyCor M13, targeted at liquid chromatography systems. READ MORE

6. 5. Validation of a vortex panel method for aerodynamics and aero-elasticity of Wind Turbine

   University essay from KTH/Kraft- och värmeteknologi

   Author : Antoine Thibierge; [2018]
   Keywords : ;

   Abstract : Ardema3D is a new type of vortex free model code that can simulate wind turbines. This code has been developed in order to replace the state of the art model, the blade element momentum (BEM). READ MORE
