1. Propulsion modelling of a generic submarine propeller
Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : 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. LÄS MER
2. Improving the experimental setup for ultrasound-optical tomography imaging
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : 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. LÄS MER
3. A simplified vortex method for wind turbine simulation
Master-uppsats, KTH/Strömningsmekanik och Teknisk AkustikSammanfattning : 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. LÄS MER
4. Evaluation and optimization of PolyCor - a single-use Coriolis flowmeter
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : 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. LÄS MER
5. Validation of a vortex panel method for aerodynamics and aero-elasticity of Wind Turbine
Master-uppsats, KTH/Kraft- och värmeteknologiSammanfattning : 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). LÄS MER
