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. CFD Optimization of Hydrofoiling Concept for A New Era of Sea Transports
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : The aim of this master thesis is to develop and optimize the main wing of a T-shaped hydrofoil for a small passenger vessel called FoilCart. The project is in collaboration with KTH Maritime Robotic Lab. The existing prototype of the hydrofoil is built by a company called ZPARQ\cite{Zparq}, but the efficiency of the main wing is not optimized. LÄS MER
3. Inverse Atmospheric Dispersion Modeling in Complex Geometries
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : In the event of a radioactive release in an urban environment the consequent response mustbe swift and precise. As soon as first responders have correct information, they can make anaccurate risk assessment. However, if the position, release rate and time of the radioactiverelease is unknown it is hard to know how the pollutant will spread. LÄS MER
4. A comparison of pressurised cylinders in HIP systems using CFD and FEM
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : A hot isostatic press (HIP) is a system which utilises high temperatures and pressure in order to densifyand enhance the material properties of components in the aerospace, automotive and additive manufacturingindustries, to mention a few. Quintus is a world leading manufacturer of HIP systems, and this master’s thesiswork has been written in collaboration with them. LÄS MER
5. Development and validation of an improved wall-function boundary condition for computational aerodynamics
Master-uppsats, KTH/Strömningsmekanik och Teknisk AkustikSammanfattning : Computational Fluid Dynamics is a powerful and widely used tool for developing projectsthat concern flow motion, in very different fields. Industrial CFD solvers are continuouslydeveloped with the aim of improving accuracy and reducing the computational cost of thesimulations. LÄS MER
