1. Large Eddy Simulations of Separated Compressible Flows around Wing Sections
Sammanfattning : This thesis concerns numerical calculations of compressible separated flows, with and without shocks, around wing sections using Large Eddy Simulations (LES). The considered geometries are the NACA 0012 wing section and the ONERA AT15A wing section. LÄS MER
2. Experimental Studies of Separated Flow and Heat Transfer in a Ribbed Channel
Sammanfattning : The main concern of this thesis is to experimentally investigate the turbulent flow and heat transfer in a ribbed channel. Such flows are encountered in many engineering applications, e.g., gas turbine cooling. LÄS MER
3. Modal Decomposition of Separated Nozzle Flow
Sammanfattning : The applicability of two different eigenvalue algorithms coupled with an axisymmetric RANS solver to predict the eigenmodes of separated supersonic flow inside an axisymmetric convergent-divergent nozzle was investigated. These are the Arnoldi and the Dynamic Mode Decomposition (DMD) algorithms, respectively. LÄS MER
4. Communicating references in geographically separated collaborative work : an exploratory study
Sammanfattning : This thesis is about collaboration between geographically separated small enterprises and how they manage their collaborative efforts. The issue has been explored by studying how the collaborating colleagues handle references during telephone conversations. LÄS MER
5. Acquisition strategies for fat/water separated MRI
Sammanfattning : This thesis focuses on new ways to more efficiently acquire the signal for fat/water separated MRI, also known as Dixon methods. In paper I, the concept of dual bandwidths was introduced to improve SNR efficiency by removing dead times in a spin echo PROPELLER sequence. LÄS MER
