1. Macroscopic Volume and Free Volume of Polymer Blends and Pressure-densified Polymers
Sammanfattning : The macroscopic volume V as a function of pressure P and temperature T is obtained from PVT measurements. PVT data is sensitive to the state of polymers and changes therein. Moreover, PVT data gives access to the free-volume fraction. LÄS MER
2. Reportaget som kom av sig : en analys av reportaget som textform utifrån produktionsperspektivet och sändarrollen med betoning på reporterns personliga tonfall : en undersökning av reportaget i några landsortstidningar 1960-1985
Sammanfattning : Reportage is a generally accepted, yet poorly defined genre in Swedish newspaperterminology. It is usually associated with journalistic texts that are produced outside theroutines of daily news coverage; reportage features also have a more personal tone thanstandard news texts in that the reporter imparts his or her personal observations andperceptions of the scene in question.

3. Numerical Simulation of Turbulent Flows for Turbine Blade Heat Transfer Applications
Sammanfattning : Turbine blade heat transfer is an important engineering problem characterized by complex flow fields and high turbulence levels. This thesis is focused on using a full Navier-Stokes solver with two-equation eddy-viscosity models to predict external heat-transfer in single-stage, linear, two-dimensional uncooled turbine cascades.

4. Water diffusion and free volume in hydrophilic polymers
Sammanfattning : During moisture uptake in polymers, the diffusion of the water molecules is believed to occur via unoccupied voids. These voids are called free volume cavities and their sizes are continuously altered when the moisture content in the polymer is enhanced. LÄS MER
5. Large Eddy Simulation of the Flow around a High-Lift Airfoil
Sammanfattning : The work presented in this thesis concerns the efforts of conducting a Large Eddy Simulation (LES) around an airfoil. The airfoil is close to stall, near maximum lift and the Reynolds number is high. In the flow a transitional separation bubble is present. LÄS MER
