1. Large Eddy Simulation of Impinging Jets
Sammanfattning : This thesis deals with Large Eddy Simulation (LES) of impinging air jets. The impinging jet configuration features heated circular jets impinging onto a flat plate. The problem addressed here is of generic nature, with applications in many engineering devices, such as cooling of components in gas turbines, in cars and electronic devices. LÄS MER
2. Hydrogeological Methods in Geotechnical Engineering: Applied to settlements caused by underground construction
Sammanfattning : Improvement in the infrastructure in urban areas generally involves underground construction with tunneling and deep excavations. One important consideration when constructing in cities founded on soft soil is settlement resulting from groundwater drawdown. The potential cost of excessive settlement in these projects is immense. LÄS MER
3. Modelling Techniques for Large-Eddy Simulation of Wall-Bounded Turbulent Flows
Sammanfattning : Large-eddy simulation (LES) is a highly accurate turbulence modelling approach in which a wide range of spatial and temporal scales of the flow are resolved. However, LES becomes prohibitively computationally expensive when applied to wall-bounded flows at high Reynolds numbers, which are typical of many industrial applications. LÄS MER
4. Baltic shore-lands facing climate change
Sammanfattning : This thesis provides new insight concerning drivers behind differences in arthropod diversity and abundance in Baltic shore ecosystems and how the arthropod communities might be affected when the conditions in the Baltic Sea are altered due to climate change. The focus has been on climate related changes that are unique for coastal ecosystems, especially sea level rise and changes in the inflow of marine nutrients. LÄS MER
5. Computational fluid dynamics for dispersion calculation in urban surroundings
Sammanfattning : Increased knowledge on dispersion processes in urban environment will enhance the ability in the society to handle events where releases of toxic substances can occur. Also, the ability to increase preparedness at locations where such events potentially can emerge. LÄS MER
