1. Large Eddy Simulation of Atomizing Sprays
Sammanfattning : Liquid-gas two-phase flows occur frequently in daily life, in nature e.g. falling rain drops or waves in the sea, and in industrial applications, e.g. LÄS MER
2. 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
3. Large-Eddy Simulation for Computing the Flow Around Vehicles
Sammanfattning : The feasibility of the use of large-eddy simulation (LES) in external vehicle aerodynamics is investigated. The computational requirement for LES of the full size car at road conditions is beyond the capability of computers in the near future. Since LES cannot be used for quantitative prediction of this flow, i.e. LÄS MER
4. Large Eddy Simulation of Complex Turbulent Flows
Sammanfattning : This thesis concerns the Large Eddy Simulation methodology and its application to predict complex turbulent flows at high Reynolds numbers, and at times also with high Mach numbers. The meaning of the word ?complex? refers both to the presence of complex flow phenomena and the, often, complex geometry of man-made devices restricting the flow. LÄS MER
5. Large Eddy Simulation of Turbulent Compressible Jets
Sammanfattning : Acoustic noise pollution is an environmental aggressor in everyday life. Aero- dynamically generated noise annoys and was linked with health issues. It may be caused by high-speed turbulent free flows (e.g. LÄS MER
