16. Large Eddy Simulation of the Flow around a High-Lift Airfoil
Abstract : 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. READ MORE

17. Super-grid Linear Eddy Model (SG-LEM): Efficient mode- and regime-independent combustion closure for Large Eddy Simulation (LES)
Abstract : Next-generation combustion technology such as ‘lean burn’ and HCCI (Homogeneous Charge Compression Ignition) present new challenges for combustion modelling. The presence of locally varying combustion modes (premixed vs. non-premixed) and regimes (fast/non-fast chemistry vs. READ MORE

18. Flow Duct Acoustics : An LES Approach
Abstract : The search for quieter internal combustion engines drives the quest for a better understanding of the acoustic properties of engine duct components. Simulations are an important tool for enhanced understanding; they give insight into the flow-acoustic interaction in components where it is difficult to perform measurements. READ MORE

19. A Large Eddy Simulation Based Fluid-Structure Interaction Methodology with Application in Hydroelasticity
Abstract : The phenomenon of hydroelasticity is a subarea of Fluid-Structure Interaction (FSI) and of major importance in many engineering applications related to hydrodynamics and naval architecture e.g. READ MORE

20. Approaching Large Eddy Simulation of Cavitating Flows for Marine Applications
Abstract : Cavitation is a major concern in naval craft design as well as in the shipping industry. Although the nature of cavitation is not fully understood, propellerdesigns are presently improved by experimental analysis of the phenomena. READ MORE
