21. Computation and Analysis of EGR Mixing in Internal Combustion Engine Manifolds
Abstract : This thesis deals with turbulent mixing processes occurring in internal combustion engines, when applying exhaust gas recirculation (EGR). EGR is a very efficient way to reduce emissions of nitrogen oxides (NOx) in internal combustion engines. READ MORE

22. Modeling and Control of EGR on Marine Two-Stroke Diesel Engines
Abstract : The international marine shipping industry is responsible for the transport of around 90% of the total world trade. Low-speed two-stroke diesel engines usually propel the largest trading ships. This engine type choice is mainly motivated by its high fuel efficiency and the capacity to burn cheap low-quality fuels.

25. Large Eddy Simulation of Turbulent Swirling Flows in Combustor Related Geometries
Abstract : This thesis deals with the physics of turbulent swirling flows. Large eddy simulation (LES) method is used to investigate the vortex breakdown process, the precessing vortex core (PVC), and the effect of swirl number and flow field configuration on swirling flows. The study is based on an open source CFD code, \textit{OpenFoam}. READ MORE
