1. Turbulent Boundary Layer Separation and Control
Abstract : Boundary layer separation is an unwanted phenomenon in most technical applications, as for instance on airplane wings, ground vehicles and in internal flow systems. If separation occurs, it causes loss of lift, higher drag and energy losses. It is thus essential to develop methods to eliminate or delay separation. READ MORE

2. A study on axially rotating pipe and swirling jet flows
Abstract : The present study is an experimental and numerical investigation on rotating flows. A special facility has been built in order to produce a turbulent swirling jet generated by a fully developed rotating pipe flow and a Direct Numerical Simulation (DNS) code has been used to support and to complement the experimental data.

3. Numerical Modeling of Flows Related to Gas Turbine Combustors
Abstract : The thesis focuses on the numerical simulation of the flow field in gas turbine burners. Due to tougher and tougher requirements on low levels of emission of pollutants there is a need for new combustion technologies. In gas turbines one method to attain low pollutant levels is the use of lean premixed combustion. READ MORE

4. Aerothermal Investigation of an Intermediate Turbine Duct
Abstract : Intermediate turbine ducts are used to guide the flow in turbofan engines from the short-radius high-pressure turbine to the large-radius low-pressure turbine. The demand for more efficient and silent jet engines and with a reduced environmental impact requires turbofans with increasingly higher by-pass ratios. READ MORE

5. Numerical modeling of Swirling Flows in Gas Turbine Burners
Abstract : The present thesis focuses on the numerical simulation of the flowfield in gas turbine burners. Due to the higher and higher requirements regarding pollutant emissions there is a need for new combustion technologies. In gas turbines one method to obtain low pollutant levels is the use of lean premixed or partially premixed combustion. READ MORE
