3. Aerodynamic Investigation of Leading Edge Contouring and External Cooling on a Transonic Turbine Vane
Abstract : Efficiency improvement in turbomachines is an important aspect in reducing the use of fossil-based fuel and thereby reducing carbon dioxide emissions in order to achieve a sustainable future. Gas turbines are mainly fossil-based turbomachines powering aviation and land-based power plants. READ MORE

4. Realistic simulations of delta wing aerodynamics using novel CFD methods
Abstract : The overall goal of the research presented in this thesis is to extend the physical understanding of the unsteady external aerodynamics associated with highly maneuverable delta-wing aircraft by using and developing novel, more efficient computational fluid dynamics (CFD) tools. More specific, the main purpose is to simulate and better understand the basic fluid phenomena, such as vortex breakdown, that limit the performance of delta-wing aircraft. READ MORE

5. Aerothermal Study of Intermediate Turbine Ducts
Abstract : An intermediate turbine duct guides the flow from the smaller diameter high pressure turbine to the downstream larger diameter intermediate or low pressure turbine. It is typically equipped with a structural vane transferring loads for the core to the external parts, and supplies the core with necessary services such as oil and air. READ MORE
