2. Multidisciplinary Design in Aeronautics, Enhanced by Simulation-Experiment Synergy
Abstract : This thesis covers some aspects of current aircraft design, and presents how experiment and simulation are used as tools. Together they give enhanced effects over employing either one separately. The work presented has been produced using both simulations and experiments. READ MORE

3. Methodologies for RANS-LES interfaces in turbulence-resolving simulations
Abstract : Hybrid Reynolds-Average Navier-Stokes (RANS)-Large-Eddy Simulations (LES) techniques are now seen by the aeronautical industry as the most promising turbulence-resolving approaches for complex high-Reynolds-number turbulent flows with regard to cost and accuracy. However, connecting RANS and LES simulated flows is a challenging task and needs special attention in order to increase simulation robustness and accuracy. READ MORE

4. Real Time Drag Minimization
Abstract : This thesis focuses on the use of multiple redundant control surfaces to increase performance during flight. There is no clear-cut definition of performance. It may differ between applications, but here, the amount of drag for a given flight condition is used. READ MORE

5. Optimal Design of Natural and Hybrid Laminar Flow Control on Wings
Abstract : Methods for optimal design of different means of control aredeveloped in this thesis. The main purpose is to maintain thelaminar flow on wings at a chord Reynolds number beyond what isusually transitional or turbulent. READ MORE
