6. Multidisciplinary Design in Aeronautics, Enhanced by Simulation-Experiment Synergy
Sammanfattning : 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. LÄS MER
7. Contributions to Variable Fidelity MDO Framework for Collaborative and Integrated Aircraft Design
Sammanfattning : The thesis develops computational tools for early stages of the aircraft design process. The work focuses on a framework which allows several design teams concurrently to develop a baseline concept into a configuration which meets requirements and whose aerodynamics has been assessed by flight simulation.

8. Acceleration of Compressible Flow Simulations with Edge Using Implicit Time Stepping
Sammanfattning : Computational fluid dynamics (CFD) is a significant tool routinely used indesign and optimization in aerospace industry. Often cases with unsteadyflows must be computed, and the long compute times of standard methods hasmotivated the present work on new implicit methods to replace the standardexplicit schemes. LÄS MER
9. Acceleration of Compressible Flow Simulations with Edge using Implicit Time Stepping
Sammanfattning : Computational fluid dynamics (CFD) has become a significant tool routinely used in design and optimization in aerospace industry. Typical flows may be characterized by high-speed and compressible flow features and, in many cases, by massive flow separation and unsteadiness. LÄS MER
10. CFD Methods for Predicting Aircraft Scaling Effects
Sammanfattning : This thesis deals with the problems of scaling aerodynamic data from wind tunnel to free flight conditions. The main challenges when this scaling should be performed is how the model support, wall interference and the potentially lower Reynolds number in the windtunnel should be corrected. LÄS MER
