Within 100 years of the Wright Brother's first flight, we are already approaching the top of aviation’s technological S-curve. Breakthrough technical improvements have resulted in an undeniable increase in efficiency and range, but today’s aircrafts are still relatively inefficient resulting in a large amount of air and noise pollution. In order...

Flare-gas is rest gas from exploration and refining operations. Flare-gas at refineries is a mixture of several production processes’ rest gas. Usually these rest gasses are flared to the atmosphere or re-used as fuel gas after compressing and cleaning it. At Shell Pernis Refinery currently Liquid Ring Compressors are used to compress flare-gas....

The vertical tail size of a multi-engine aircraft is typically driven by the directional control requirement during one-engine-inoperative flight. This results in the vertical tail being over-sized for most regularly occurring flight conditions. By adding thrust vectoring technology to an aircraft, the vertical tail can be designed to cope with...

Atmospheric free flight scaled flight testing is an affordable way to investigate the dynamic properties of an aircraft, while enabling a wider range of test possibilities than a windtunnel. This research is the first step into the development of a scaled flight testing model and as such will highlighted the difficulties and discrepancies which...

The emission of green-house gases, such as carbon-dioxide, has been increasing rapidly in the last 50 years. Leading to an increase in the overall temperature, melting polar ice, rising sea-levels and more natural disasters. Aviation is one of the causes of these emissions. The efficiency of aircraft engines can be improved by improving the...

The use of advancements in computing technology has enabled designers to perform more thorough and more detailed design studies. Multidisciplinary Design Optimization (MDO) architectures provide users with guidelines on how to structure their MDO problem, including the linking of disciplines and how to perform the optimization. However, complex...

The effect of aviation emissions on human-induced climate change has become a major concern in the last decades. The reduction of emissions, such as CO2 and NOx, is an important matter because of the predicted increase of the aviation market in the future years. The application of alternative fuels, such as hydrogen, and new combustion methods ...

In this study a full CFD-CSD FSI method is developed, extended with a modal approach, to assess the potential flutter behavior of the SNL 100-m wind turbine blade. The FSI method is based on the existing FOAM-FSI framework and extended with a non-linear beam model. The analysis consists of four steps: non-linear steady state FSI deformation of...

The Reynolds-averaged Navier-Stokes equations are numerically solved in a segregated manner, along with the Spalart-Allmaras turbulence model. The Galerkin as well as multiple stabilized finite element formulations are derived for the Spalart-Allmaras turbulence model, and tested for robustness. For a turbulent channel flow and a backward facing...
