2 PhD Positions on The Delft Laminar Hump

The transition of airflow from laminar to turbulent state is a major contributor to aerodynamic drag and consequently aircraft emissions. Often, unavoidable modifications of the wing surface, such as panel joints or skin deformations decrease the extent of laminar airflow by promoting transition. However, through our research, we showed that this is not always the case. In a recent breakthrough, our team discovered the “Delft Laminar Hump”, a passive smooth surface modification. The proof-of-concept experiments showed the capability of the Hump to create an unprecedented delay of transition, effectively increasing the extent of laminar flow.

The “Running up that Hill” project aims at achieving a clear physical understanding of the interaction between laminar-turbulent transition and surface modifications such as the Delft Laminar Hump. The fundamental and technical outcomes of this work will position Hump-like surface modifications as an enabling technology for curbing environmental emissions of aviation.

In addition to fundamental work, the project is supported by leading aerospace partners such as KLM, DNW, and Deharde as well as by world-leading groups at U. Waterloo, Canada and KTH, Sweden. Opportunities for research stays with these organisations will be available within the project.
