Guest lecture by Prof. van Ingen (Some highlights of research at TU Delft on airfoil aerodynamics - 10.09.2020)

Abstract:

•    The e ^N method for transition prediction, past, present and possible future developments.
•    The Timman method of airfoil design using conformal transformation. Some history and possible future developments.
•    The laminar separation bubble revisited.

We were pleased to host Prof. van Ingen in our institute where he delivered a lecture on his life's work in linear stability theory and transition predictionalong with some of his recent work towards the development of the full Improved e ^N   method. (Link to the video is shown below).

Bio : Prof. van Ingen was born in 1932, graduated in 1954 from the Dep. of Aerospace Engineering at Delft University. He was selected to help build up the Department at Delft that was started in 1940. In 1952, he was charged as a student-assistant with the development of a research program for the low-speed-low-turbulence wind tunnel. A long-lasting research program on viscous flows was established with special emphasis on boundary layer control for drag and high lift augmentation. From this time on, he concentrated on viscous flow research such as transition prediction. This resulted in 1956 in the publication of his now-famous e ^N method for transition prediction, which has remained in use until the present time.
 In 1966 he obtained his Ph.D. from TU Delft on a research project on laminarization by suction. He spent a year at the Lockheed Georgia Research Lab, where he did pioneer research on the use of Computer graphics for airfoil design (1966-1967). After his return to Delft, he held various positions such as an assistant, associate, and full professor.
In addition to teaching and research, he made an important contribution to the management of the Department of Aerospace. He also contributed to the management of TU Delft in general (eg Board member / Chairman of the Computing Center (1970-1775); co-founder of the JM Burgers Research School for Fluid Dynamics).
For his contributions to education and research and other services to society, he was awarded in 1995 the Royal Decoration of Knight in the Order of the Dutch Lion. In 2006 he celebrated the 50th anniversary of his e ^N method for transition prediction. On this occasion, Delft Aerospace Engineering honored him with a place on its “Wall of Fame”.
