Towards Effective Flow Control and Mitigation of Shock Effects in Aeronautical Applications

****

This open-access book reports on both experimental and numerical findings from the H2020-funded project TEAMAero (Towards Effective Flow Control and Mitigation of Shock Effects in Aeronautical Applications). It covers novel contributions on improving the fundamental understanding of the physics of shock wave boundary layer interaction, developments in ow control for mitigation of shock effects, and advanced numerical methods for predicting those effects. All in all, this book offers a timely snapshot of research and developments in numerical methods for flow analysis and control, with a special emphasis on high-speed flows. It offers extensive information to both researchers and professionals.

This book is open access, which means that you have free and unlimited access Covers both experimental and numerical findings Reports on the results of the H2020-funded project TEAMAero Describes applications to both fundamental and industrial problems

Autorentext

Pawel Flaszynski studied mechanical engineering and obtained a Ph.D. in turbomachinery flows and inverse design from Gdansk University of Technology (Poland) in 2002. He then continued his research in the field of aerodynamics and numerical methods, focusing on flow control (streamwise vortex generators) in subsonic and transonic flows, as well as shock-wave/boundary-layer interactions. In 2018, he was awarded a prize for his research on the development of flow control methods in aeronautics by the Ministry of Science and Higher Education (Poland). Since 2014, he has been a professor at the Institute of Fluid Flow Machinery (Polish Academy of Sciences) and the head of the aerodynamics department. He has collaborated on, and coordinated, European projects related to shock-wave/boundary-layer interactions and flow control in compressors, gas turbines, and aircraft wings. He is a member of the European Turbomachinery Society (EUROTURBO) and a representative in the International Society for Airbreathing Engines (ISABE).

Holger Babinsky studied aerospace engineering at Stuttgart University in Germany. He obtained a Ph.D. in hypersonic aerodynamics from Cranfield University (UK) in 1994. After 18 months as a research associate at the Shock Wave Research Center of Tohoku University in Sendai, Japan, he returned to the UK to take up a position in the Department of Engineering of the University of Cambridge. He is now the head of fluid mechanics, energy, and turbomachinery as well as a fellow of Magdalene College. His main areas of research are in the field of experimental aerodynamics and associated measurement techniques. Apart from shock-wave/boundary-layer interactions which he has studied for more than 30 years, his current research includes unsteady aerodynamics, road vehicle aerodynamics, and flow control for aircraft wings and engine inlets. He is a fellow of the Royal Academy of Engineering, the Royal Aeronautical Society, and the American Institute of Aeronautics and Astronautics.

Piotr Doerffer is a professor at the Institute of Fluid Flow Machinery (a member of the Polish Academy of Sciences, IMP PAN) in Gdansk, Poland. He is involved in both experimental and numerical analyses of transonic flows with shock waves in nozzles and turbine or compressor cascades. His extensive international cooperation stems from long-term research internships at the engineering department of Cambridge University, the mechanical faculty of Karlsruhe University, and the fluid dynamicsdepartment of DLR in Göttingen. The main focus of his work has been flow control aimed at reducing shock-wave-induced separation. He has been actively involved in European collaborative research projects, including EUROSHOCK, AITEB, TLC, ERICKA, FACTOR E-BREAK, as well as coordinating projects like UFAST and TFAST. He has also coordinated Marie Curie projects. Throughout his research career at IMP PAN, he has progressed from an assistant position to the deputy director of the institute.
