The book "Transition Location Effect on Shock Wave Boundary Layer Interaction" offers a comprehensive analysis of experimental and numerical results aimed at reducing separation caused by shock waves. It examines how close the transition zone should be positioned to the shock wave to achieve a beneficial interaction of the turbulent boundary layer. The authors present findings obtained through advanced flow measurement techniques, highlighting aspects such as the transition position, boundary layer characteristics, and the detection of shock wave configurations. The book includes numerous experimental case studies and CFD simulations that provide valuable insights into flow structure. It addresses both RANS/URANS methods for designing experimental test areas and advanced techniques such as LES, hybrid methods, and DNS to thoroughly investigate the interactions between transition and shock waves. The studies presented in this work were conducted as part of the TFAST project by sixteen different partners and are aimed at academics and professionals dealing with the aerodynamics of internal and external flows, as well as students in the field of aerospace and propulsion systems.
