Authored by a recognized expert with decades of experience and many software patents to his credit, the volume covers advances in computational fluid dynamics to showcase innovative ways to apply physical measurements and visualization patterns to solve various aero- and hydrodynamic problems. It also delves into analytical methodologies to compare and contrast with the theoretical models most commonly used in the field. Additionally, it demonstrates the significance of comprehending and managing disturbances in shear flows, discussing practical applications of the research to optimize the design of aircraft, automotive vehicles, and marine vessels, with a strong emphasis on enhancing aero- and hydrodynamic efficiency, fuel economy, and the reduction of harmful emissions.
Academia and industry readers alike will find this a useful resource to equip themselves with the tools needed to understand and address practical engineering challenges encountered in their studies or work.

Viktor V. Babenko
Prof. Viktor V. Babenko received his MSc in Mechanical Engineering from the Moscow Aviation Institute in 1963 and his PhD in Fluid and Gas Mechanics from the Institute of Hydro-aeromechanics of the National Academy of Sciences of Ukraine (NASU) in 1970. Between 1963 and 1965, he worked at the Antonov Design Bureau, a Ukrainian aircraft manufacturing company. He has been at the Institute of Hydromechanics since 1965, where he has managed research projects on boundary layers. He has been a professor since 1990, and was the Head of Department until 2000. Throughout his career, he has developed original methodologies for research on boundary layer receptivity to 2D and 3D disturbances, at flows around elastic coatings, near different cavities and ledges, in a vortex chamber, at movement of high-speed surface devices, and others. He has developed control methods for coherent vortical structures arising at various types of flows. From 1989 to 2006, he was a member of the Scientific Council of the Institute of Hydromechanics NASU, and since 2000 he has been a member of the Scientific Councils of the Universities of Civil Aviation and Polytechnic in Kiev.
