Boundary Layer Flow over Elastic Surfaces: Compliant Surfaces and Combined Methods for Marine Vessel Drag Reduction

While other methods of drag reduction are well-known in marine R&D and ship design environments worldwide, compliant coating drag reduction remains less well-known and poorly understood. This important book presents cutting-edge techniques and findings from research sources not generally accessible by Western researchers and engineers, aiding the application and further development of this potentially important technology.

Beginning with an introduction to drag reduction that places the authors’ work on elastic surfaces and combined techniques in context, the book moves on to provide a comprehensive study of drag reduction through elastic coating with both flow and material properties considered. Coverage includes:

• Experimental findings around coherent vortical structures (CVS) in turbulent boundary layers and methods of controlling them
• Static and dynamic mechanical characteristics of elastic composite coatings, as well as new techniques and devices developed for their measurement
• Combined methods of flow control and drag reduction, including the effect of injection of polymer solutions, elastic coatings and generated longitudinal vortical structures on hydrodynamic resistance

Intended as a reference for senior engineers and researchers concerned with the drag reduction and the dynamics of turbulent boundary layer flows, Boundary Layer Flow over Elastic Surfaces provides a unique source of information on compliant surface drag reduction and the experimental techniques around it that have shown measurable and repeatable improvements over recent years.

This compilation of research findings and new techniques developed for measurement will aid R&D engineers, naval architects and senior designers in their quest to achieve drag reductions that will deliver significant efficiency savings.

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.
