Interfacial fluid dynamics is important in areas ranging from the flight of an aircraft to the flow of blood in the heart, and an area of active research and development owing to improved analytical, experimental, and computational techniques. This book describes the latest methods and applications in the field. Written by an internationally recognized panel of experts in both theory and experimentation, coverage is organized around five topics: Benard and thermocapillary instabilities, shear and pressure induced instabilities, waves and dispersions, multiphase systems, and complex flows. This comprehensive volume will interest a broad audience of graduate students, faculty, and researchers in mechanical, aerospace, materials, and chemical engineering, as well as in applied mathematics and physics.
