Experimental Hydrodynamics for Flow around Bodies explains complex novel experimental methodologies to solve a wide range of important flow problems in industry and research. The book starts by examining the fundamental physical laws necessary for the optimization of techniques for hydro-aeromechanics, heat engineering, and other disciplines related to flow. The reader is then provided with detailed explanations of novel experimental methods, along with the results of physical research. These results are also necessary for the construction of theoretical models that provide improved descriptions for numerous problems in various scientific fields.

Frequent discussions, examples of practical applications throughout the text, and foundational, theoretical materials help a range of readers engage and apply these methods to problems in fields including drag reduction, noiseless movement, optimal maneuvering, intense heat transfer, control of separated vortices, wind power, economical energy consumption, and more.

• Provides instructions on the set up of innovative experiments for drag reduction that will be of great interest to researchers in aerospace, marine and automotive engineering
• Describes, in detail, a variety of novel experiments to investigate boundary layer flow, together with experimental data that can be used with computational models
• Assists with bio-inspired hydrodynamic design by providing models of a waving fin mover and investigations of analogs of hydrobiont skin covers
