Book Description
The flow in the tail region of a body of revolution is a complex one since there the boundary layer often grows to a thickness many times the local radius of the body and there results a strong interaction between the boundary layer and the external potential flow. The influence of making simplifying assumptions concerning the flow in this region in conventional drag-calculation methods is discussed, and assessed by incorporating a method which takes into account the effects of the thick axisymmetric boundary-layer near the tail in an approximate manner. It is shown that this modification leads to a drag-calculation method which gives consistently accurate prediction of the viscous resistance of a wide variety of bodies of revolution. (Author).

Pages : 6
Book Description
The research carried out under this contract can be divided into three main sections, namely (1) an experimental study of the thick, turbulent boundary-layer near the tail of a body of revolution, (2) methods of calculating the thick, axisymmetric, turbulent boundary-layer and its interaction with the potential flow, and (3) calculation of the viscous resistance of bodies of revolution at zero incidence. The progress made in each of these areas is reviewed.

Experimental Hydrodynamics for Flow Around Bodies
Author: Viktor V. Babenko
Publisher: Academic Press
ISBN: 0128234482
Category : Technology & Engineering
Languages : en
Pages : 675
Book Description
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
