This book was released on 1969 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: A closed form solution is developed for the rate of growth and shear stress parameter of symmetric, self-preserving wakes and jets in streaming flow. A universal shape for the mean velocity profile is assumed and enables the approximate turbulent boundary layer equation to be integrated across the flow. By choosing two different limits for the integration, two equations are developed, one of which depends on the turbulent stress at a particular non-dimensional distance from the axis of symmetry. A semi-empirical expression is developed, relating the turbulent shear stress to the ratio of the mean longitudinal rate of strain to the mean shear. This is used to give an analytical solution for the growth parameters for the full range of self-preserving jets and wakes. The theory differs in one important detail from that of Gartshore in that the axis along which the longitudinal rate of strain is identified is not the axis of symmetry but is near to the locus of inflection points of the mean velocity profile. Graphs of the functions are given for both two-dimensional and axisymmetric flow. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The development of any inhomogeneous free-turbulence flow in an incompressible fluid is predicted through the use of a general self-preservation hypothesis. The analytical solutions are verified by comparison with experimental data on mean-flow and turbulence characteristics of plane and axisymmetric jets in coaxial parallel flow with and without confinement, of an axisymmetric jet in a cross flow, and of the wake behind a self-propelled body. Emphasis is placed on the distinct turbulence structure of the various flows as revealed by the different axial variations of a shear parameter relating turbulence shear to mean velocity. The satisfactory predictions obtained by the new approach make it appear to have a more general application (e.g., to plumes and wall jets) than the examples chosen might imply. (Author).
