This book was released on 1971 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study of various wall jet flows was conducted. The major areas of investigation were: The wall jet injected into still air; The wall jet under a constant-pressure main-stream flow; The wall jet subjected to an adverse pressure gradient imposed by a retarded main-stream flow with a substantially thickened initial boundary layer; The wall jet subjected to an adverse pressure gradient imposed by a retarded main-stream flow with a thickened and distorted initial boundary layer. Detailed velocity profile and local skin friction measurements were made at numerous streamwise distances from the jet slot. For the case in which no main-stream flow was present, the studies were carried out for a wide range of slot Reynolds numbers. For the wall jets with main-stream flow, selected ratios of free-stream velocity to jet velocity at the jet slot were investigated. The growth of characteristic thickness and decay of jet peak velocity is presented for all wall jet studies. Also, velocity and temperature profile similarity is described. Skin friction laws are shown for the constant-pressure wall jets and a single 'law of the wall' valid for all wall jet studies is set forth. Finally, the skin friction and velocity profile measurements are presented in tabular form. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: NDS TO ATTACH ITSELF AND FLOW ALONG THE SURFACE. A theoretical and experimental study of the effects of the surface curvature on the flow field of a two-dimensional, incompressible, turbulent jet has been made. By using a perturbation technique, the governing equations for the flow have been obtained and solved numerically. There is flow similarity for a curved-wall jet when m = 1, and for the flow of a plane wall jet when the curvature approaches infinity. Two spiral and three circular cylindrical surfaces were tested. The mean velocity profiles and static pressure distributions were measured at various stations for each surface. In addition, the point of separation was found for Reynolds numbers, based on the nozzle width, in the range of 500 to 4000. The growth rates of the jet width and the rate of decay of the maximum velocity were deduced from the velocity measurements. (Modified author abstract).

Available in PDF, EPUB and Kindle. Book excerpt: A method for calculating the growth of a turbulent wall jet in streaming flow was developed. The flow is assumed to be two-dimensional, incompressible and over a plane, smooth wall. Downstream variations of pressure are permitted and separation in an adverse pressure gradient may be predicted. The method incorporates procedures for matching the flow to that at the blowing slot, although it is postulated that the upstream boundary layer there is thin enough that the wall jet develops without an unmixed wake (i.e. there is not a minimum in the mean-velocity profile). The method incorporates four integral momentum equations taken from the wall to various points in the flow. The calculation of the outer shearing stress, although empirical, is based on the large-eddy equilibrium hypothesis and therefore has some foundation. The remaining empiricism in the method is based on measurements in self-preserving wall jets. The method was used to predict the jet-momentum coefficient required to suppress separation over a trailing-edge flap attached to a thin aerofoil. Plausible curves have been obtained using assumed values of upstream boundary layer at the slot. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: obtained are still severely limited to low Reynolds numbers (about only one decade better than direct numerical simulations), and the interpretation of such calculations for complex, curved geometries is still unclear. It is evident that a lot of work (and a very significant increase in available computing power) is required before such methods can be adopted in daily's engineering practice. I hope to l"Cport on all these topics in a near future. The book is divided into six chapters, each· chapter in subchapters, sections and subsections. The first part is introduced by Chapter 1 which summarizes the equations of fluid mechanies, it is developed in C~apters 2 to 4 devoted to the construction of turbulence models. What has been called "engineering methods" is considered in Chapter 2 where the Reynolds averaged equations al"C established and the closure problem studied (§1-3). A first detailed study of homogeneous turbulent flows follows (§4). It includes a review of available experimental data and their modeling. The eddy viscosity concept is analyzed in §5 with the l"Csulting ~alar-transport equation models such as the famous K-e model. Reynolds stl"Css models (Chapter 4) require a preliminary consideration of two-point turbulence concepts which are developed in Chapter 3 devoted to homogeneous turbulence. We review the two-point moments of velocity fields and their spectral transforms (§ 1), their general dynamics (§2) with the particular case of homogeneous, isotropie turbulence (§3) whel"C the so-called Kolmogorov's assumptions are discussed at length.
