Book Description
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).

Book Description
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).
