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).

The flow field of three dimensional incompressible wall jets prototypic of thrust augmenting ejectors with large cross flow is solved using a very efficient centered-Euler scheme in an orthogonal curvilinear coordinate system. The computational model treats initial conditions with arbitrary velocity profiles at or downstream of the jet exit. An averaging approach is employed for the first few marching steps to overcome spurious numerical oscillations associated with arbitrary initial profiles. Laminar as well as turbulent wall jets are simulated. Turbulence is introduced using a two layer mixing length model appropriate to curved three-dimensional wall jets. Typical results quantifying jet spreading, jet growth, nominal separation and jet shrink effects due to cross flow are presented.

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).
