The report presents the results of an experimental investigation on the extent of separation of a turbulent boundary layer due to cylindrical protuberances, square prisms, and triangular prisms mounted on a flat plate. The effect of the separated flow on the pressure distribution along the centerline of the plate and on the surface of the attached protuberances is shown. The widths of the protuberances were 0.6 and 1.0 inch, and the ratio of protuberance height to boundary-layer thickness, h/sigma, ranged from 0.3 to 4.4. The test Mach number was 2.17, and the unit Reynolds number was 3,000,000/ft. Results from the experiment indicate that: (1) when h/sigma, the extend of separation is dependent on protuberance height and on the diameter of the cylinder or the breadth of the square prism, but when h/sigma

An investigation was conducted on a turbulent boundary layer near a smooth surface with pressure gradients sufficient to cause flow separation. The Reynolds number was high, but speeds were entirely within the incompressible flow range. The investigation consisted of measurements of mean flow, three components of turbulence intensity, turbulent shearing stress, and correlations between two fluctuation components at a point and between the same component at different points. Results are given in the form of tables and graphs. The discussion deals first with separation, and then with the more fundamental question of basic concepts of turbulent flow.

The subject is investigated with flow visualization techniques; the turbulent boundary layer on the wall of a continuous supersonic wind tunnel is used. Sizeable separated flow regions can be studied since the wall width is 38cm and the boundary layer is typically 2.5cm thick. The large scale of the experiment is required to resolve the fine details of the flow structure. The flow visualization techniques are discussed. The structure of the separated flow upstream of the obstacle is seen to change with relatively small changes in Reynolds number R; the number of vortices varies from 6 to 4 to 2 as R changes. Data are presented for large and small protuberances, but the latter are emphasized.

Separation caused by the pressure rise induced by flares has been experimentally investigated in the Mach number range of 1.5 to 5.0 and in the Reynolds number range (based on boundary-layer thickness) of 1.5X104 to 12X104. The purpose of the investigation was to determine the model geometry and flow conditions for which separation can be expected for a turbulent boundary layer of zero pressure gradient on the cylinder approaching the flare. Comparisons are made of the boundary-layer-separation characteristics of these three-dimensional flares with two-dimensional separation results from a previous investigation.
