Book Description
An experimental investigation of laminar boundary-layer separation induced by a trailing edge ramp on a flat plate was conducted at Mach numbers of 6, 8, and 10. The tests were conducted over a range of Reynolds numbers. Longitudinal and spanwise surface pressure distributions, pitot pressure profiles, and shadowgraph pictures were used to investigate the two-dimensionality of the flow and the effects of model geometry, angle of attack, Reynolds number, ramp angle, and mass removal from the separation region. Data are presented to show that laminar, two-dimensional boundary-layer reattachment, not limited by model geometry, was obtained. These data are compared to the integral-moment theory of Lees and Reeves as modified by Klineberg. It is also shown that a separation region can be reduced or even eliminated by removing mass at the hinge line. (Author).

Book Description
Given the Navier-Stokes equations in general orthogonal curvilinear coordinates, specific equations for particular cases are indicated. In the notation of singular perturbation theory, the first approximation to the inner expansion (boundary-layer) is solved in simple cases. Some remarks are also made concerning shock-wave boundary-layer interactions; in particular, no approximation to the equations is found in the immediate vicinity of the interaction. Base flows are also mentioned. (Author).
