At high supersonic flight speeds or with a highly cooled surface, there is a strong density gradient across the boundary layer. Close to the surface the gas is cool and of low-temperature molecular weight; at the outer edge of the boundary layer the gas is hot and may be partially dissociated, so that its density is lower by a factor of 10 - 20. At the same time a strong centrifugal acceleration is produced by the body curvature, and this outward acceleration acts in the direction of decreasing density. The question arises as to whether this destabilizing effect of the acceleration field in a density gradient is sufficient to overcome the stabilizing effect of the increasing angular momentum of the fluid in the outward direction. The conclusion is drawn that the strong stabilizing effect of the outward increase in angular momentum is always dominant in the laminar boundary layer. (Author).

Volume IV of the High Speed Aerodynamics and Jet Propulsion series. Contents of this volume include: Introduction, by F.K. Moore; Laminar Flow Theory, by P.A. Lagerstrom; Three-Dimensional Laminar Boundary Layers, by A. Mager; Theory of Time-Dependent Laminar Flows, by Nicholas Rott; Hypersonic Boundary Layer Theory, by F.K. Moore; Laminar Flows with Body Forces, by Simon Ostrach; Stability of Laminar Flows, by S.F. Shen. Originally published in 1964. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
