Laminar boundary layers can be loosely classified according to their structure and the circumstances under which they are created. The thin shear layer which develops on an oscillating body is an example of a Stokes boundary layer, while the Blasius boundary layer refers to the well-known similarity solution near an attached flat plate held in an oncoming unidirectional flow and Falkner–Skan. The effect of a pressure gradient on the first mode of instability of compressible subsonic and supersonic boundary layers is investigated using linear stability theory. A pressure gradient is studied that generates potential‐flow Mach number distributions at the edge of the boundary layer of the form M e =cx n, where c is a constant and x is the dimensionless streamwise by: 4.

Kluwer Academic Publ., pp 65– CrossRef Google ScholarAuthor: A. V. Dovgal. The primary and subharmonic instabilities of separating compressible subsonic two-dimensional boundary layers in the presence of a two-dimensional roughness element on a flat plate are investigated.

Although zero-gradient boundary layers reduce the flutter region in the parameter space [15,16,18,19,[22][23][24][25], boundary layers over concave walls can be . @article{osti_, title = {A method for the direct numerical simulation of hypersonic boundary-layer instability with finite-rate chemistry}, author = {Marxen, Olaf, E-mail: @ and Aeronautics and Aerospace Department, von Karman Institute for Fluid Dynamics, Chaussée de Waterloo, 72, Rhode-St-Genèse and Magin, Thierry E. and Shaqfeh, Eric S.G. and Iaccarino.
