Summary

Chapter 6 deals with 2-D laminar boundary-layer instabilities and their control. It covers the full range of Mach numbers from incompressible to hypersonic. Boundary-layer instabilities leading to turbulence onset is of great practical importance. This chapter reviews methods of analysis of boundary-layer stability and illustrates several linear and nonlinear mechanisms that can play a role in the breakdown to turbulence. Such understanding is intrinsic to the methods of boundary-layer instability control that are presented in the chapter. Both passive and active flow control approaches are presented.
