Spatial amplification and Squire's theorem
Abstract
Spatial and temporal model disturbances to a two-dimensional shear flow are considered. The 'zarf' or absolute neutral curve for a Blasius flow is obtained and the lower branch is shown to differ from the two-dimensional neutral curve. For a fixed frequency the most amplified spatial oscillation, as the Reynolds number varies, is not two-dimensional but very nearly so.
