Abstract
The method of snapshots for Karhunen–Loève expansion has been applied to two-dimensional, two-component hot-wire data from the first pairing region of a weakly perturbed free shear layer. Almost 90% of the fluctuation energy is captured by the first four modes. The first and the second modes contain almost equal amounts of energy, as do the third and the fourth, and the time dependence for each pair is very nearly sinusoidal with the odd modes leading in phase by π/2.
