In 1967 LUMLEY [4] proposed an approach to the objective determination of coherent structures. The method uses an orthogonal decomposition to extract eigenvectors from two point velocity measurements, the lowest order eigenvector representing the largest structure. If the flow is homogenous, stationary or periodic the orthogonal decomposition reduces to a harmonic decomposition. These directions therefore are fit with the harmonic eigenfunctions before applying Lumley’s orthogonal decomposition to the inhomogeneous directions.
