POD-based technique for 3D flow reconstruction using 2D data set
Résumé
We propose a technique, based on proper orthogonal decomposition, for reconstructing a fully developed 3D flow starting from spatially restricted measurement of the flow. The POD provides a basis of spatially coherent structures for the description of the 3D flow under study. We demonstrate that the 3D reconstruction, from spatially restricted measurement, can ideally be performed without loss of information as far as the transfer matrix, computed from the POD modes, is invertible.
