Abstract

Snapshot Proper Orthogonal Decomposition (POD) is a useful tool applied to many different flows. This technique is used mainly for turbulent flows to find the most energetic structures, but it can also be used to extract dominant structures in any type of data. The method usually involves using multiple snapshots in time at one spatial location. However, a problem that can arise is when some of the data is not available in some of the snapshots due to obstructions. Several techniques have been investigated for creating data to fill in where it is missing. An example test case of a plunging NACA 0012 airfoil is used to access the efficiency and accuracy of the various fill-in techniques.
