Abstract

There is a need for developing a tool that combines data from Computational Fluid Dynamics (CFD) simulations, Experimental Fluid Dynamics (EFD), and Flight Fluid Dynamics (FFD) in the framework of Reduced Order Models (ROM). The “Gappy” Proper Orthogonal Decomposition (POD) is an extension of POD that allows consideration of incomplete data sets and can be used to enrich the experimental results to the size of CFD simulations. In this paper, a method based on an iterative application of POD basis extraction technique is implemented for reconstruction of the missing experimental snapshots, and the method’s accuracy is compared with experimental values.
