Coherency Matrix-based Proper Orthogonal Decomposition with Application to Wind Field Simulation
Proper Orthogonal Decomposition (POD) offers a powerful modal transformation tool for stochastic dynamics. In this paper, coherency matrix-based proper orthogonal decomposition (CPOD) is presented as an innovative form of the POD based on cross power spectral density matrices. By introducing a discretizing scheme, the CPOD-based spectral representation method is obtained for use in stochastic simulation. Some criteria are also proposed that allow the truncation order of CPOD to be conveniently determined. A numerical example to illustrate application of the proposed method for simulation of a wind velocity field is given.
