In this work, we present an application of an Arnoldi-based model order reduction (MOR) technique on squeezed-film damping (SQFD) effects for arbitrarily-shaped perforated geometries. The compact models generated by this approach not only can be easily inserted into a system-level modeling package for transient and frequency analysis, but also accounts for the effect of flow impedance of each perforation. The simulated results of the reduced models show good agreement with the experimental results. We also demonstrated that this approach is at least 100 times faster than previous works on perforated SQFD damping simulation.
