Keywords: reduced order modeling, unsteady flows, fluid eigenmodes

In this article, a new reduced-order modeling approach is presented. This approach is based on fluid eigenmodes and without using the static correction. Numerical examples are presented to demonstrate the accuracy and computational efficiency of the proposed method. Based on the obtained results, it has been shown that the accurate reduced order models of unsteady flows can be constructed without using the static correction technique.
