Enablers for robust POD models

  title={Enablers for robust POD models},
  author={Michel Bergmann and Charles-Henri Bruneau and Angelo Iollo},
  journal={J. Comput. Physics},
This paper focuses on improving the stability as well as the approximation properties of Reduced Order Models (ROM) based on Proper Orthogonal Decomposition (POD). The ROM is obtained by seeking a solution belonging to the POD subspace and that at the same time minimizes the Navier-Stokes residuals. We propose a modified ROM that directly incorporates the pressure term in the model. The ROM is then stabilized making use of a method based on the fine scale equations. An improvement of the POD… CONTINUE READING
