Abstract
We present a Proper Orthogonal Decomposition (POD) based Reduced Order Model (ROM) for the solution of low Mach number flow problems using three different models [1]: the Boussinesq approximation, the low Mach number limit equations, and the compressible Navier-Stokes equations. In the development of this model we carry out some strategies used previously in the solution of other problems, such as the Petrov-Galerkin projection [2], the hyper-reduction approach and the use of reduced order sub-s...
