With the increasing role of computational modeling in engineering design, performance estimation, and safety assessment , improved methods are needed for comparing computational results and experimental measurements. Traditional methods of graphically comparing computational and experimental results, though valuable, are essentially qualitative. Computable(More)
Keywords: Reduced order models Galerkin projection Energy method Linearized Euler equations a b s t r a c t The Galerkin projection procedure for construction of reduced order models of compress-ible flow is examined as an alternative discretization of the governing differential equations. The numerical stability of Galerkin models is shown to depend on the(More)
