On the convergence order of the finite element error in the kinetic energy for high Reynolds number incompressible flows
García-Archilla, Bosco; John, Volker; Novo, Julia (Elsevier, 2021-11)The kinetic energy of a flow is proportional to the square of the L2(Ω) norm of the velocity. Given a sufficient ...

POD-ROMs for Incompressible Flows Including Snapshots of the Temporal Derivative of the Full Order Solution
García-Archilla, Bosco; John, Volker; Novo, Julia (Society for Industrial and Applied Mathematics (SIAM), 2023)In this paper we study the influence of including snapshots that approach the velocitytime derivative in the numerical ...

Second order error bounds for POD-ROM methods based on first order divided differences
García-Archilla, Bosco; John, Volker; Novo, Julia (Elsevier, 2023)This note proves for the heat equation that using BDF2 as time stepping scheme in POD-ROM methods with snapshots based on difference quotients gives both the optimal second order error bound in time and pointwise estimates.
