Optimization with the time-dependent Navier-Stokes equations as constraints
In this paper, optimal distributed control of the time-dependent Navier-Stokes equations is considered. The control problem involves the minimization of a measure of the distance between the velocity field and a given target velocity field. A mixed numerical method involving a quasi-Newton algorithm, a novel calculation of the gradients and an inhomogeneous Navier-Stokes solver, to find the opt...
متن کاملDiscontinuous Time Relaxation Method for the Time-Dependent Navier-Stokes Equations
A high-order family of time relaxation models based on approximate deconvolution is considered. A fully discrete scheme using discontinuous finite elements is proposed and analyzed. Optimal velocity error estimates are derived. The dependence of these estimates with respect to the Reynolds number Re is O Re eRe , which is an improvement with respect to the continuous finite element method where...

متن کاملA Discontinuous Subgrid Eddy Viscosity Method for the Time-Dependent Navier-Stokes Equations
In this paper we provide an error analysis of a subgrid scale eddy viscosity method using discontinuous polynomial approximations for the numerical solution of the incompressible Navier–Stokes equations. Optimal continuous in time error estimates of the velocity are derived. The analysis is completed with some error estimates for two fully discrete schemes, which are first and second order in t...
متن کاملEfficient Time Integration for Discontinuous Galerkin Method for the Unsteady 3d Navier-stokes Equations
We look at adaptive time integration in the context of discontinuous Galerkin methods for the three dimensional unsteady compressible Navier-Stokes equations. Several explicit and implicit schemes will be compared. Philipp Birken, Gregor Gassner, Mark Haas and Claus-Dieter Munz
