Finite volume POD-Galerkin stabilised reduced order methods for the parametrised incompressible Navier-Stokes equations. (arXiv:1710.11580v2 [math.NA] UPDATED)
来源于:arXiv
In this work a stabilised and reduced Galerkin projection of the
incompressible unsteady Navier-Stokes equations for moderate Reynolds number is
presented. The full-order model, on which the Galerkin projection is applied,
is based on a finite volumes approximation. The reduced basis spaces are
constructed with a POD approach. Two different pressure stabilisation
strategies are proposed and compared: the former one is based on the supremizer
enrichment of the velocity space, and the latter one is based on a pressure
Poisson equation approach. 查看全文>>
