Finite Element Methods for Navier-Stokes Equations: Theory and Algorithms
TL;DR: This paper presents the results of an analysis of the "Stream Function-Vorticity-Pressure" Method for the Stokes Problem in Two Dimensions and its applications to Mixed Approximation and Homogeneous Stokes Equations.
BookDOI
Finite element approximation of the Navier-Stokes equations
TL;DR: A mixed finite element method for solving the stokes problem and the time-dependent navier-stokes equations are presented.
Journal ArticleDOI
DG Approximation of Coupled Navier-Stokes and Darcy Equations by Beaver-Joseph-Saffman Interface Condition
Vivette Girault,Béatrice Rivière +1 more
TL;DR: This work couple the incompressible steady Navier-Stokes equations with the Darcy equations, by means of the Beaver-Joseph-Saffman's condition on the interface, to prove existence of a weak solution as well as some a priori estimates.
Journal ArticleDOI
Two-grid finite-element schemes for the transient Navier-Stokes problem
TL;DR: This work semi-discretizes in space a time-dependent Navier-Stokes system on a three-dimensional polyhedron by finite-elements schemes defined on two grids by measuring the contribution of u H to the error analysis in the L 2 norm in space and time.
Journal ArticleDOI
Mortar multiscale finite element methods for Stokes---Darcy flows
TL;DR: Stability and a priori error estimates in terms of the fine subdomain scale $$h$$h and the coarse mortar scale $$H$$H are established for fairly general grid configurations, assuming that the mortar space satisfies a certain inf-sup condition.
