Journal ArticleDOI
Comparison of some finite element methods for solving the diffusion-convection-reaction equation
TL;DR: It is shown that the classical SUPG method is very similar to an explicit version of the Characteristic-Galerkin method, whereas the Taylor-Galerskin method has a stabilization effect similar to a sub-grid scale model, which is in turn related to the introduction of bubble functions.
Journal ArticleDOI
Stabilized finite element approximation of transient incompressible flows using orthogonal subscales
TL;DR: In this paper, a stabilized finite element method is proposed to solve the transient Navier-Stokes equations based on the decomposition of the unknowns into resolvable and subgrid scales.
Journal ArticleDOI
A general algorithm for compressible and incompressible flow—Part I. the split, characteristic‐based scheme
O. C. Zienkiewicz,Ramon Codina +1 more
TL;DR: A novel algorithm is outlined which can be used for the solution of both compressible and incompressible Navier-Stokes or Euler equations and introduces a rational form of balancing dissipation.
Journal ArticleDOI
Stabilization of incompressibility and convection through orthogonal sub-scales in finite element methods
TL;DR: Two apparently different forms of dealing with the numerical instability due to the incompressibility constraint of the Stokes problem are analyzed and it is shown here that the first method can also be recast in the framework of sub-grid scale methods with a particular choice for the space ofSub-scales.
Journal ArticleDOI
A stabilized finite element method for generalized stationary incompressible flows
TL;DR: A finite element formulation for the numerical solution of the stationary incompressible Navier–Stokes equations including Coriolis forces and the permeability of the medium using the algebraic version of the sub-grid scale approach.
