A Posteriori Error Estimation for a Dual Mixed Finite Element Approximation of Non–newtonian Fluid Flow Problems

چکیده
A dual mixed finite element method, for quasi–Newtonian fluid flow obeying to the power law, is constructed and analyzed in [8]. This mixed formulation possesses local (i.e., at element level) conservation properties (conservation of the momentum and the mass) as in the finite volume methods. We propose here an a posteriori error analysis for this mixed formulation.

A Posteriori Error Estimation for a Dual Mixed Finite Element Method for Quasi–newtonian Flows Whose Viscosity Obeys a Power Law or Carreau Law
Abstract: A dual mixed finite element method, for quasi–Newtonian fluid flow obeying the power law or the Carreau law, is constructed and analyzed in Farhloul–Zine [13]. This mixed formulation possesses good local (i.e., at element level) conservation properties (conservation of the momentum and the mass) as in the finite volume methods. In Farhloul–Zine [12], we developed an a posteriori error...
متن کاملDiscontinuous Galerkin Finite Element Approximation of Quasilinear Elliptic Boundary Value Problems Ii: Strongly Monotone Quasi-newtonian Flows
In this article we develop both the a priori and a posteriori error analysis of hp– version interior penalty discontinuous Galerkin finite element methods for strongly monotone quasi-Newtonian fluid flows in a bounded Lipschitz domain Ω ⊂ R, d = 2, 3. In the latter case, computable upper and lower bounds on the error are derived in terms of a natural energy norm which are explicit in the local ...
متن کاملApproximation of a Nonlinear Elliptic Problem Arising in a Non-newtonian Fluid Flow Model in Glaciology
The main goal of this article is to establish a priori and a posteriori error estimates for the numerical approximation of some non linear elliptic problems arising in glaciology. The stationary motion of a glacier is given by a non-Newtonian fluid flow model which becomes, in a first twodimensional approximation, the so-called infinite parallel sided slab model. The approximation of this model...
متن کاملAdaptive Discontinuous Galerkin Methods for Eigenvalue Problems Arising in Incompressible Fluid Flows
In this article we consider the a posteriori error estimation and adaptive mesh refinement of discontinuous Galerkin finite element approximations of the hydrodynamic stability problem associated with the incompressible Navier–Stokes equations. Particular attention is given to the reliable error estimation of the eigenvalue problem in channel and pipe geometries. Here, computable a posteriori e...
متن کاملRecent Advances on Explicit Variational Multiscale a Posteriori Error Estimation for Systems
In 1995 the genesis of stabilized methods was established by Professor Hughes from the standpoint of the variational multiscale theory (VMS). By splitting the solution into resolved and unresolved scales, it was unveiled that stabilized methods take into account an approximation of the unresolved scales or error into the finite element solution. In this work, the VMS theory is exploited to form...
