چکیده

For Stokes problem, we show how to obtain nite volume schemes from a Mixed nite element method with a well chosen numerical integration diagonalising the mass matrix. The analysis of the corresponding nite volume scheme is directly deduced from general results of mixed nite element theory. In this note, we exhibit nite volume scheme for Stokes problem and give optimal a priori error estimate. R esum e Pour le probl eme de Stokes, nous montrons comment obtenir un sch ema de type volumes nis a partir d'une m ethode el ements nis mixte duale, en utilisant une int egration num erique convenable qui diagonalise la matrice de masse. La th eorie des el ements nis mixte nous permet d'analyser ce sch ema. Dans cette note, nous exhibons un sch ema de type volumes nis pour le probl eme de Stokes et nous en donnons une estimation d'erreur a priori optimale.

A Composite Finite Difference Scheme for Subsonic Transonic Flows (RESEARCH NOTE).

This paper presents a simple and computationally-efficient algorithm for solving steady two-dimensional subsonic and transonic compressible flow over an airfoil. This work uses an interactive viscous-inviscid solution by incorporating the viscous effects in a thin shear-layer. Boundary-layer approximation reduces the Navier-Stokes equations to a parabolic set of coupled, non-linear partial diff...

2 00 7 a Convergent Finite Element - Finite Volume Scheme for the Compressible Stokes Problem Part I – the Isothermal Case

In this paper, we propose a discretization for the compressible Stokes problem with a linear equation of state ρ = p, based on Crouzeix-Raviart elements. The approximation of the momentum balance is obtained by usual finite element techniques. Since the pressure is piecewise constant, the discrete mass balance takes the form of a finite volume scheme, in which we introduce an upwinding of the d...

Study of the mixed finite volume method for Stokes and Navier-Stokes equations

We present finite volume schemes for Stokes and Navier-Stokes equations. These schemes are based on the mixed finite volume introduced in [6], and can be applied to any type of grid (without “orthogonality” assumptions as for classical finite volume methods) and in any space dimension. We present numerical results on some irregular grids, and we prove, for both Stokes and Navier-Stokes equation...

Finite Volume Solution of a Cylinder in Cross Flow with Heat Transfer

A finite-volume model has been developed to study incompressible forced flow heat transfer of air over a circular cylinder in cross flow. An artificial compressibility technique is applied to couple the continuity to the momentum equations. The proposed explicit finite-volume method (FVM) uses a novel discretization in time and space. The governing equations are solved by time-marching using a ...

A convergent finite element-finite volume scheme for the compressible Stokes problem. Part II: the isentropic case

In this paper, we propose a discretization for the (nonlinearized) compressible Stokes problem with an equation of state of the form p = ργ (where p stands for the pressure and ρ for the density). This scheme is based on Crouzeix-Raviart approximation spaces. The discretization of the momentum balance is obtained by the usual finite element technique. The discrete mass balance is obtained by a ...

Numerical Approximation of the General Compressible Stokes Problem

In this paper, we propose a discretization for the compressible Stokes problem with an equation of state of the form p = φ(ρ) (where p stands for the pressure, ρ for the density and φ is a superlinear nondecreasing function from R to R). This scheme is based on Crouzeix-Raviart approximation spaces. The discretization of the momentum balance is obtained by the usual finite element technique. Th...
