Stabilization of cell-centered compressible Lagrangian methods using subzonal entropy
نویسندگان
چکیده
This work deals with the stabilization of early stages of Lagrangian calculations of compressible gas dynamics in the context of cell-centered discretization. We describe a totally conservative algorithm based on an entropy analysis of the distortion of a Lagrangian mesh. The resulting scheme is an extension of the cell-centered GLACE scheme [10]. Numerical tests are proposed to assess the accuracy and robustness.

A Cell-Centered Lagrangian Scheme for Two-Dimensional Compressible Flow Problems
We present a new Lagrangian cell-centered scheme for two-dimensional compressible flows. The primary variables in this new scheme are cell-centered, i.e., density, momentum and total energy are defined by their mean values in the cells. The vertex velocities and the numerical fluxes through the cell interfaces are not computed independently contrary to standard approaches but are evaluated in a...
متن کاملA high-order cell-centered Lagrangian scheme for two-dimensional compressible fluid flows on unstructured meshes
We present a high-order cell-centered Lagrangian scheme for solving the two-dimensional gas dynamics equations on unstructured meshes. A node-based discretization of the numerical fluxes for the physical conservation laws allows to derive a scheme that is compatible with the geometric conservation law (GCL). Fluxes are computed using a nodal solver which can be viewed as a two-dimensional exten...
متن کاملAngular momentum preserving cell-centered Lagrangian and Eulerian schemes on arbitrary grids
This talk is dedicated to multi-dimensional numerical simulation of Euler equations for compressible flow problems. To fulfill the conditions of the Lax-Wendroff theorem, it is required that a numerical scheme conserves the mass, momentum and total energy. Associated with the consistency and the increase of the entropy, these conservation properties are sufficient, in 1D, to ensure that a conve...
متن کاملA high-order cell-centered Lagrangian scheme for compressible fluid flows in two-dimensional cylindrical geometry
The goal of this paper is to present high-order cell-centered schemes for solving the equations of Lagrangian gas dynamics written in cylindrical geometry. A node-based discretization of the numerical fluxes is obtained through the computation of the time rate of change of the cell volume. It allows to derive finite volume numerical schemes that are compatible with the geometric conservation la...
متن کاملMulti-scale Godunov-type method for cell-centered discrete Lagrangian hydrodynamics
This work presents a multidimensional cell-centered unstructured finite volume scheme for the solution of multimaterial compressible fluid flows written in the Lagrangian formalism. This formulation is considered in the Arbitrary-Lagrangian-Eulerian (ALE) framework with the constraint that the mesh and the fluid velocity coincide. The link between the vertex velocity and the fluid motion is obt...
