A multislope MUSCL method on unstructured meshes applied to compressible Euler equations for swirling flows
A nite volume method for the numerical solution of axisymmetric inviscid swirling ows is presented. The governing equations of the ow are the axisymmetric compressible Euler equations including swirl (or tangential) velocity. A rst-order scheme is introduced. In this one, convective uxes at cell interfaces are evaluated by the Rusanov or the HLLC numerical ux and geometric source terms are disc...

متن کاملMultislope MUSCL method for general unstructured meshes
The multislope concept has been recently introduced in the literature to deal with MUSCL reconstructions on triangular and tetrahedral unstructured meshes in the finite volume cell-centered context. Dedicated scalar slopes are used to compute the interpolations on each face of a given element, in opposition to the monoslope methods in which a unique limited gradient is used. The multislope appr...
متن کاملMonoslope and multislope MUSCL methods for unstructured meshes
We present new MUSCL techniques associated with cell-centered Finite Volume method on triangular meshes. The first reconstruction consists in calculating a one vectorial slope per control volume by a minimization procedure with respect to a prescribed stability condition. The second technique we propose is based on the computation of three scalar slopes per triangle (one per edges) still respec...
متن کاملA Two-Dimensional Fourth-Order CESE Method for the Euler Equations on Triangular Unstructured Meshes
Previously, Chang reported a new high-order Conservation Element Solution Element (CESE) method for solving nonlinear, scalar, hyperbolic partial differential equations in one dimensional space. Bilyeu et al. have extended Chang’s scheme for solving a onedimensional, coupled equations with an arbitrary order of accuracy. In the present paper, the one-dimensional, high-order CESE method is exten...
