SPE 163649: The Multiscale Finite Volume Method on Unstructured Grids
Finding a pressure solution for large-scale reservoirs that takes into account fine-scale heterogeneities can be very computationally intensive. One way of reducing the workload is to employ multiscale methods that capture local geological variations using a set of reusable basis functions. One of these methods, the multiscale finite-volume (MsFV) method is well studied for 2D Cartesian grids, ...
متن کاملA high-order spectral difference method for unstructured dynamic grids
A high-order spectral difference (SD) method has been further extended to solve the three dimensional compressible Navier–Stokes (N–S) equations on deformable dynamic meshes. In the SD method, the solution is approximated with piece-wise continuous polynomials. The elements are coupled with common Riemann fluxes at element interfaces. The extension to deformable elements necessitates a time-dep...
متن کاملEfficient Implementation of High-Order Spectral Volume Method for Multidimensional Conservation Laws on Unstructured Grids
An efficient implementation of the high-order spectral volume (SV) method is presented for multidimensional conservation laws on unstructured grids. In the SV method, each simplex grid cell is called a spectral volume (SV), and the SV is further subdivided into polygonal (2D), or polyhedral (3D) control volumes (CVs) to support high-order data reconstructions. In the traditional implementation,...
متن کاملHigh-Order Spectral Volume Method for the Navier-Stokes Equations on Unstructured Grids
In this paper, the spectral volume (SV) method is extended to solve the Navier-Stokes equations by treating the viscous terms with a mixed formulation named local Discontinuous Galerkin approach. The SV method combines two key ideas, which are the basis of the finite volume and the finite element methods, i.e., the physics of wave propagation accounted for by the use of a Riemann solver and hig...
متن کاملA High Order Accurate Unstructured Spectral Finite Volume Implicit Algorithm for Inviscid Compressible Flows
Abstract. The purpose of this work is to develop a methodology that achieves high order spatial discretization for compressible aerodynamic flows based on the spectral finite volume method for hyperbolic conservation laws. High order methods are necessary on the analysis of complex flows to reduce the number of mesh elements one would otherwise need if using traditional second-order schemes. In...
