Comparison of node-centered and cell-centered unstructured finite-volume discretizations. Part I: viscous fluxes
Discretization of the viscous terms in current finite-volume unstructured-grid schemes are compared using node-centered and cell-centered approaches in two dimensions. Accuracy and efficiency are studied for six nominally second-order accurate schemes: a node-centered scheme, cell-centered node-averaging schemes with and without clipping, and cell-centered schemes with unweighted, weighted, and...
متن کاملComparison of node-centered and cell-centered unstructured finite-volume discretizations: inviscid fluxes
Cell-centered and node-centered approaches have been compared for unstructured finite-volume discretization of inviscid fluxes. The grids range from regular grids to irregular grids, including mixed-element grids and grids with random perturbations of nodes. Accuracy, complexity, and convergence rates of defect-correction iterations are studied for eight nominally second-order accurate schemes:...
متن کاملComparison of Node-Centered and Cell-Centered Unstructured Finite-Volume Discretizations: Viscous Fluxes
Finite-volume discretization schemes for viscous fluxes on general grids are compared using node-centered and cell-centered approaches. The grids range from regular grids to highly irregular grids, including random perturbations of the grid nodes. Accuracy and complexity are studied for four nominally second-order accurate schemes: a node-centered scheme and three cell-centered schemes (a node-...
متن کامل“Way-Centered” versus “Truth-Centered” Epistemologies
In recent years, a criticism of “indigenous knowledge” has been that this idea makes sense only in terms of acquaintance (or familiarity) type and practical (or skills-type) knowledge (knowledge-how). Understood in terms of theoretical knowledge (or knowledge-that), however, it faces the arguably insurmountable problems of relativism and superstition. The educational implications of this would ...
متن کاملA cell-centered diffusion scheme on two-dimensional unstructured meshes
We propose a new cell-centered diffusion scheme on unstructured meshes. The main feature of this scheme lies in the introduction of two normal fluxes and two temperatures on each edge. A local variational formulation written for each corner cell provides the discretization of the normal fluxes. This discretization yields a linear relation between the normal fluxes and the temperatures defined o...
