Perspective on Unstructured Grid Flow Solvers

摘要

This survey paper assesses the status of compressible Euler and Navier-Stokessolvers on unstructured grids. Different spatial and temporal discretization options for steady and unsteady flows are discussed. The integration of these components into an overall framework to solve practical problems is addressed. Issues such as grid adaptation, higher order methods, hybrid discretizations and parallel computing are briefly discussed. Finally, some outstanding issues and future research directions are presented.
