Abstract:A 2 n tree-based Cartesian grid generation method has been developed recently for complex geometries to simulate viscous flows. The "viscous" Cartesian grid is capable of resolving boundary layers with high-aspect ratio projected viscous layer grids. Compared with an Octree data structure, the 2 n tree data structure supports anisotropic grid adaptations in any of the coordinate directions in an arbitrary manner. This capability enables flow features such as shocks, shear layers, and wakes to be resolved very … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
