In this project, an innovative, interactive, general purpose solver for high-speed
compressible flows that uses unstructured, solution-adaptive meshes composed of tetrahedral
cells was investigated. Such a computer program will represent a significant advance
in the state of the art and will be a powerful tool for the study of inviscid and
turbulent three-dimensional transonic and supersonic flows.
The Phase I effort demonstrated that an unstructured, second-order accurate, finite-volume
formulation is able to produce accurate, highly detailed flow solutions. The unstructured
mesh formulation easily accommodates complex flow features such as shocks and boundary
layers. The mesh refinement algorithm provides highly localized mesh refinement while
maintaining excellent cell aspect and volume ratios.

Potential Commercial Application: This code will have significant applications for
research and design involving high speed flows in turbines, compressors, inlets,
aircraft, and hypersonic flight vehicles.
