N2 - A finite volume method for solving chemically reacting flows on unstructured meshes has been developed and successfully tested against experimental results and various computational simulations. Whereas this stand alone code, FVFLO-NCSU, is capable of resolving flows for high-speed propulsion devices with complex geometries, unstructured mesh algorithms are inherently inefficient when compared to their structured mesh counterparts. However, the advantages of structured algorithms in developing a flow solution in a timely manner can be negated by the amount of time required to develop a mesh for complex geometries. To help alleviate some of the difficulties in creating these complex meshes, the global domain can be split up into numerous smaller blocks where adjacent block inter- faces may or may not have matching nodes. One code capable of solving chemically reacting flows on these multiblock grids is VULCAN, which uses a nonconservative approach for patching nonmatching (or non-C0) block interfaces. Initial work towards development of a regionally structured/unstructured finite volume method has been completed through integration of parts of the FVFLO-NCSU code into VULCAN. Parallel to this work has been the development of an algorithm capable of replacing non-C0 block interfaces with an unstructured mesh to ensure conservation across these boundaries.
