Unstructured Density Based CFD Methodology for Gas Turbine Combustor Applications

	Glenn Research Center 1993 Phase II Unstructured Density Based CFD Methodology for Gas Turbine Combustor Applications CFD Research Corporation Huntsville, AL
INNOVATION A new methodology for efficient generation of large high-quality tetrahedral and prismatic meshes for CFD gas turbine combustor and other applications	CFD-GEOM, with a direct link to UniGraphics, accepts true CAD data without IGES translation and generates complete unstructured grid systems with minimal user input Optional Powerpoint file
ACCOMPLISHMENTS Developed software package CFD- GEOM with: Automatic curvature based unstructured grid generation on trimmed-NURBS geometry models Interactive assignment of boundary and volume conditions, directly on the geometry, configurable for various flow solvers Tetrahedral grid mesher for large grids (100K-300K cells per minute) based on Delauney and Advancing Front technique Prismatic grid mesher for resolution of boundary layers based on Advancing Layers Method Direct interface to commercial CAD systems
COMMERCIALIZATION CFD-GEOM is being marketed as a stand-alone product for structured and unstructured grids, as well as in conjunction with CFDRC flow solvers Installed at more than 250 organizations worldwide for a variety of CFD grid applications. The average license fee is ~$5K	GOVERNMENT/SCIENCE APPLICATIONS Standard grid generation software for the National Combustor Code (NCC) computational framework Several Phase III extensions by NASA and CFDRC with NASA contributing $375K
