Automated, Parametric Geometry Modeling and Grid Generation for Turbomachinery Applications

The objective of this proposal is to develop a highly automated software system for rapid geometry modeling and grid generation for turbomachinery applications. The proposed system features a graphical user interface for interactive control, a direct interface to commercial CAD systems, support for IGES geometry output, and a scripting capability for parametric definition of geometries and for obtaining a high level of automation. In addition, the scripting facility enables elaborate end-user customization of the tool.The design of the proposed system and the beta testing of the software will be done in collaboration with the Center of Gas Turbines and Power at Penn State University (Dr. Lakshminarayana) and Dresser Rand (Dr. Lee Hill).In Phase I, a prototype of the system will be developed and demonstrated on an important subclass of turbomachinery geometries, such as impellers. This Phase will demonstrate the feasibility of the approach. In Phase II, the full system will be developed and tested on a wide variety of turbomachinery geometries. Additional industry participation is also planned. ~990048 ~
