Knowledge-Based Parametric Modeling for Nozzles

Abstract

This paper describes a new, and unique, system for design and analysis of a family of parts with a specific focus on gas turbine nozzles. The system, built on the tenets of knowledge-based engineering (KBE) within an object-oriented framework, supports the notion of scalable products that can be resized through reparametrization. The KBE system for the parametric design of nozzles has been integrated with a Topology and Geometry Utility System (TAGUS) and geometry-based mesh generators (QUADTREE and EXTREME) to develop a turnkey system. The resulting system is shown to help reduce the design cycle time and to increase engineering productivity by representing design and manufacturing information as part of the complete product definition.

Knowledge Based Engineering for Hydrogen Gas Turbines and Burners Design: a review

“…Reduction of the risk of a drop back to the conceptual phase [25] Capture and reuse the expert experience efficiently [27,31,33,37] Heighten the design efficiency and quality [27,37] Portable web-based development and runtime environments [28] Independence from proprietary CAD systems [28] Automatic caching and dependency tracking for scalable runtime performance of large models [28] Minimal source code volume [28] More efficient, clearer and easier model development and debugging [22,26,28,31,34,35,36] More information on the model (what, why, how) [30] E3S Web of Conferences 334, 05001 (2022) EFC21…”

“…Shorten learning curves for novice engineers [22,31] Shorten Design cycle time [22,34,35,36,37] Given the peculiar features of hydrogen combustion, existing gas turbines can be adapted for using hydrogen as a fuel integrating improved burners that are able to work at high temperature. Therefore, one of the major design challenge is related to re-configure existing gas turbines and to integrate new burners/combustor with them.…”
