Abstract
Compressor design is critical for enhancing the performance of various propulsion and power generation systems. This thesis introduces a novel automation strategy and coding tools designed to automate the generation of computational speedline performance maps for a wide range of compressors. This approach facilitates rapid design iteration across different compressor geometries and operating conditions without manual intervention. By integrating an external programming language with a computational fluid dynamics solver, the developed automation logic adjusts the compressor’s outlet stagnation pressure based on a developed control logic. This automated speedline generation code was then implemented within an automated compressor geometry optimization code to enhance compressor performance by automatically altering the hub dimensions. The results demonstrate that the automation tools and strategy are able to computationally generate a speedline performance map without user intervention. Moreover, the automated geometry optimization code successfully modified the hub geometry to identify more optimal hub designs.
