Abstract:

As part of a project with an aircraft turbine manufacturer, the proposed paper focuses on an innovative solution for building and democratizing the use of automated engineering workflows at scale based on the history of compressor performance maps evaluation. The compressor map allows to easily review and analyze its efficiency, pressure ratio and surge limit across the operating range. Its construction is based on a set of standard CFD simulations. However, combining these simulations to reconstruct the map requires custom logic, including automatic refinement and additional evaluations to explore specific areas of the map. The complex logic behind it remains a fixed and repetitive process. Only domain experts can support and are allowed to alter it. Democratization becomes a must as there is a large proportion of non-experts who need to use the described methodology frequently. To achieve this, the engineering process behind it must be assembled in a simple form to remain accessible. In addition, multiple competitive runs from different users and massive heavy CFD evaluations require a powerful resource management process. The presentation shows how compressor performance map construction can be scaled with a single author and multiple users, and efficiently managed through user interfaces and applications. The same process can be applied to typical late-stage and even inter-project design changes. Efficiency gains through reduced effort in repetitive tasks and centralized management of the methodology are emphasized.
