Open Test Cases

Despite the technological advancements and rapid developments in computational resources and capabilities, the necessary confidence is still restrained to cope with the challenging demands of next generation aero engines or industrial gas turbines. Validation benchmark test cases are crucial for scientific research and industry collaborations. Therefore, the Institute of Gas Turbines and Aerospace Propulsion contributes with distinct and high quality open test case data.

The Transonic Compressor Darmstadt (TCD) at Technical University of Darmstadt (TUDa) contributes to various research areas with respect to modern transonic compressors for more than 25 years. The experiments at high speed operating conditions and technology readiness level TRL 4-5 play a key role for further physical understanding and advancements.

The introduced TUDa-GLR-OpenStage Transonic Compressor data set, including geometry information and measurement data, provides a comprehensive test case for the turbomachinery community. Hence, it enables high quality measurements to foster improvements in numerical modeling and validations, in order to tackle current and future challenges in turbomachinery applications.

The TUDa-GLR-OpenStage will be published with respect to a release schedule and is currently available via the Global Power and Propulsion Society data sets.
