GPPS 2nd Turbomachinery CFD Workshop
The GPPS 2nd Turbomachinery CFD workshop will take place as part of the GPPS Chania22 conference on September 11, 2022. The workshop will take place in a hybrid format (the conference will take place in person).
Built upon the experience from the 1st Turbomachinery CFD workshop, we would like to launch our 2nd Turbomachinery CFD Workshop. The theme of this workshop is Validation and Verification of RANS Turbomachinery Solvers on the TUDa-GLR-OpenStage Transonic Axial Compressor and the BUAA Low Speed Large Scale Axial Compressor-Stage B. More participants are expected for this workshop, as quite a few participants from industry(SIEMENS Energy, IHI, ITP, Aero Engine Academy of China, Korea Aerospace Research Institute) and software companies (Cadence Design Systems, Turbostream) have already confirmed their participation.
Motivation
RANS simulation is the industrial workhorse for predicting turbomachinery flows. However, due to the errors and uncertainties involved in the experiments and CFD models, users can occasionally find inconsistencies and deficiencies in RANS results, which degrades users’ trust in RANS turbomachinery solvers. This workshop aims to improve users’ trust in RANS turbomachinery solvers by conducting a validation and verification (V&V) study on two cases: the TUDA-GLR-OpenStage transonic axial compressor and the BUAA low speed large scale axial compressor-Stage B.
Information about the two cases
TUDA-GLR-OpenStage transonic axial compressor consists of a blisk rotor, a 3D optimized stator and an OGV.
Available measurement data:
• Compressor performance at 65% and 100% design speed (ME30-ME15)
• 1D total pressure and temperature profile @ME15
• 1D flow angle and total pressure profile @ME21
• 1D total pressure and temperature profile @ME30
• 2D planar measurement (total pressure and temperature) @ME30
More details about the case can be found from the following publications.

BUAA low speed large scale axial compressor-Stage B consists of an IGV, a rotor and a stator.
Available measurement data:
• Compressor performance (Plane0-Plane5)
• Inlet boundary layer (blockage) @Plane0
• Five-hole probe measurement @Plane 2/3/4
• Flow measurement inside blade passage
• Oil-flow results in stator passage

Objectives
- Troubleshooting and version control of numerical models in existing in-house and commercial turbomachinery RANS solvers.
2. Enhance understanding of RANS prediction capability for subsonic and transonic axial compressors
3. Develop a best practice guide of RANS solvers for subsonic and transonic axial compressors.
4. Promote education of the next generation turbomachinery CFD engineers.
How to participate
Please note: For those who submit their data after the deadline but before the workshop, their data may not be included in the workshop summary presentation, but will be included in a final report.
Submitting your Data
Please send your data using WeTransfer, or local alternative to the following representatives:
