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 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

  1. 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

1.    People who attended the virtual GPPS Xi’an21 technical conference can request access (see point 3 below) to the geometry, experimental data (for TUDA-GLR-OpenStage only), boundary conditions, and official grids of two test cases without registration for Chania22
 
2.    People who have not attended the GPPS Xi’an21, need to register for the Chania22 first. The CFD Workshop is complimentary for Chania22 registrants (both day-pass and full conference tickets), but it is also possible to register for the CFD workshop only, for a fee. The registration to GPPS Chania22 will open shortly!
 
3. Download and complete the Legal Agreement for each required data set, then using our online Data Request form send your completed PDF. Upon successful application, you will receive a download link of the geometry, experimental data (for TUDA-GLR-OpenStage only), boundary conditions, and official grids of two test cases.
 
4.    Please submit your results by 1st August, 2022. The data format of submissions will be provided in future updates.
 
5.    All workshop attendees have to register for the CFD workshop or the GPPS Chania22 conference to attend and/or present their results and/or have their submitted data processed by the organizers.
