Hi, everyone,
Open test cases of centrifugal compressors are very useful to validate CFD code. Thanks are due to the folks who release coordinates of geometry and measurement results. Every open test case is fairly precious. However, some test cases may not be known by people who want them. So I start this thread and would like to collect open test cases here.

Could you provide names and related papers releasing coordinates and test data of open test cases of centrifugal compressors if you know any. Particularly, if the data concerning surge and stall also has been released in a test case, please write a note about it.

Here are some cases I know:
1. SRV2-O, coordinates and test data(http://proceedings.asmedigitalcollec...icleid=1571244)

2. Radiver and Radiver 2, homepage of the case(http://www.ist.rwth-aachen.de/typo3/...php?id=374&L=1), they will send you data if you ask.

3. NASA CC3 centrifugal compressor, coordinates and test data(http://ntrs.nasa.gov/search.jsp?R=19970024917), measurements of surge(http://ntrs.nasa.gov/search.jsp?R=20030013622)

4. NASA Low-Speed Centrifugal Compressor ,coordinates and test data(http://ntrs.nasa.gov/search.jsp?R=19950025564)

Thanks.

how do i generate the compressor for my cfd using the impeller bladecoordinates is it ANSYS or any other cfd solver?

Hi, you might not be able to import those coordinates directly into a mesh generator. I usually use EXCEL to rearrange the coordinates to produce a new coordinates file in which the format is compatible to a mesh generator.

do i import the impeller blade coordinates in to the mesh generator? or the flow path as well . I am unable to build a flow path with the given cordinates?
