[TurboGrid] GE rotor B geometry for Ansys turbogrid

sonny · July 7, 2009, 18:18

Guys

I'm trying to simulate flow in a compressor cascade(GE rotor B) using Ansys CFX. But I needed to get the meshing done with Ansys turbogrid 11. I got the GE rotor B blade profile data from a desertaion by Muthanna(1998) but turbogrid requires three data files: profile, hub and shroud. I created these other files on my own from the blade profile data and got a model data doesn't look right for turbogrid meshing.

I need some help with getting a complete data file or an advice on how to create the right data files for my hub and shroud

Hub and shroud curves can be obtained by projecting the profile to meridional plane.

the guy probably found him a job already !!! that was back in 2009

I did not see the date.. Yes, what you said was right.. :-)

Hi,

Please, I stuck with creating the blade and hub data files for turbogrid. I opened the files in the turbogrid tutorial on ICEM and saw that the data for the hub is a polynomial created some how to pass through the LE. and TE. of lowest airfoil of the blade. I am wondering if I can extract these data from solidworks or I should use bladegen to create them. I already have the data for the airfoil, but I do not know how to manipulate the hub coordinate to agree with the blade's and be valid for TurboGrid.

Thanks

Aziz

Dear colleague, what version of ansys are you using?

I can help you but right now I have version 12

Maybe if you send me a saved version that I can open, I can help you

Best regards

Thanks for your reply gerardosrez,

The ansys I have in school is version 13 and 14. The airfoil is in fact a water turbine hydrofoil. The blade is untested and has a constant cross-section. I have drawn the all rotor on a solidworks, but I read in a thread that I should create the .curve files of the blade airfoil and hub curve in BladGen in order to import to TurboGrid . I have already imported the hydrofoil to BladeGen but I stuck with the hub.

Thanks again for your help.
