LImitation of CFX program in turbomachinery
daer all please, i want to know what are the limitation of CFX software offered in ANSYS,my work focused in axial flow turbine ,but in all documentation i coud not found the limitation of the pachage

Re: LImitation of CFX program in turbomachinery
it is a really question.i want to know the different between ANSYS CFX and NUMECA FINE/TURBO for turbomachinery,but it is really quiet convient to do the pre and post.and i dont know if it can run pre and post in parallel way?

Re: LImitation of CFX program in turbomachinery
CFX can simulate an axial flow turbines.
There are three different models which allow you to *not* simulate the entire 360 degree machine. Frozen Rotor and Stage can be used for steady state calculations with a change of pitch or shape. Frozen Rotor gives a ball park approximation at best, stage mixes out the flow going from one component to the next. Transient Rotor Stator is used for transient and accounts for change of pitch and shape between components. |

There is a software named TurboGrid about the turbomachinery.

Hi HekLeR,
In my case, I made a circular domain and the center is not located at the origin. But, the domain is rotating around the origin though it should rotate around the center of the domain. Can you please tell me the way to change the pivot of rotating domain when I am using the Transient Rotor stator Model? |
Re: LImitation of CFX program in turbomachinery
I think I answered this already. See my other post. Use teh two point option or setup a coordinate frame which is not centered at 0,0,0. Select your custom coordinate frame axis x,y or z (depending which one lines up with the machine axis).

HekleR,
Thanks a lot. Farid |
