How to transform the Cylindrical turbo surface into flat surface in cfd-post?

sunset · March 16, 2013, 01:06

Hellow,i am interseted in the velocity of the centrifugal compressor impeller outlet. But,i can't get the flat surface at the outlet of the impeller.I just know to get a turbo surface at the impeller outlet. So,does anyone how to do it in cfd-post?
Thank you !!!

This sounds like basci post processing and is well covered by the tutorials. Have you done the tutorials?

Does anyone know how to do it?
I am hungry to know that.
Please!!!!!

You can specify a plane over your outlet and draw the velocity over this plane.

Yes,i know that . I insert a turbosurface and specify the variable. But ,the plane is cylindrical. What i want is a flat plane. So,my problem is to transform the cylindrical into a flat plan. Do you really understand what i want to do?
Please!!!!!!!

No, I do not understand what you want to do.

Do you want to put a flat plane through your domain, or do you want to take the existing cylindrical section and map it to a flat surface? Or something else?

I want to take the existing cylindrical section and map it to a flat surface.
I will show you some pictures which is the experimental result.
I want to compare my numerical result to it .

I cannot think of a way of doing this all in CFD-Post. I would export the data from your cylindrical surface and plot it using an external package, like matlab, excel (if you must), python, tecplot or whatever you wish.

Thank you for your advice.
I am going to use tecplot.
